Ultrasonic splicing apparatus
Abstract
Abstract An apparatus of the type of advancing a thermoplastic sheet material from a source alternately over a number of paths to separate processing stations is modified to include a means for clamping, cutting, positioning and joining cut ends of the material for alternate advancement. The cutting and splicing mechanism comprises a first clamping means associated with each of the paths for clamping sheet material, a second clamping means positioned between the source of supply for the sheet material and the first clamping means and a cutting device associated with an ultrasonic welder positioned between the first and second clamping means. The controlled sequence of operation permits the cutting, overlapping, positioning and joining of adjacent ply ends of material to proceed automatically.
