ABSTRACT:
An apparatus for the continuous, automatic manufacture of individual shoe covers includes a supply of two continuous webs of material, a device for advancing each of the two webs through the apparatus, an adhesive applicator for applying an adhesive at longitudinally spaced increments to at least one of the webs, a pressing station where the webs are pressed together to form adhesively joined segments at the longitudinally spaced increments, a hole producing station where holes are made in the adhesively joined segments, a second pressing station where the webs are again pressed together, stations for sewing one longitudinal edge and selected portions of the other longitudinal edge together between adjacent adhesively joined segments, and a severing station where the webs are cut through the adhesively joined segments to form individual shoe covers. The hole producing station may include a rotatable member having a number of pins extending from it. The rotatable member is driven so that the pins make holes in the webs through the adhesively joined segments. The rotatable member may be driven in synchronism with the adhesive applicator in order to produce holes only at the desired locations, i.e., at the adhesively joined segments. The pins are advantageously heated to reduce the amount of adhesive sticking to the pins and to enhance their ability to produce holes.
