Abstract
A device for changing reels of strip material on a production machine, whereby a traction device unwinds a first strip off a runout reel on a supporting spindle and feeds it to the production machine along a given path; a standby reel is supported on edge on a saddle defined by two rollers; and a swing arm supports a powered disk with suction cups and a locating spindle. As the first strip runs out, the standby reel is made integral with the disk by the suction cups; the disk is accelerated so as to wind a second strip, identical to the first, off the standby reel and through a guide device by which the second strip is inserted into the traction device; and the swing arm loads the standby reel on to the axially-sliding supporting spindle in place of the empty reel.
