The winding apparatus may include a plurality of guide roller assemblies that guide the fiber material unwound from the fiber unwinder to the rotor core. The winding apparatus may include a tension roller assembly that is provided between the plurality of guide roller assemblies and measures a tension of the fiber material. The winding apparatus may include a core support that is provided so that the rotor core is rotatable with respect to a core shaft, the rotor core is movable in an axial direction of the core shaft, and the rotor core is tilted with respect to the core shaft.

A cleaning station for removing surface impurities from the surface of a cylindrical magnetic rotor having an axis; the cleaning station comprises: a seat for housing the magnetic rotor in a rotatable manner about its axis; a first pin having an axis parallel to the axis of the magnetic rotor when housed in the seat, wherein the first pin is rotatable about its axis and supports a roll of adhesive tape; a second pin having an axis parallel to the axis for the first pin; wherein the second pin receives an initial unwinding end of the roll of adhesive tape supported on the first pin and is rotatable about its axis to progressively wind the adhesive tape about its axis during unwinding from the first pin; a motorization for commanding the unwinding of the adhesive tape from the first pin and the winding of the adhesive tape on the second pin; a pusher device configured to press the adhesive tape as it passes from the first and to the second pin against the magnetic rotor housed in the seat so that by dragging, the motion of the adhesive tape commands the rotation of the magnetic rotor about its axis and the surface impurities on the magnetic rotor migrate from the magnetic rotor to the adhesive tape remaining attached on the adhesive of the adhesive tape.

A supply roll for a wrap system of a baler implement includes a core having a circumferential wall surface forming a cylindrical shape concentric with a central longitudinal axis. A wrap material includes a length wound about the circumferential wall surface of the core, and defines an exterior circumference. The core and the wrap material cooperate to define a combined center of gravity. An axial position identifier is disposed on the exterior circumference of the wrap material, and is positioned relative to the combined center of gravity to define a desired lift location.

Rolling assembly for packaging web material in a roll having a base member with concave arcuate feed surface defining an upwardly-extending ramp, first intermediate member movably coupled to base member, and top member moveably coupled to at least one of base member or first intermediate member, top member having a concave arcuate pressure surface facing feed surface of base member. The base member, first intermediate member and top member collectively forming an iris with a feed space, the iris moveable between a first condition and a second condition, and configured to receive web material along the feed surface and direct the web material upwardly toward the top member to form a roll within the feed space, the iris moving toward a second condition as the roll of web material increases in cross dimension against the pressure surface of the top member.

A device is for automatically introducing a reinforcing sheet into a coreless coil applicable to a coreless winding machine. The winding machine includes such a device. In particular, a device is for introducing a reinforcing paper sheet into a coreless roll being wound with a continuous strip material by a coreless winding machine. The device includes a feeding tray for paper sheets, a feeder of the paper sheets taken from the feeding tray, and an introduction member of a paper sheet loaded into a roll being wound in the winding machine.

The present invention relates to a rewinding machine equipped with a support system for the reel and the ribbon-like product.

In particular, the invention relates to a rewinding machine (1) for a ribbon-like product (N), comprising: a fixed support structure which supports an unwinding unit (SV) and a rewinding unit (RB); an independent first carrier roller (2), movable along a direction parallel to a support surface of the rewinding machine (1); a second independent carrier roller (4), movable in the opposite direction with respect to the first carrier roller (2); a third roller (3), placed between the first (2) and second (4) carrier rollers and movable integrally with the first carrier roller (2); a set of driving rollers (110) placed along a path between the unwinding unit (SV) and the rewinding unit (RB); a web (10), forming at least one loop, made of a material with an air-permeable texture, said web (10) unwinding between the second carrier roller (4), the third roller (3), and the set of driving rollers (110); one or more suction boxes (6) placed under the web (10) to retain the ribbon-like product (N).

A rotating portion, mandrel, or spool for use with an automatic tarping equipment attachment is provided. The rotating portion, mandrel, or spool can including a central portion, a first end portion, and a second end portion. The central portion can be constructed to enhance cylindrical dimensional conformity to aid in prevention of bunching or uneven weight distribution during rolling or unrolling of a tarpaulin therefrom, and the first end portion and the second end portion can be used to reinforce end portions of the central portion.

The present application relates to a winding needle assembly, a winding apparatus, a production device, and a method for winding electrode assemblies in the field of battery production. The winding needle assembly includes a support seat and a winding needle rotatably connected to the support seat along the needle's axial direction. The winding needle extends outward from the support seat to form multiple winding portions outside the support seat, each configured to wind electrode assemblies. The assembly enables simultaneous winding of multiple electrode assemblies to increase production efficiency. While winding, the support seat reduces the length of the unsupported portion of the needle, enhancing the rigidity and strength of the winding portion. This structure mitigates deformation of the winding part during the winding process and alleviates issues such as wrinkles, poor alignment, and limited winding speed, thereby improving the quality and efficiency of electrode assembly production.

A coilbox is provided for winding a metal strip to form a coil and for unwinding the metal strip from the coil. In order to further develop a known coilbox in such a manner that the position of the coil is known at all times, in particular during its passive transfer from the winding station to the unwinding station, at least one additional roller rotatably mounted on the frame is provided.
