750,065. Travelling-band filters; presses for separating liquids from solids. CELANESE CORPORATION OF AMERICA. May 16, 1952 [May 16, 1951], No. 22485/54. Divided out of 749,996, [Group IV (a)]. Class 46. Apparatus for the production or treatment of artificial staple fibres comprises means for cutting a tow of continuous filaments into staple fibres, means for delivering the staple fibres in admixture with a liquid to a receiving tank 122, Fig. 3, having an opening 164 in its floor, a perforated belt 161 beneath the opening, and means (not shown) for driving the belt whereby staple fibres and the liquid fed as a mixture to the tank 122 flow on to the belt and are separated thereby The fibres 166 on the belt may be compacted and have further liquid removed from them by a positively-driven weighted roller 167, preferably pivoted at 169 so as to rest freely on the fibres. The tow 53 of continuous artificial filaments, Fig. 2, may be guided to a pair of nip rolls 115 by a forwarding device 112 and rollers 113 and 114. The nip rolls are close to (preferably within 12 inches of), a cutter 116 from which chips 117, each comprising a number of staple fibres packed together, are delivered to an inclined trough 118 up which the chips are conveyed, and in which. they are disintegrated into individual fibres, by liquid introduced at high velocity through a nozzle 119 (all as described in Specification 750,066, [Group IV (c)]). A pair of cutters 116 may be provided, each with its nip rolls 115 and guide roller 114, so that one may be in use while the other is serviced. The size of the opening 164 may be controlled by a floor 165 which can be moved back and forth. The belt 161 may have vertical side walls 162. Specification 750,066, [Group IV (c)], also is referred to.
