ABSTRACT:
A splicer for use with machines which receive and handle a web of paper or other suitable material supplied in a continuous length. The paper is supplied from a pair of rolls and when one roll is exhausted, the other one is substituted. A movable splicer assembly is disposed adjacent a paper supply roll and which includes an idler roll, a paper stop device, a severing device and a splice sealing roll. When the assembly is disposed adjacent the nearly exhausted paper roll, the stop device is actuated to hold the outgoing web from moving, regardless of the existence or adequacy of a roll brake. When the assembly is disposed adjacent the spent roll, the stop device positively holds the paper for lead-edge cutting and trimming during set-up and to keep the paper in place until the splice is made. The splice sealing roll has provisions to guide a cutting tool for said lead-edge forming of the fresh web, and also for optimally locating the lead edge. An idler roll is disposed at the discharge end of the splicing area, with the idler roll cooperating with a tensioned dancer or accumulator roll to maintain proper tension on the paper web at all times. The idler roll is convertible to a capstan drive roll when the splice has been made to thereby increase the paper tension upstream and assist in acceleration of the web from the fresh roll up to normal speed.
