ABSTRACT:
A manufacturing machine operating at high speed and using a feed system with suction cups can be fitted with an air delivery system in which the single suction cup is mounted directly to a three-way valve affording a first passage open to the cup, a second passage coupled to a vacuum pump and a third passage connected to a source of compressed air; the second and third passages can be connected in alternation to the first passage, in such a manner that the cup will release swiftly and positively as suction generated by the vacuum pump is neutralized by the rush of air.
