ABSTRACT:
Transfer of a portion of a first material from a position where it is removably adhered to a carrier means to a sheet means is facilitated by intermittently blowing a burst of compressed air between the carrier means and the sheet means after the first material has been brought into contact with the sheet means between a pair of reciprocating dies and is being separated therefrom. With the carrier means moving in one direction and the sheet means moving in an opposite direction the air, which may be warmed, is blown in the direction of the carrier means against the direction of the sheet means so that it exerts a separating effect between the two at their interface. The air may be conveyed through members which serve as guides on one or both sides of the dies. In addition, at least one of the die parts can be provided with a vacuum means for intermittently drawing one of the carrier means or sheet means thereagainst during transfer. An ultrasonic vibrating means which is effective to vibrate the ambient air between the carrier means and the sheet means may be provided in lieu of or in addition to the bursts of air.
