ABSTRACT:
A continuous web converting machine is supplied with web material from a spider wheel unwind stand having a shiftable wheel axis. Movement of the spider wheel axis is regulated by a double acting fluid cylinder for controlled force application of the working web supply reel against a closed circuit pulling belt. Depletion of the working reel is detected by a limit switch actuated by contact with the shift carriage. Upon working reel depletion, the pressure bias on the fluid cylinder is reversed and the shift carriage retracted to free the working reel from contact with the pulling belt. Thereafter, the spider wheel is rotatively indexed 120.degree. to align a full working reel and the shift carrier advanced until the full working reel bears into the pulling belt with the desired pressure.
