Title: Process and apparatus for the drawing and crimping of synthetic filaments
Inventor: STANLEY ROBERT KENNETH
IPC: D02G1/00
Filed: 1968-03-07
Abstract: 1,209,816. Drawing and crimping synthetic filaments. TECHNISERVICE CORP. 7 March, 1968, No. 11167/68. Heading B5B. An apparatus for combining the drawing and crimping of a synthetic monofilament or a bundle of synthetic filaments (both hereinafter referred to as a strand) comprises a pair of feed rolls 12, 13, Fig. 1, feeding a strand 11 through heater 14 to snubbing member 15 which has a semi-cylindrical snubbing surface 16. The strand is pulled over this surface by a pair of draw rolls 17, 18 and thereby stretched (after which it is denoted as 11<SP>1</SP>). The feed and draw rolls are driven by drive means 19 through power transmission means 19a and 19b. The snubbing member may be hollow and may be cooled by circulating through it a fluid cooling medium cooled by a refrigerator 25 and circulated through the interior of the snubbing member by means of the conduits 21 and 23. Alternatively the members 21 and 23 may be electrical conductors leading an electric current from an e.m.f. source to a member 22 in the snubbing member 15, the member 22 being a thermoelectric device (e.g. a Peltier junction) adapted to cool the snubbing member 15 when a current is passed through it in the appropriate direction. Heater 14 is adapted to heat the entire strand uniformly as it is pulled towards the snubbing member. If it is desired to impart a very pronounced crimp to the strand an additional heater 24 is used to produce a temperature gradient across the individual filaments of the strand from the side of the filament heated (momentarily) by heater 24 to the side of the filament cooled by contact with the snubbing surface 16. Heater 24 extends for at least as much of the width of the snubbing surface 16 as is covered by the strand being drawn thereover. The tip of the heater is tapered to concentrate the heating effect at a narrow line across the snubbing surface transverse to the path of travel of the strand. The heater 24 is preferably slightly spaced from the strand unless modified for rolling contact with the strand. As shown in Fig. 2, the drawn strand 11<SP>1</SP> after leaving the draw rolls 17 and 18 may be drawn through a heater 27 by means of a pair of forwarding rolls 28, 29 driven by power transmission means 19c under only sufficient tension to prevent slack in the strand. This tension is released as the strand leaves the rolls 28, 29 and the relaxed strand then develops a pronounced crimp as shown at 11<SP>11</SP>.

Abstract: 1494525 Folding edges; laminates PROCTER & GAMBLE CO 18 March 1975 [18 March 1974] 11246/76 Headings B5K and B5N [Also in Divisions D1-D2 and A3] A reinforced absorbent web 13 for a diaper is formed by treating at least one surface of an uncompacted absorbent web 1 of hydrophilic fibres having a basis weight of 80 to 500 g/m<SP>2</SP> and a density of 0À03 to 0À05 g/cc. by applying a hydrophobia, film-forming material thereto to give a total treated depth not exceeding 50% of the total thickness of the uncompacted web, drying the film-forming material and compacting the web to an overall density of 0À07 to 0À15 gms/cc., the density of the treated surface(s) being lower than that of the untreated portions, thereby providing a graduation of capillary size favourable for the transmission of liquid from the treated to the untreated portions. Unspecified hydrophilic cellulosic fibres are air laid at 2 and the continuous web sprayed at 3 with a 10 to 55% aqueous dispersion of a styrene-butadiene or acrylic resin having a glass transition temperature of -15 C. to + 35 C. to give a 5 to 16 g/cm<SP>2</SP> uptake of solids. Selected areas may have different or zero amounts of resin applied. The moisture content is reduced to less than 5% and the resin cured by air at at least 270 F. supplied by dryer 5. The web is then calendered by rolls 9, 10, the resin preventing inter-fibre hydrogen bonding in the treated portion 13b whilst the untreated portion 13a is densified. Diapers, laminating, seaming.-The endless web 1 is cut into pads 13 by knife 11 and the pads separated. An impervious matt finish polyethylene backing 15 is sprayed with a soft pressure-sensitive polyvinyl acetate copolymer adhesive 17 and laminated to the spaced assembly of pads 13. A low density hydrophobic top sheet 16 comprising a needle bunched polyester fabric or a viscose rayon fabric printed with discrete areas of hydrophobic binder is pressed against the resin treated portion 13b of each pad. Beads 19 of hot melt adhesive are applied to each edge of sheet 16. Ploughs 21 turn over each edge of sheets 15, 16. Hardsurfaced rolls 22, 24 press each turned over edge together and press the adhesive coated sheet 15 to the top sheet 16 in the areas between the pads 13, roll 22 having recessed areas 23 to accomodate pads 13. The turning over of the edges prevents rucking by top sheet 16. Alternatively this can be achieved without turning over by sizing the edges of sheet 16. Pressure sensitive tape for securing the diaper is applied to each pad, the pads folded to the configuration of Fig. 6 and the pads separated by cutting the sheets 15, 16.

[Class 27.] The Specification refers to a game in which balls are projected towards an apertured target provided with a score recorder zeroized by mechanism which releases the balls for play. In the construction shown, balls are projected by a spring gun 4 up an inclined surface 5 into a target 6 having annular channels 6<a>-6<d>, each discharging into a pan 9 carried by a counterbalanced lever 8 bearing against a common bar 11, which carries a pawl 16 for advancing a ratchet wheel 17 and score indicating disc 23 each time a ball falls into a pan 9. The arms 8 are of unequal length so that the disc 23 is rotated an amount appropriate to the score assigned to the channel in the target into which a ball enters. Contacts may be associated with one of the arms 8 for completing the circuit of an electric bell when a bull's eye is scored. After discharge from the pans 9, the balls are directed to their out of play position upon a pivoted rail 15. To release the balls for play, a coin is inserted in a slot 40, and a bar 39 thrust in, so that a pin 43 drives forward a bar 32, a cam 46 thereon tilting the rail 15 so that the balls fall to a lower compartment from which they can be raised one at a time, and directed to the gun 4, by a lever 38 having a forked end 48. The bar 32 is also coupled by a bell-crank 33 and a link 31, to a pivoted member 30, which disengages pawl 16 and a back stop pawl 19 from wheel 17, so as to permit a weight 29 to zeroise the score indicator. Two modified forms of score indicator are described, one comprising aligned indicator drums, which may have carry-over mechanism between them, each having ratchet and pawl advancing mechanism and zeroizing mechanism as described above, and another in which such indicator drums are arranged on coaxial shafts, each carrying a ball-operated star wheel projecting into passages leading from the target apertures. Coin action, mechanical-connection.-The coin enters a slot in bar 39 and raises a pivoted detent normally locking the bar when it is thrust in.
