ABSTRACT:
An apparatus and method for introducing a pleat into an advancing folded-over film web is provided which utilizes air under low pressure to separate the opposing faces of the web prior to the pleat being made. By unblocking the faces of the folded-over web, the web may be readily advanced and pleated without hang ups, misalignment, or tearing of the web. The apparatus includes a pair of substantially aligned and spaced-apart receiving plates over which opposing faces of the film web pass, a generally circular wheel positioned between the receiving plates and extending into the space therebetween for forming a pleat in the folded-over film, and an air passage positioned between the receiving plates for directing a flow of air between the opposing faces of the film web to separate the opposing faces of the web prior to passing over the receiving plates.
