The Smyth feeder transports the signatures through the openers in a shingled stream by means of geared belts. This unique opening system has the signatures traveling at 50% of the speed of the sewing machine at a 2:1 ratio. All other conventional automatic feeders cycle at a 1:1 ratio.
Example: Smyth sewing machine cycles at 100cpm, feeder cycles at 50cpm.
Other sewers cycle at 100cpm, feeder cycles at 100cpm
Contact time with the vacuum openers is longer and the special movement of the suckers (radial rotation) ensures a gentle and precise opening of the signature which is critical in the opening of lightweight and porous signatures. Other feeders use a 360-degree rotating sucker; This style 360-degree rotating sucker feeder is available as a lower cost option.
The lap opener works in conjunction with the 4th opener further enhancing the feeder’s ability to handle even the most delicate of signatures. The LAP opening device standard in all Smyth Book Sewers and is ready to work when programmed. No installation is required.
