Abstract
An automated sleeve transfer apparatus and method adapted to receive continuous webs of material including pairs of left and right sleeves alternating between cuff-to-cuff and shoulder-to-shoulder relation and having a die cutting mechanism for receiving the pairs of sleeves from the webs is disclosed having a circular wheel having rotatable vacuum plates on its circumference for carrying pairs of sleeves along a circular path to a transfer point, a conveyor for transferring successive severed pairs of cuff-to-cuff sleeves from the die cutting mechanism to the vacuum plates on the circumference of the circular wheel, a mechanism within the circular wheel for rotating the vacuum plates to turn each sleeve end for end to rearrange the sleeves from cuff-to-cuff to shoulder-to-shoulder relation while moving along the circular path before said transfer point, a second conveyor for receiving successive severed pairs of shoulder-to-shoulder sleeves from the die cutting mechanism and for conveying the sleeves in spaced relationship along a linear path tangent to the circular path at said transfer point, and a control of the vacuum supplied to the vacuum plates so that successive rearranged…
