A feeding path (P) is provided for rolls (R, R1) to be closed and a closing station placed along that path. Two rollers (15, 17) form a cradle (19) for receiving the rolls (R, R1). A closing member (21) is provided to close a tail end (L). A rotating assembly (23) rotates around an axis (A-A) transverse to the feeding path and has groups (27A, 27B, 27C) of arms (28A; 28B, 28C) arranged with respect to one another angularly displaced around the rotation axis of the rotating assembly (23). Each arm has a front part (29) to eject a roll (R, R1) from the cradle (19) and a back part (31) to prevent a subsequent roll entering the closing station until the ejection of a roll from the cradle (19). Rotation of assembly (23) causes closed roll ejection and allows a subsequent roll (R1) to enter and be closed.

A dunnage production system for producing coiled strips of dunnage includes a supply of strip-like dunnage, a coiler adjacent the supply and rotatable about a coiling axis for coiling a strip of the strip-like dunnage into a coil having a coiled configuration, and a tube aligned with the coiling axis. The tube has an internal diameter sized to receive the coil from the coiler in a discharge direction parallel to the coiling axis. The tube is capable of holding at least one coil in its coiled configuration until it is removed from the tube.

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.

Provided are a winding mandrel, a winding machine, and a battery cell winding method. The winding mandrel includes a first connecting member and a second connecting member configured to be combined with the first connecting member. The second connecting member and the first connecting member are arranged coaxially, and length of the combined first connecting member and second connecting member is greater than length of the first connecting member or the second connecting member. Changing a structure of a winding mandrel improves stiffness of the winding mandrel and improves the efficiency and quality of a winding operation.

Techniques for processing a web with a laser are provided. In an example, an apparatus for processing web material can include multiple processing stages and a laser assembly. Each of the multiple processing stages can be configured to process a moving web of material along a web path. The laser assembly can be configured to process the moving web of material with a laser at a first stage of the multiple stages. The laser assembly can include a laser configured to generate a laser beam, a gimble assembly configured to direct the laser beam along a cut path at a position of a web path of the moving web of material, and a servo driven mirror assembly configured to provide an adjustable field of view for the laser stage at the position of the web path.

A cradle system for a rewinder machine shapes a rolling surface for a core and includes at least two portions arranged to define the rolling surface. The at least two portions are each movable in a predetermined position so as to vary the profile of the rolling surface and/or the length of the rolling surface as a function of their assumed positions.

The invention comprises a carpet wrapping apparatus. The apparatus comprises a pair of rotatable rollers for supporting a roll of sheet material and for rotating the roll of sheet material supported thereon and a vertically extending curtain disposed adjacent and spaced from the roll of sheet material so that there is a horizontal gap between the curtain and the roll of sheet material when supported on the rollers. The apparatus also comprises a source of pressurized air directed toward the curtain and a plastic film dispenser disposed above the rollers for dispensing a plastic film between the curtain and the source of pressurized air so that the pressurized air blows the plastic film toward the curtain and into the gap. A method of wrapping a roll of carpet with a plastic film is also disclosed.

A winding device for winding a web-shaped material, preferably a plastic film, has a reel for receiving the web-shaped material, a contact roller for feeding and pressing the web-shaped material against the reel, a device for rotationally driving a still empty reel, and a device for feeding the still empty reel to the contact roller. The device for rotationally driving the still empty reel and the device for feeding the still empty reel to the contact roller can act simultaneously on the still empty reel.

A motorization group of reels in a machine for winding plastic film onto bobbins, wherein at least two spindles are positioned on a rotating plate around a central shaft constrained to a frame of the machine, a motor being operatively coupled to each of the spindles, in the motorization group each of the motors being constrained to the frame and connected to each of the spindles by a belt transmission which comprises a central deflector unit aligned with a central shaft outside the frame, toothed belts connecting the central deflector unit, on the one hand, to the spindles, and on the other hand, to the motors.

An accompanying squeezing unit in a machine for winding plastic film onto bobbins, in which at least two spindles are positioned on a rotating plate around a central shaft constrained to an upright of the machine, the group including an accompanying squeezing roll situated on a lever mechanism which is selectively actuated to rotate-oscillate by actuators in order to maintain the squeezing roll positioned on a film in the final winding onto a bobbin positioned on one of the spindles, the lever mechanism being activated when the plate carrying the spindles is rotated to discharge a finished bobbin. The lever mechanism in the group includes two first levers and two second levers articulated relative to each other.
