A roll transfer assembly for a web processing system includes a support beam configured to be mounted to a frame. The assembly includes a segmented roll assembly mounted to the support beam and includes a first and second end segments and a central segment positioned between the first and second end segments. The assembly includes a first transfer roll positioned between the first end segment and the central segment and a second transfer roll positioned between the second segment and the central segment. The assembly includes an actuation assembly that includes a first drive system configured to translationally move the first transfer roll and the second transfer roll. A second drive system is configured to move the roll transfer assembly relative to the frame.

A reel carrier that includes a pallet having a platform bound by a frame and a shaft. The carrier includes a reel that is supported on the shaft. The reel includes a round drum rotatable about the shaft, wherein the rotation may be in a forward and/or a reverse or backward rotational direction. The carrier also includes a motor operably coupled to cause rotation of the drum and may be further operably coupled to cause deployment and/or retraction of one or more wheels included with the pallet, wherein the motor also controls locomotion of the one or more wheels.

A winding device including: a merging equipment, for merging a passing first diaphragm, a passing cathode pole piece, a passing second diaphragm and a passing anode pole piece to form a combined material strip; a first pole-piece-processing equipment, for cutting off the passing cathode pole piece, separating from each other a first upstream cut-off end and a first downstream cut-off end, and connecting them with a tape; a winding equipment, including a turret and at least two winding needles, the turret driving each of the winding needles to pass by a first station and a second station sequentially; and a guiding roller and a cutting-off equipment.

A winding device includes: a first unwinding equipment, a second unwinding equipment, a third unwinding equipment and a fourth unwinding equipment, respectively configured for outputting a first diaphragm, a cathode pole piece, a second diaphragm and an anode pole piece; a merging equipment, configured for merging passing material strip layers; a pole-piece-inserting equipment, configured for cutting off the passing cathode pole piece, and transporting a starting end of the cathode pole piece downstream; a winding equipment, including a turret and at least two winding needles, the turret is adapted to drive each of the winding needles to pass by a first station and a second station sequentially; and a guiding roller, the layers of material strip located between the first station and the second station winding through the guiding roller.

An apparatus (100) for making coils, preferably for electrochemical cells intended for battery production, comprises a feed unit (2) configured to feed at least a first strip-shaped article (N1) intended to form a first coil (B1) and a second strip-shaped article (N2) intended to form a second coil (B2), a winding unit (1) comprising a plurality of winding heads (10) including at least a first winding head (11) configured to wind the first strip-shaped article (N1) and a second winding head (12) configured to wind the second strip-shaped article (N2) and at least one movement device (3) of said winding heads (10) configured to move said first winding head (11) and said second winding head (12). Said first winding head (11) and said second winding head (12) define respective winding axes (X1, X2) substantially parallel to each other. Said winding unit (1) is configured so as to define a separation plane (P), said separation plane (P) being substantially perpendicular to said winding axes (X1, X2) and being positioned so that said first strip-shaped article (N1) and said second strip-shaped article (N2) are located one on one side and the other on the opposite side of said separation plane (P) at least at said first winding head (11) and said second winding head (12).

A winding apparatus configured to wind a sheet material is provided. The apparatus includes a belt configured to contact an outermost circumferential surface of a rolled material to rotate the rolled material, and a belt driving device configured to rotationally drive the belt. The apparatus is configured such that a radius of curvature of a portion of the belt configured to be in contact with the rolled material increases in conjunction with an increase in a diameter of the rolled material. The rolled material is the sheet material wound to form layers in its thickness direction. The sheet material is a flexible sheet-shaped member.
