Abstract
A single face splicer for creating a splice between a running web from a first source of single face material and a ready web from a second source of single face material to provide an uninterrupted supply of single face material to a double backer system in the manufacture of corrugated cardboard. The splicer includes an upper and lower bridge positioned above the first and second sources of single face material, and a splice head adjacent the upper bridge for creating the splice between the running web and the ready web. A drive system draws the running web through the splice head at an output speed which is greater than the speed at which the double backer system draws the running web from the splicer. The running web is deposited on an upper bridge supply belt which rotates at a speed which is slower than the output speed thereby causing the running web to accumulate on the upper bridge supply belt. As the splice is made, the double backer system draws from the accumulated storage on the upper bridge supply belt. To allow for pre-acceleration of the first and second supplies of single face material, the running or ready webs is deposited onto a first or second lower bridge supply belt which is rotating at a speed which is slower than the output speed of the first or second supply. An accumulation of running or ready web is created on the first or second lower bridge supply belt which allows for pre-acceleration of the first or second supply prior to the initiation of a splice.
