ABSTRACT:
An anvil for our ultrasonic textile slitting apparatus comprises an elongated, flat, substantially rectangular, housing in which two pistons are disposed for motion relative to one another along the longitudinal axis of the housing. A first piston, responsive to fluid pressure, is urged against the force exerted by springs into motion toward the second piston for causing the second piston, which is provided with a slitting implement, to be urged toward contact with the output surface of an ultrasonic horn. Further, springs are interposed between the first and the second piston for urging the pistons apart, but becoming compressed responsive to such fluid pressure. The combination of fluid pressure and springs causes the slitting implement to be kept in continuous contact with the horn despite the very high acceleration forces manifest at the horn output surface. In addition, the springs provide vibratory isolation from the vibratory energy of the horn. The flat anvil construction permits a plurality of anvils to be disposed in close proximity to one another for slitting textile material into narrow strips.
