A winding machine (1) for a traversing application of a winding material (51) to a spool sleeve (27) comprises a spindle (8) which is supported for being rotated and for having a fixed axial position. The spindle (8) comprises an inner recess. The winding machine (1) comprises a drive driving the spindle (8) for a rotational movement and a traversing carriage (20). The traversing carriage (20) is supported on the spindle (8) for being movable with a traversing motion (18) in an axial direction relative to the spindle (8). A first coupling element serves for transmitting the rotational movement of the spindle (8) to the traversing carriage (20) and a second coupling element serves for transmitting the traversing motion (18) of the traversing carriage (20) to the spool sleeve (27). The winding machine (1) also comprises an actuation mechanism (30) executing the traversing motion (18). The actuation mechanism (30) is coupled to the traversing carriage (20) for transmitting the traversing motion (18) from the actuation mechanism (30) to the traversing carriage (20). The actuation mechanism (30) extends through the inner recess of the spindle (8).

Method and apparatus for producing coreless rolls of paper

A machine forms a roll of convolutely wound web material. The machine includes a winding apparatus configured to receive a mandrel and the web material and wind the web material around the mandrel. A pulling device pulls the mandrel longitudinally to remove the mandrel from the roll after forming the roll. The machine further includes a restraint that engages the peripheral surface of the roll when the mandrel is pulled longitudinally to remove the mandrel from the roll. A method is also provided. In one aspect of the method, a web material is wound around a mandrel to form a roll of convolutely wound web material. The mandrel is pulled longitudinally after the step of winding the web material around the mandrel. The periphery of the roll is restrained from moving axially when the mandrel is pulled longitudinal. The mandrel is then removed from the roll.

Surface rewinder with center assist and belt and winding drum forming a winding nest

A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

A clasp is configured to engage an end of a tube. The clasp has a shaft that is insertable into a tube. The clasp includes a housing with clamping blocks that are spaced circumferentially around the shaft. The clamping blocks are moveable between a disengaged position in which the clamping blocks are spaced radially outwardly from the shaft at a distance sufficient such that a tube is insertable between the shaft and the clamping blocks, and an engaged position in which the clamping blocks are positioned radially inward of the disengaged position toward the shaft and are configured to press a tube disposed between the blocks and the shaft against the shaft. The clasp has at least one actuator engageable with at least one clamping block of the plurality of clamping blocks to move the at least one clamping block between the disengaged position and the engaged position.
