A packaging machine for packaging goods in film packages, equipped with a device for receiving and holding a surface element roll, so as to process it in a packaging machine by unrolling the surface element and introducing the surface element into the packaging machine, comprising an axle to be incorporated into the surface element roll on its rotational axis of symmetry, wherein the axle is received in a swivel receiver, and the axle for unrolling the surface element is held with the swivel receiver in a roughly vertical alignment.

An embodiment of the present disclosure provides a non-stop constant-speed efficient winding machine for separator, and relates to the technical field of lithium ion cell manufacturing. The non-stop constant-speed efficient winding machine for separator includes a base plate, an electrode feeding mechanism, a winding mechanism, a separator cutting mechanism, and a separator compounding mechanism. The winding mechanism includes a winding head and three winding needles rotatably provided on the winding head. By additionally providing the separator compounding mechanism between the electrode feeding mechanism and the winding mechanism, thermal compounding of the separator is realized, and through rolling separator cutting of the separator cutting mechanism, the separator cutting is realized. The winding needle located at the winding position can adsorb a separator end after the cutting, and wind the separator end on an outer circumferential surface of the corresponding winding needle.

An arm for an unwinder for unwinding rolls is disclosed. The arm includes an axial engaging member for engaging the rolls. The axial engaging member has a shaft supported by at least two support bearings mounted on the arm, so as to rotate around a rotation axis. A brake is also provided, adapted to act on the shaft. The brake is at least partially arranged between the two support bearings.

A reel assembly includes a plurality of reels coupled to a reel support device. The reels are configured to rotate relative to the reel support device to dispense materials. The reel support device includes a first plate coupled to a second plate with fasteners that are coupled to first holes in the first plate and include a fastening portion received in second holes in the second plate. The fasteners are removably coupled to the second holes, such that an operator can rotate the first plate relative to the second plate by applying a lateral force to the first plate to remove the fastening portion from the second holes. The first plate rotates until the fastening portion is secured in a successive one of the second holes. During normal operation, an elastic element in the fasteners holds the first plate in position until the force is provided by the operator.

A material strip collection mechanism coiling fed material strip on a reel includes a vertically positioned reel bracket rotatable about a vertical axis between a first configuration and a second configuration. The mechanism further includes a first arm holding the reel and a second arm each rotatable to drive the reel and coil the material strip on the reel. With the reel bracket in the first configuration, the first arm is in a material strip collection position to allow the material strip to be coiled on each empty reel held by the first arm to form a full reel, while the second arm is in a standby position to allow the full reel held by the second arm to be replaced with a new empty reel.

An arm (5; 5A, 5B) for an unwinder (1) for unwinding rolls (B) is disclosed. The arm includes an axial engaging member (11) for engaging the rolls (B). The axial engaging member (11) has a shaft (11.3) supported by at least two support bearings (15, 17) mounted on the arm (5; 5A, 5B), so as to rotate around a rotation axis (A-A). A brake (23) is also provided, adapted to act on the shaft (11.3). The brake (23) is at least partially arranged between the two support bearings (15, 17).

An apparatus to launch, retrieve, and store a recreational floating mat is described. The apparatus can provide the advantages of helping to ease the potential difficulties associated with launching, retrieving and storing recreational floating mats from dock side, pool side or from a floating vessel such as a boat or floating dock.

A transfer apparatus for a material for an electrode according to an embodiment of the disclosed technology includes an apparatus body; a gripping device configured to grip a reel wound around a current collector; a first moving device connected to the gripping device and the apparatus body and configured to move the gripping device; a position changing device configured to rotate the reel when the reel is seated; and a first discharge device disposed on one side of the apparatus body and configured to discharge the reel to the outside of the apparatus body when the rotated reel is seated.
