Abstract (en)
[origin: US4374575A] A winding machine for winding up into rewind rolls a plurality of strips cut from an elongated web includes contact drums respectively bearing against the rewind rolls, the contact drums being independently arranged for independently exerting pressure against their rewind rolls for independently maintaining the necessary gap values between them and the periphery of the main drum about which the strips are partially looped upon entering the machine. Detecting devices associated with pairs of support arms provided for the contact drum operate a motor associated with each of the support arm pairs for each rewind roll for simultaneously rotating a pair of spindles on the support arms so as to pivot them away from the centerline of the machine when the extent of the aforementioned gap at each contact drum is reduced below a desired minimum.
