DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0043] The edge tape cassette shown in FIGS. 1 and 2 has a cassette housing 18 in which the receiving element 1 according to the invention is accommodated. A winding core 3, which rotates with the receiving element 1, is preferably detachably attached to the receiving element. An edge tape 2 is wound-up on the winding core 3. The free end 2a of the edge tape 2 can be removed from the cassette housing 18 at an exit point. The winding core 3 is in particular connected to the receiving element 1 in a rotationally fixed manner. The rotation of the receiving element 1 thus causes a rotation of the winding core 3 and thus, depending on the direction of rotation, a winding or unwinding of the edge tape 2. In the edge tape cassette according to the invention, there are several options for how the edge tape can be wound or unwound. For this purpose, optional drives 19, 20, 22 can be provided at various points. The edge tape cassette is usually inserted into a slot in a cassette supply. A first option for the drive would then be, for example, the drive wheel 19, which can be driven, for example, via a switchable drive belt in the cassette shaft (not shown). A further possibility would be, for example, a drive roller 20 on an external tool (for example, a robot), said drive roller being delivered to the receiving element 1 at a specific position 21 on the upper side (or another narrow side) of the cassette. The frictional connection between the drive roller 20 and the receiving element 1 can cause the receiving element 1 to rotate and thus the edge tape roller 2 to rotate. A further option consists, for example, of detecting and conveying the edge tape end 2a directly at the outlet opening of the edge tape cassette by means of a pulley 22. All of these drives can be provided optionally, but can also be present in any combination.

[0044] Furthermore, a device 24 can be provided which is capable of either braking the edge tape roll 2 or the receiving element 1 or even fixing it completely, so that rotation is no longer possible. The latter can be used for transport purposes, for example.

[0045] Finally, the edge tape cassette can have a clamping device 23 in the region of the outlet opening, which is designed to clamp the pulled-out edge tape end 2a in the region of the outlet opening such that it does not accidentally slip into the edge housing 18. It can also be provided that the clamping effect of the clamping device 23 can be canceled such that the edge tape can be guided out of the cassette housing 18 without any problems and without hindrance. At the same time, this clamping device can also be designed as an edge guide, and in particular toward the narrow sides, guide elements can be present which prevent the edge tape 2a from slipping sideways.

[0046] The receiving element 1 according to the invention, which is now to be explained on the basis of a preferred embodiment with reference to FIGS. 3 to 6, has a winding core for fixing the wound-up edge tape 2. This winding core can preferably have an internal clamping device 3, as will be described below. However, the invention works with any type of winding core, an inner clamping device 3 described below is therefore only to be understood as an option.

[0047] The inner clamping device 3 is designed to exert outward forces on the inward surface 17 of the container of the wound-up edge tape 2.

[0048] The exemplary receiving element 1 advantageously has a disk-shaped base body 4. The base body 4 is advantageously at least essentially rotationally symmetrical.

[0049] The inner clamping device 3 advantageously has a pluralityin the example shown, threeclamping elements 5. These can be clamped to fix the wound-up edge tape 2 against the inwardly directed surface 17 of the container of the wound-up edge tape 2. The clamping elements 5 thus advantageously act in the manner of clamping jaws.

[0050] The clamping elements 5 are each slidably guided along the clamping direction X on the base body 4 for fixing the edge tape 2. In the example shown, the clamping direction X advantageously points in the radial direction in relation to the disk-shaped extension of the base body 4. The base body 4 has guiding elements 6 in order to allow the guiding of the clamping elements 5 along their respective clamping direction X. The guide elements 6 can be seen in FIG. 4. They engage in complementary grooves 7 into the clamping elements 5, which can be seen in FIGS. 2 and 3, and thus guide the movement of the tensioning elements 5.

[0051] Furthermore, the receiving element 1 according to the invention advantageously has a rotary element 8. The rotary element 8 is advantageously arranged centrally on the base body 4. The rotary element 8 is rotatable for fixing the edge tape 2. In the example shown, the rotatability is advantageously brought about by a rotatable mounting of the rotary element 8 on the base body 4. For this purpose, the rotary element has a central circular recess 9, into which a guide element 10 engages, which is received on the base body 4 and advantageously also has a circular design.

[0052] When the rotary element 8 rotates, contact surfaces 11 of the rotary element 8 slide, preferably in a spiral shape, on corresponding contact surfaces 12 of the clamping elements 5. The clamping elements 5 are thereby pressed outwards and against the inward surface 17 of the container of the edge tape 2. The mode of operation is evident from the comparison of FIGS. 2 and 3. Starting from FIG. 2, rotation of the rotary element 8 causes the contact surfaces 11 and 12 to slide against one another, such that the clamping jaws 5 are pressed outward in the radial direction until they reach a position shown in FIG. 3 by way of example, in which the edge tape 2 is fixed.

[0053] In order to ensure a better connection of the inner clamping device 3, the rotary element 8 and the clamping elements 5 have interlocking grooves 13 in the region of their contact surfaces 11 and 12. The interlocking grooves 13 are preferably also designed as spirals.

[0054] Likewise advantageously, the disk-shaped base body 4 has a first connecting element 14 for connecting a tool for fixing the edge tape 2 to the receiving element 1. This first connecting element 14 is advantageously designed such that it can additionally serve as a bearing element for the rotatable mounting of the receiving element 1. Furthermore, the inner clamping device 3 advantageously has a second connecting element 15, which in the example shown is arranged on the rotary element 8, for connecting the tool to the receiving element 1. The tool can thus be attached to the first connecting element 14 andusing the first connecting element 14 as a fulcrumcause the rotary movement of the rotary element 8 via the second connecting element 15.

[0055] Finally, the exemplary receiving element 1 according to the invention preferably has a fixing element 16. This can be, for example, a screw which presses the rotary element 8 against the base body 4 and thus generates a frictional connection to prevent the rotary movement of the rotary element 8 relative to the base body 4. In this way, a secure fixation of the inner clamping device 3 can be ensured. In the example shown, the interlocking grooves 13 advantageously provide for a positive locking of the clamping elements 5 on the base body 4 when the rotary element 8 is fixed on the base body 4 by the fixing element 16.
