Abstract
A process for splicing cut ends of a continuous strip of packets or bags used to hold bulk material. The steps of the process include forming a continuous strip of packets from packaging material and filling the packets with bulk material. The edges of the packaging material are sealed to form individual packets of the continuous strip such that adjacent packets share a common sealed area of packaging material. Openings are then formed in the common sealed areas between the adjacent packets. The continuous strip is then cut entirely across the common sealed area of the packets at two separate locations on the continuous strip to form cut ends such that each of the cut ends of the continuous strip contains an opening in the common sealed area. Without using splicing tape, the two cut ends of the continuous strip with openings are spliced together such that the openings in the two cut ends overlap. The splicing process can be accomplished by ultrasonic welding, impulse splicing or other processes. Also disclosed is equipment for the splicing processes.
