SYSTEEM VOOR AUTOMATISCHE AANSLUITING TUSSEN OPEENVOLGENDE HASPELS MET PAPIERBANEN.

摘要

A continuous paper supply is provided from alternative supply rolls by momentarily stopping the paper being supplied and adhesively joining the leading edge of a new supply severing the old supply and accelerating the new supply. A loop of paper is paid out during the momentary stoppage of the acceleration of the new supply and is thereafter recovered in preparation for the next changeover. An idler roller senses tension in the paper and generates a signal to the supply. The idler roller is capable of skewing to equalize tension across the paper.
