ABSTRACT:
An apparatus and method for manufacturing partially cut (semi-converted) products in continuous roll form has input feeds for supplying a continuous web of material and a continuous transport web in parallel, feed rollers for incrementally advancing the two webs together to a cutting station where product units are partially cut in successive increments in a continuous strip, a scrap remover, and a station for winding up the cut product strip. The webs are unwound and the cut product strip is wound via dancer bars maintaining constant tension. The input webs have a width which is a multiple of the width of the product units so that multiple strips can be formed simultaneously. The invention is used to form semi-converted, micro diskette liners having connecting portions and indented cutouts marking the boundaries between units. The cutouts are overcut in one direction and also in an intersecting direction to obtain complete cuts despite slight variations in registration.
