Abstract
To facilitate threading-up of apparatus for the treatment of a plurality of separate filaments moving in a tortuous path, a flexible element such as an endless rubber band is arranged to follow a path parallel to but not coincident with the filaments and is provided with hooks or other means to which the ends of filaments can be temporarily attached during threading-up. Preferably the filaments are guided by grooved rollers at one end of which is the flexible band. The filament ends are temporarily attached to one of the hooks thereon and upon emerging from the apparatus are detached therefrom and engaged in the appropriate grooves in the guide rollers. By suitable arrangement of filament guides, engagement of the filaments in their correct grooves is automatic. A number of different filament ends <PICT:0756480/IV(a)/1> <PICT:0756480/IV(a)/2> <PICT:0756480/IV(a)/3> may be attached to different hooks successively to expedite the completion of threading up. As shown, filaments from the spinning assemblies 11-11c pass over and under grooved rollers 26, 27 in treating baths 21 and a drying compartment 22 having convector heaters 29, 30, to a winding device 36. Upper rollers 26 are driven. An endless rubber band 38 passes round one end of each roller following the same path as the filaments, and returns over idler pulleys 39, 41. The rubber band 38 has a series of pins 43, Fig. 4, projecting from one side, the pins having enlarged heads 44. For threading up, filaments from spinning assembly 11 are led through gap 23 in comb guide 24 and are attached to one of the pins on the endless band 38, which threads the filaments through the apparatus, whereupon they are manually detached from endless band 38, guided through gap 31 in comb guide 32, over driven roller 33 to winding device 36. The pull on the filaments automatically transfers them across the rollers 26, 27 until they fall into their correct set of grooves. Filaments on the second spinning assembly 11a are guided through the second gap in comb guide 24 and attached to a pin on the endless belt and this may be done whilst the first filament is still being guided through the apparatus, and so on until all filaments are running through. Specification 744,319 is referred to.ALSO:<PICT:0756480/IV(c)/1> <PICT:0756480/IV(c)/2> <PICT:0756480/IV(c)/3> To facilitate threading-up of apparatus for the treatment of a plurality of separate filaments moving in a tortuous path, a flexible element such as an endless rubber band is arranged to follow a path parallel to but not coincident with the filaments and is provided with hooks or other means to which the ends of filaments can be temporarily attached during threading-up Preferably the filaments are guided by grooved rollers at one end of which is the flexible band.
