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.

Provided is a glass winding system configured to switch between a breaking mode and a winding mode in which glass is wound with an interleaf to form the glass roll. Furthermore, a system for forming glass rolls includes a glass ribbon supply system (100), a cutting system (200) configured to cut the initial glass ribbon into a first glass ribbon and a second glass ribbon, a first glass winding system (400) configured to wind the first glass ribbon to form a first glass roll, and a second glass winding system (300) configured to switch between a breaking mode and a winding mode.

A core prevents a battery separator wound therearound from moving and becoming misaligned on an outer circumferential surface of the core in a widthwise direction of the core. The core allows a separator to be wound around the outer circumferential surface thereof and is made of resin. The core includes a groove formed on the outer circumferential surface thereof, the groove extending in a direction substantially equivalent to a circumferential direction of the outer circumferential surface.
