ABSTRACT:
The invention relates to a tenter frame for treating web materials such as woven or knitted fabrics, film or the like, to apparatus for removing a web from a tenter while controlling the web and to a process for removal of a web from a tenter. A pair of endless opposed tenter chains having a plurality of pins thereon engage opposite edges of the web material for holding it as it is treated on the tenter frame. Pinned rolls are provided for engaging and transferring the web material from the pins of the tenter frame with the web taken off of the tenter chains without loss of control over the web. A cutter unit is also provided for trimming the edges from the web after it has been removed from the tenter chain, and while the web remains under control of the pinned rolls, after which trimmed edges are automatically removed from the pins for discarding.
