Filed: 1932-05-07
Abstract: <PICT:0391612/IV/1> <PICT:0391612/IV/2> In a machine for the dyeing and other liquid treatment of yarns, rovings, fabrics in rope form &c. in which the material travels in a spiral or helical path round a drum or roller immersed in liquid, the drum or roller A is of such a construction that it tends to float in the liquid and is mounted in such a manner that it may move in a vertical plane, by which means tension on the material is reduced.  The drum is preferably constructed of a hollow central portion A with ends a of larger diameter to carry a number of bars B, so forming a cage-like structure giving free access to the material.  The buoyancy of the drum may be adjusted by partly filling the interior with oil, water, mercury, &c. Alternatively, the centre portion of the drum may be constructed of wood or other light material.  The drum is either provided with a central spindle a<1> which moves in vertical slots in the depending supports C, or it is mounted loosely on a fixed rod which passes through a tube of considerably larger diameter passing axially through the drum.  The material is guided during its several passages by means of a comb E having eyes e, hooks, teeth or indentations.  The material enters the machine through a main guide e<1> and after passage through the liquid is guided by means of a roller e<2> to nip rollers G by means of which it is drawn through the machine, the drum running free.  The drum may, however, be driven as by means of a belt from the nip rollers in order still further to reduce the tension on the material. More than one drum either in line or side by side may be employed in a single tank, and the latter may be interchangeable.
