Abstract
An infeed mechanism coacts with a splicer mechanism for splicing successive rolls of web and for feeding the continuous web thus obtained into a rotary press or the like via a web storage mechanism, which normally stores therein a predetermined length of the web for delivery to the press or the like during splicing operation. The infeed mechanism includes a pair of roll holder arms carrying on their opposite ends an old web roll, from which the web is being delivered to the press or the like, and a new web roll to be spliced to the old web. Toward the end of the web delivery from the old web roll the roll holder arms are turned through a preassigned angle, with the result that the web from the old web roll travels close to the periphery of the new web roll. Then the new web roll is revolved about its own axis until an adhesive region thereon comes opposite to the old web. Then, with the rotation of the old web roll arrested, a brush of a retractable splicer mechanism presses the old web against the adhesive region on the new web roll. Preferably an excess length of the old web behind the adhesive region is subsequently cut off by a cutter included in the splicer mechanism. Then the…
