ABSTRACT:
An apparatus and method of forming individual sealed plastic bags from a continuous web of a layflat tubular film material wherein the individual plastic bags, subsequent to the formation of bag seals and the separation of the film web into individual plastic bags, are intermittently and sequentially conveyed through a cooling zone which will allow for the cooling of the bag seals. Thereafter, the bags are serially conveyed to a bag stacking arrangement incorporating a stacker foot which will position the first or bottom bag of a stack being formed on a vacuum box which retains the bag in a fixed position and with subsequent bags being superimposed on preceding deposited bags and sealed thereto through the intermediary of heated needles depending from the stacker foot which will penetrate and concurrently seal the bags together at predetermined locations. The forward portion of the bags of the stack is supported on a continuously-driven conveyor belt which, when a predetermined number of bags have been stacked, will cause the bags to be conveyed into a further storage conveyor.
