ABSTRACT:
Flat tubular web is supplied from a textile finishing machine and cooled down by jets in a cooling unit to the room temperature or thereunder and dried in the process. The web is then passed by a laying unit onto a table in the form of a folded stack. The laying unit comprises a reciprocating carriage that is moved by an endless chain with a sliding member thereon running in a slide on the carriage. The carriage is supported on parallel rods. There is a tenter placed inside the web tube and over two rotating bars in the carriage. The web passes between the bars on its way to the stack. The bars are driven by a stationary double chain acting as a rack and by sprocket wheels which are connected with the bars by freewheels such that the bars are driven alternately as the carriage is reciprocated. When the stack has grown to the desired height the table operates a limit switch for operation of a clearing conveyor for removing the stack sideways.
