Intermittent web feeding apparatus |
摘要 |
An intermittent web feeding apparatus for intermittently feeding fixed length of a web of material during one cycle of a feeding operation by the cooperative operation of a pair of feed rollers for unwinding a web of material from a roll of web material and feeding the web of material to a web processing machine such as a bag-forming and packing machine, and for feeding the web of material to a processing position within the web processing machine, is disclosed. The intermittent web feeding apparatus is equipped with a single servomotor for driving the feed rollers through means of a first transmission mechanism, and the feeding units through means of a second transmission mechanism. The second transmission includes a one-way clutch for delaying the stoppage of the feeding units for a suitable period of time relative to the feed rollers so that the portion of the web of material extending between the feed rollers and the feeding units is kept in a moderately taut state when the web feeding operation is interrupted.
