ABSTRACT:
A method and apparatus provided for the automatic production of discrete cuffed sleeve blanks from distinct initial sleeve blanks and a continuous roll of knit cuffing material. The initial sleeve blanks are place end-to-end, a gap is introduced between them, and they are passed in a first direction with a first edge thereof parallel to the first direction. The continuous length of cuffing material is folded over to provide a double thickness having a first edge which is parallel to the sleeve blank first edge, the cuffing material and sleeve blank first edges are overlapped, moved together, and sewn to each other with an "over-edger" automatic sewing machine. The cuffing material is stretched just prior to being fed to the sewing machine, and is stretched again after sewing and severed from the rest of the roll. A driven roller includes non-rotatable washers having projecting portions engaging a blade of the cutting mechanism. The sleeve blanks formed are automatically picked up and moved in a second direction perpendicular to the first direction. For long sleeve finished blanks this is accomplished by utilizing a pair of projecting portions relatively rotatable with respect to each other to grasp the cuff of the finished blank betwen them, one of the projections having an air jet associated with it.
