Title: Improvements in the treatment of artificial filaments, threads, films and the like
IPC: D06M15/05
Filed: 1934-05-22
Abstract: Cellulose derivative filaments, threads, fabrics, films, and the like are impregnated by treatment in the swollen condition with a viscose solution.  The swelling agents used may be such as have a precipitating action on the viscose, for example, alcohol or diluted acetic acid, or a regenerating action, such as concentrated hydrochloric acid.  The viscose, which advantageously is of low concentration, for example, up to 2 or 4 per cent strength, may be applied by soaking, spraying, printing or the like.  The viscose may contain additions such as glycerine, glycols, oleaginous or other softening agents, fillers, pigments, colours, or the like.  The cellulose is regenerated by treatment of the materials with acids or acid salts.  According to the amount of viscose applied, the materials have a raised safe ironing point, a decreased tendency to ladder, split, or slip, or an affinity for cotton colours.  In an example, cellulose acetate threads are passed firstly through 75 per cent ethanol, then through a viscose containing 1,5 to 2 per cent of cellulose, and finally through a solution of sodium bisulphate.  In another example, a cellulose acetate fabric is treated firstly with 40 per cent acetic acid and then with a solution of viscose containing 1 to 1,5 per cent of cellulose.  The cellulose is regenerated by treatment of the fabric with benzene sulphonic acid. Specification 323,521, [Class 2 (ii)], is referred to.

Title: Improvements in or relating to apparatus for winding bobbins and the like with a band of material
Inventor: LASZLO AKOS
IPC: B65H54/28
Filed: 1963-04-19
Abstract: 1,064,062. Winding on to bobbins; tension devices; stop motions. JERSEY-KAPWOOD Ltd. July 9, 1964 [April 19, 1963], No. 15474/ 63. Headings DID and D1J. Flat strip-like material 66 is wound on to a bobbin 14 by feeding the strip through a tension device 41, 42 and then over a stationary guide 38 on to a bobbin 14 that performs a reciprocating motion to traverse the strip thereon. As shown, the resulting package on the bobbin 14 is driven by a drum 13 of sponge rubber that reciprocates with the bobbin 14, the reciprocating motion being created by a piston and cylinder arrangement 21, 22. Adjustable switches 25, 26 enable the stroke length to be predetermined according to the length of the bobbin to be wound. The drum 13 and a length counter 32 are driven by a common motor 2 having an electromagnetic brake 3. Stop motions. Failure of the supply of strip material is sensed by a finger 53 pressing on the material leaving the tensioning fingers 41, 42; and a fork 63 senses any snarls or tangles of the material leaving a supply box 65. Operation of the finger 53 due to failure of supply, or operation of the fork 63 due to a tangle, or operation of the counter 32 on reaching a predetermined count, causes the motor 2 to stop and the electromagnetic brake 3 to be applied. The spacing between the fingers 41 and 42 is adjustable by means of a knurled screw 48. The guide rods 36 prevent lateral movement of the tape and the fingers 62 remove twists from the band as it is drawn upwardly. To commence a winding the ribbon end is stuck to the bobbin by adhesive tape. Modification. Duplicate guide rods, tensioning unit and tangle fork may be provided to enable two bands to be wound simultaneously on to the bobbin. The unit may be modified to wind on to a flat card instead of the bobbin 14. Photoelectric means may be included to detect faults, said detection being used to stop the machine or actuate a counter.
