Ever-increasing productivity and waste reduction demands on the corrugator are prompting converters to place more requirements on their equipment. Also, their crews are increasingly required to not only operate equipment, but to trouble-shoot as well. The splicer has been designed to permit a change in roll stock width or grade without having to slow down to idle running speeds. During normal operation of the splicer, the paper unwinding from a roll stand passes up and through the splicer and into the single facer or glue machine. The paper passes through a splicer head and idler rolls, and around either a set of dancer rolls or through a driven carriage assembly. The dancer rolls (stationary type splicer) and the driven carriage assembly (driven type splicer) provide the method by which the paper from the newly spliced-in roll is permitted to run and accelerate up to the corrugator's running speed without having to stop or slow down the corrugator.
