DESCRIPTION OF THE INVENTION

(31) In general terms, the present invention refers to a peripheral clamping mini-blade for a superficial roughing down which body (2) has an inner edge (4) in which there is at least one transversal tab (6) that constitutes a retention means of the mini-blade (1) in an adapter device (20); between the inner (4) and external (3) edges, the body (2) has the sufficient extension to form the clamping portions (7) (8) that allow the application of peripheral clamping tabs (30). The invention also refers to a mounting adapter device that, for the mounting in a rotary work structure (40) of pneumatics roughing down, includes clamping sets (20) composed of ending supports (21) (22) and intermediary separator supports (23), all of which have clamping transversal peripheral tabs (30) that include jaws able to clamp the clamping portions (7)(8) of the mini-blades (1).

DETAILED DESCRIPTION OF THE INVENTION

(32) More particularly, present mini-blade (1) includes a laminar body (2) or toothed blade, through which the superficial roughing down of the wheel thread of the pneumatics that will thereafter be retreated.

(33) Even more particularly, the mini-blade (1) includes a laminar body (2) or blades of low height and curved edges. One of those convex curved edges is a toothed edge (3), for instance, having double teeth capable of working to opposite sides and which conformation allows them to auto-sharpen, at the same time they work.

(34) The toothed edge (3) extends until the endings (9) in which the laminar body (2) of the mini-blade (1) terminates.

(35) Opposite to above-mentioned toothed edge (3), the laminar body (2) ends in a concave inner edge (4). In said inner edge (4) there is a fold (5) or bend, through which the transversal tab (6) is projected.

(36) This transversal tab (6) constitutes a retention means for an adaptater device (20) that allows the mounting in a rotary work structure (40).

(37) Above-mentioned tab (6) is transversal with respect to the laminar body (2) from which it is projected. To fulfill its function property, preferably, this tab (6) may be perpendicular regarding the laminar body (2) or also form an angle not bigger than 90.

(38) Even if it is foreseen that the extension or height of the laminar body (2), between the external (3) and inner (4) edges, be as short as possible. It will be enough if it has the sufficient extension such as to be able to apply the corresponding peripheral clamping transversal tabs (30) to a clamping set (20) of an adapter device.

(39) In such a way, the mini-blade (1) includes a clamping part, that includes the transversal tab (6) and some clamping portions (7)(8) adjacent to the body (2). The rest of the body (2) and the external toothed edge (3), constitute a part of the work that is applied to the work of superficial roughing down.

(40) The possibility of incorporating openings of compensation (61) in the transversal tab (6) that, for instance, allow compensation of eventual distortions of the laminar body (2) has been foreseen.

(41) Adapter Device

(42) On the one hand, present adapter device is useful for the mounting of mini-blades (1) or toothed blades, that are grouped in several units to produce the superficial roughing down of pneumatics, in particular to rough down the wheel tread and that said pneumatic remains in conditions to be retreaded.

(43) On the other hand, present adaptater device is prepared to be mounted on rotary work structures (40) that usually have one set of mounting bodies (41)(42). This set includes a first and second bodies (41)(42) of mounting, among which the mini-blades (1) are mounted clamped by the clamping sets (20) of the adapter device. For the assemble of the rotary work structure (40), a plurality of bolts (43) that firmly bind the set (20)(40), are set.

(44) Present device includes clamping sets (20) capable of clamping mini-blades (1) of the small size in a peripheral part of said sets (20). Each clamping set (20) includes a set of ending supports (21)(22) and, according to the operational necessities, it can use one or more intermediary separator support (23).

(45) In general terms, all supports (21)(22)(23) will have a peripheral curved profile so that they can support the mini-blades (1) protruding with regards to the rotary work structure (40) and to equivalent radial distances.

(46) More specifically, in each of the clamping sets (20), the sets of ending support (21)(22) include a first ending support (21) and a second ending support (22).

(47) The first ending support (21) includes one or more transversal peripheral tabs (30), regarding the body from which they are projected, that work as one of the components of the jaws for the mini-blades (1). In an adjacent manner to the transversal peripheral tab (30), to the inside of the first ending support (21), there are guide members (31) that, in different embodiments, may consist, for example, in a plurality of ears, a plurality of tabs, a continuous tab, etc. These guide members (31), together with the transversal peripheral tab (30) form a peripheral socket that works as positional guide (32) in which the tabs (6) of the mini-blades (1) are fitted.

(48) The second ending support (22) includes one or more transversal peripheral tabs (30) regarding the body from which they are projected, which work as another of the components of the jaws for the mini-blades (1).

(49) In order to contribute to a better clamping effectiveness of the jaw, the possibility that the transversal peripheral tabs (30) may end in plane edges has been foreseen, in such a way that they make use of all the thickness of the body that comprises them.

(50) The intermediary separator supports (23) include clamping transversal peripheral tabs (30) that are projected to opposite sides, in such a way that they are applied both to the front part [inner clamping portion (7)] and to the back part [external clamping portion (8)] of the mini-blades (1).

(51) To such effect, it has been foreseen that the intermediary separator support (23) may consist of two or more parts united among themselves, for example: two component bodies (24)(25), a body with detachable, two bodies with detachable, solid parts, set of pressed sheets, shaped profiles, etc. In one of these embodiments, each of the component bodies (24)(25) of the intermediary separator support (23), has similar means than those of each ending support (21)(22), respectively.

(52) In order to ensure the clamping of the mini-blades (1), the inclusion of some containment ending tops (35), that include the endings (9) of the mini-blade (1), has been foreseen.

(53) The possibility of incorporating reliever means (10) in the transversal peripheral tabs (30) of the supports (21)(22)(23) that form the clamping jaws, has also been foreseen. These reliever means (10) may include a plurality of small openings that facilitate the aeration and prevent the accumulation of residues coming from the roughing down.

(54) On the other side, all the supports (21)(22)(23) that form the clamping set (20) are equipped with positioning members (33) that determine the mounting position and the relative separation among said supports (21)(22)(23), within the mentioned clamping set (20). In the present embodiment, some of the supports have sets of positioning means (33), among which a mounting guide (34) is formed in which a positioning member (33) of the support is arranged in a confronted manner.

(55) Finally, it has been foreseen that the different supports (21)(22)(23) may have openings for the different purposes. Some of these openings (37) are destined to allow the passage of the mounting bolts (43) that join the components (21)(22)(23) of the clamping set among themselves and with the rotary work structure (40). Other openings allow the reduction of weight and costs of the components, as well as avoid overheating.

(56) The possibility that the transversal peripheral tabs (30), capable of being confronted, have different heights has also been foreseen. For example, the transversal peripheral tab (30) that clamps the external clamping portion (8) of the mini-blade (1) is a Little bit more higher than the transversal peripheral tab (30) that clamps the inner clamping portion (7). In this way, said external clamping portion (8) can be clamped above the fold or bend (5).

(57) Operation

(58) The different supports (21)(22)(23) that form the clamping sets (20) are arranged attached one to another, in train, with the mini-blades (1) interspersed in their jaws, in such a way that the toothed external edge (3) of these last ones protrudes from the clamping set (20).

(59) In the assemble, the transversal peripheral tabs (30) of the confronted supports (21)(22)(23), compose the jaws in the middle of which the mini-blades are hold (1).

(60) In the cases of the first ending support (21) and the first body (24) component of the intermediary separator support (23), the transversal tab (6) of the mini-blade (1) enters into the positional guide (32), which is defined by the peripheral socket formed by the transversal peripheral tab (30) and the guide members (31). Therefore, the edge of the transversal peripheral tab (30) clamps to the inner clamping portion (7) of the mini-blade (1).

(61) Meanwhile, in those cases of the second ending support (22) and of the second body (23) component of the intermediary separator support (23), the edge of its transversal peripheral tab (30) clamps to the external clamping portion (8) of the mini-blade (1), in such a way that it forms a clamping jaw together with the transversal peripheral tab (30) of the adjacent support.

(62) The transversal peripheral tabs (30) are complemented by the presence of the ending tops (35), which prevent the displacement of the mini-blades (1) in the same direction as the clamping jaws. In this manner an immovable positional fixing of the mini-blades (1) and a firm clamping of them in said transversal peripheral tabs (30) are obtained.

(63) On the other side, several clamping sets (20) may be mounted over a same rotary work structure (40), to which mounting bodies (41)(42) they are related through bolts (43) that pass through both the mounting bodies (41)(42) and the supports (21)(22)(23). However, in no case shall they pass through the body (2) of the mini-blades (1) since their mounting is completely peripheral.

(64) Even if one set of ending supports (21)(22) is enough to clamp a mini-blade (1), several intermediary separators (23) are usually used to assemble clamping sets (20) with several files of mini-blades (1) that give a suitable roughing down width, in relation to the width of the wheel tread to which the device is applied to.

(65) On the other part, the use of the clamping sets (20) of different widths has been foreseen, in such a manner that one or more aligned mini-blades (1) may be included. Furthermore, this different width determines the amount of clamping sets (20) necessary to cover all the periphery of the rotary work structure (40).

(66) Undoubtedly, upon putting the present invention into practice, modifications may be introduced regarding certain construction details and form, without leaving the essential principles that are clearly explained in the claims below:
