  • Patent number: 4481006
    Abstract: A length of woven plastic fabric in tubular form is advanced from a source of supply while telescoped over a separator plate which maintains the two plies of the tubular stock in separated relation. A heated knife blade aligned vertically with the downstream end of the separator plate is reciprocated vertically to sever the tube stock into bag blanks. The severed edges on the upstream side of the heated knife remain separated rather than being heat sealed together by the heated blade. The severed blank is impaled on needles mounted on an endless chain which conveys the blanks laterally through a sewing machine and/or a sealing mechanism for securely closing one end of the blanks. Thereafter successive blanks are conveyed to a stacking device which disengages the blanks from the needle chain and stacks them horizontally one upon another.
