Abstract
Abstract A CONTINUOUS ELASTIC BAND IS DRAWN BY FEED ROLLERS IN STRETCHED CONDITION ACROSS A WORK SURFACE AND IS SEWN TO GARMENTS ON THW ROK SURFACE. A PILOT PHOT-CELL DETECTS THE TRAILING EDGE OF A GARMENT JUST BEFORE IT ENTERS THE FEED ROLLERS AND PRODUCES A SIGNAL WHICH SETS A SECOND PHOTO-ELECTRIC DEVICE. A PNEUMATICALLY OPERATED CUTTING DEVICE POSITIONED IMMEDIATELY AFTER THE FEED ROLLERS CUTS THE ELASTIC BAND BETWEEN GARMENTS WHEN THE SECOND PHOTO-ELECTRIC DEVICE WHICH IS ADJACENT THE CUTTER BLADE DETECTS A GAP BETWEEN GARMENTS. THE CUTTING DEVICE WILL NOT OPERATE UNLESS THE SECOND PHOTO-ELECTRIC DEVICE HAS BEEN SET BY A SIGNAL FROM THE PILOT PHOTO-CELL.
