A splicer is used in a corrugated cardboard production line. The splicer has a pair of pivotal levers having opposing jaws which open and close responsive to a pivoting of the levers. The faces of each of the jaws have a pair of pads for enabling a passage of a web of corrugated cardboard when the jaws are opened and for gripping the web when the jaws are closed. A guillotine blade is positioned between the pairs of jaw pads to grip the web when the jaws are closed. A pair of brake shoes are positioned downstream from the jaws for holding the web while the brake shoes are closed. The jaws, blade, and brake shoes are operated in a sequence wherein (a) the web is gripped by the jaws and held by the brake shoes, (b) the blade cuts the web, (c) the jaws open to release their grip while the brake shoes maintain their hold (d) the jaws close to regrip the web, (e) the blade again cuts the web for a second time, and (f) abutting ends of the web are spliced together while the web is held by the brake shoes and gripped by the jaws. Immediately downstream from the splicer, a store of the web is accumulated before the cutting sequence. This stored web is paid out of the store during the cutting sequence so that downstream production line is not interrupted by the cutting sequence. |
