Disclosed is a method and apparatus for winding cargo straps. The apparatus comprises a base, connectors adapted to secure the base to a portion of a vehicle and a motor supported from the base. The apparatus further comprises a shaft extending from and rotated by the motor, the shaft having a plurality of mounting locations therealong, a guide flange secured around the shaft at one of the plurality of mounting locations and a guide cap secured to a distal end of the shaft. The method comprises securing the base to a vehicle, locating a guide flange at one of the plurality of mounting locations, securing a distal end of the strap to the shaft, locating the guide cap to the distal end of the shaft and actuating the motor to rotate the shaft thereby winding the strap thereon.

The present disclosure relates to a device for assisting in the folding and rolling of a tarp. The device comprises a frame and a tarp rotator. The frame may be adapted for mounting on the edge of a flatbed trailer, for example mounted on a rub rail on the edge of the trailer. The frame includes releasable attachments for supporting the tarp rotator offset from the edge of the trailer and allowing rotation of the tarp rotator. A tarp may be prepared by producing a fan fold configuration and inserting into a receiving gap in the tarp rotator. The tarp rotator may then be rotated to wind the tarp around the tarp rotator. The tarp rotator with rolled tarp thereon may then be released from the frame and transferred to the trailer whereupon the tarp rotator is removed from the tarp, thus producing a completed rolled tarp ready for storage.

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.
