ABSTRACT:
A non-alternating lap splicing apparatus for successively splicing rolls of web material is enclosed in a bifurcated housing with a separate access door for each of two compartments therein. There is a driven spindle in each of the compartments, each for supporting a stock roll of web. There is a separate film inlet path for each of the stock rolls. An oscillator assembly having a cutting knife and an ultrasonic horn means is mounted in the housing. The web outlet path is through the oscillator assembly. When one of the rolls is nearly spent, that roll is automatically stopped and the web is cut by the knife to create a trailing end. The oscillator assembly then pivots to align with the film inlet path for the stock roll within the other compartment. The lead end of the new stock roll is automatically positioned under the trailing end of the spent stock roll and the ultrasonic horn bonds the webs together. The overlapping lap of the splice is always trailing and on the same side of the web. The compartment containing the spent stock roll can be manually reloaded with a new stock roll in safety. When the operator opens the access door of one of the components, all components contained within that compartment are automatically de-energized.
