Packaging system producing tubular skins for sausages - uses speed regulator to ensure smooth removal of one tube and gathering of new tube

摘要

The axial movement for drawing off one tubular skin from a gathering tube and gathering a new tube onto another gathering tube fixed to the first is kept at a constant speed through a closed regulating circuit. A speed sensor (46, 48, 50) attached to the frame (10) or slide carriage (12) interacts with a setting member in the energy supply line of the carriage drive (16,20) to regulate the speed. The speed sensor has a rotatable signal transmitter (46) set on the slide carriage and driven by a pinion (48) engaging with a toothed rod (50) on the frame (10). ADVANTAGE - The tubes formed and removed are uniform without uneven gathering.
