ABSTRACT:
A method for removing waste pieces from a pre-cut sheet having cut portions and waste pieces therein, includes the steps of conveying the sheet and stripping needles along respective substantially parallel rectilinear paths and at the same rate of travel, impaling the waste pieces on the needles during the conveying step, and thereafter separating the waste pieces by moving the needles rotatively relative to the cut portions. Apparatus for performing the method includes conveyor means for the sheet and a link chain having the needles mounted on its links, for conveying the sheet and the needles in the aforesaid manner with the needles facing the sheet, means for moving the sheet laterally during such conveyance to impale it on the needles, and roller means mounting the chain at the upstream and downstream ends of the rectilinear path followed by the needles, to provide curved paths for the needles thereat and thereby effect the separation of the waste pieces at the downstream end and preimpalement thereof at the upstream end.
