Patent GB-1563545-A (GB)
Title: Patterning apparatus
IPC: D06B11/00
Filed: 1977-09-01
Abstract: Rams (1) which can be controlled individually or in groups each have a hollow space (10) extending over part of their length. These rams pass through a space (24) which can be subjected to overpressure for a printing substance containing ink or adhesive, for example. Each ram (1) can be displaced axially between an upper dead-centre point forming the rest position and a lower dead-centre point forming the working position. At the lower dead-centre point, the ram (1) is able to contact the material (3) or partially penetrate it. The material rests on a conveying device and is moved forwards by the latter in accordance with the pattern. The part of each ram (1) constructed in the manner of a hollow item is provided with at least one through-opening (110). This opening serves for allowing the hollow space (10) of the ram to be filled with a viscous printing substance during the ram advance through the printing-substance space (24); on the other hand, it is intended for producing the connection of the hollow space (10) of the ram to a source of compressed air at the lower dead-centre position of the ram (1). The discharge speed of the printing substance can be increased in this manner. This saves time in the case of patterns and allows a sufficient supply of the printing substance, e.g. printing paste, to thick-pile material. <IMAGE>
