First Claim
1. A single face splicer for supplying a running web of single face material to a double backer system said splicer comprising:
- first and second sources of single face material, said first source providing said running web of single face material and said second source providing a ready web of single face material, said single face material including a fluted web and a backing adhered to said fluted web;
an exit bridge positioned downstream from said first and second sources of single face material for accumulating said running web;
a splice head positioned intermediate said exit bridge and said first and second sources of single face material for creating a splice between said running web of single face material and said ready web of single face material;
a drive system for drawing said running web through said splice head at an output speed which is greater than a double backer speed at which the double backer system draws said running web from said splicer;
an exit conveyor operably connected to said exit bridge,wherein said drive system is adapted for depositing said running web onto said exit conveyor at said output speed, and wherein said exit conveyor is adapted for movement relative to said exit bridge at an exit conveyor speed which is slower than said output speed to cause said running web to accumulate on said exit conveyor to provide an uninterrupted supply of said running web to the double backer system as said splice is created; and
an entrance bride positioned intermediate said exit bridge and said second source of single face material for accumulating said ready web.

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.

12. A method of supplying single face material to a double backer system comprising:
-
providing a single face splicer, said splicer comprising; first and second sources of single face material, said first source providing a running web of single face material and said second source providing a ready web of single face material, said single face material including a fluted web and a backing adhered to said fluted web; an entrance bridge and an exit bridge positioned downstream from said first and second sources of single face material, said entrance bridge positioned intermediate said exit bridge and said second source of single face material; a splice head intermediate said exit bridge and said first and second sources of single face material for creating a splice between said running web and said ready web; a drive system for drawing said running web through said splice head at an output speed which is greater than a double backer speed at which the double backer system draws said running web from said splicer; an entrance conveyor operably connected to said entrance bridge adjacent said second source of single face material; and an exit conveyor operably connected to said exit bridge, wherein said entrance conveyor is adapted to receive said ready web at an input speed from said second source of single face material, and wherein said entrance conveyor is adapted for movement relative to said entrance bridge at an entrance conveyor speed which is slower than said input speed to thereby cause said ready web to accumulate on said entrance conveyor to allow for pre-acceleration of said second source of single face material prior to initiation of said splice, and wherein said drive system is adapted for depositing said running web onto said exit conveyor at said output speed, and wherein said exit conveyor is adapted for movement relative to said exit bridge at an exit conveyor speed which is slower than said output speed to cause said running web to accumulate on said exit conveyor to provide an uninterrupted supply of said running web to the double backer system as said splice is created; moving said exit conveyor at said exit conveyor speed; operating said drive system to deposit said running web onto said exit conveyor thereby causing accumulation of said running web on said exit conveyor, said accumulation providing an uninterrupted supply of said running web as said splice is created; moving said entrance conveyor at said entrance conveyor speed; pre-accelerating said second source of single face material to supply said ready web onto said entrance conveyor prior to initiation of said splice; and initiating said splice when said first source of single face material is nearly exhausted, whereby after said splice is created said second source of single face material provides said running web and said first source of said single face material provides said ready web. - View Dependent Claims (13, 14, 15)
