Title: Improvements in or relating to thread tensioning devices for textile machines
IPC: B65H59/24
Filed: 1953-08-07
Abstract: 746,858. Automatic thread tensioning devices. BRUGGER, A. Aug. 7, 1953 [Oct. 18, 1952], No. 21896/53. Classes 120 (2) and 142 (1). A self-adjusting thread tensioning device comprises a tensioning lever engaging and tensioning the thread, a spiral spring acting upon said lever against the action of the tensioned thread, further thread engaging tensioning means arranged behind said tensioning lever in the direction of travel of the thread, a pressure spring co-operating on the one hand with said further tensioning means and on the other hand with a second arm of said tensioned lever, said pressure spring and said spiral spring tending to pivot said lever in opposite directions with respect to each other. As shown, the device is mounted on a supporting rod 6 by a two-part clamping device 2, 3, the part 2 having a plate 1 attached thereto. The plate 1 carries a supporting axle 8 on which two discs 9 and 10 forming the tensioning means proper are mounted. The disc 9 is rigid against an abutment 11 and the disc 10 is movable on the axle 8. An arm 5 extends from the plate 1 and carries an axle 18 on which is journalled a two-armed lever 13, 15. The arm 13 bears through a comparatively weak spring 12 against the movable disc 10 and the arm 15 carries at its free end a loop 15a for guiding the thread A. The axle 18 also carries the casing 19 which houses a spiral spring 20, the outer end of which is secured to the casing and the inner end engages a reduced portion of the hub 14 of the rocking lever 13, 15. Between the casing 19 and the arm 5 is a spider shaped blade-spring 32 which serves to maintain a spring 20 in an angularly adjusted position. In operation increase in tension of the thread A rotates the rocking lever 13, 15 against the action of spring 20 and so relieves the pressure of the disc 10 on the disc 9 and any decrease in tension allows the spring 20 to rotate the lever 13, 15 and thus increase the pressure between discs 9 and 10. A lower guide support 24 and an upper similar support 25 are provided for guiding the thread A through the tensioning discs 9 and 10.

The preservative may be sodium sulphite. A fixed (i.e. the amount of alkali available is unbuffered) alkali may be present as an activator for the 3-pyrazolidone e.g. a combination in solution of paraformaldehyde and sodium sulphite. Alternatively a buffered alkali may be used e.g. buffered sodium carbonate. The superadditive developing agent may be hydroquinone. The pH of the solution may be 8-12. The 3-pyrazolidone may be 1-phenyl-3 pyrazolidone. This developer may be used to produce continuous printing tones on an imagewise exposed high contrast, thin emulsion film by developing with a solution as defined above for 2-128 minutes at 18‹-27‹C. and fixing. The invention also comprises a concentrated aqueous alkaline solution of the developer defined above.

Abstract: 813,705. Stencilling-apparatus. BALMER, W., and HERON, J. U. July 16, 1956, No. 21939/56. Class 100(2) A screen printing machine of the reciprocating screen and rotatable cylinder type, comprises a transverse member 23 which reciprocates with the screen, grippers 23a carried by the member 23 to grip the leading edge of a sheet to be printed by which it is drawn between the screen and cylinder 17, a delivery conveyer 22 to receive the printed sheet, guides 24 for the ends of the member 23, the guides being inclined relative to the plate in which the screen reciprocates and further guides 21a for the ends of the member 23, the guides 21a being slightly, inclined relative to the normal of the plane in which the screen reciprocates. The guides 21a and 24 combine to guide the member 23 so that the resultant travel imparted to the grippers 23a during the printing stroke is progressively away from the screen but the linear travel is never greater than that of the screen and the sheet gripped by the grippers is peeled progressively and continuously throughout the printing stroke without danger of increasing the tension on the sheet. The screen frame 18, is mounted for reciprocation by means of a cam 19b fast on a driven shaft 19a and which causes reciprocation of a member 19c connected to a rod 19d. The rod 19d is pivoted at its lower end and connected to lugs 19e on the frame 18 at its upper end. The lugs 19e are provided with the guide slots 21a in which are fitted the ends of the transverse rod 23 carrying the grippers 23a which can move up and down in the slots. When the frame is in the dotted position shown, the grippers 23a grip a sheet and, as the frame moves forwardly, pull it between the impression roller 17 and the screen in the frame 18 upon which a squeegee 21, fed from an ink reservoir 20, is operative. During the rearward movement of the frame 18 the roller 17 and squeegee 21 are rendered inoperative by means of rods 20b operated by cam 20a. The printed sheet is delivered on to the downwardly inclined conveyer 22 by the grippers 23a which are constrained to move downwardly by the guides 24 so as to conform to the level of the conveyer 22.

Seam flanges 41, 56 and 44 are formed on the upper and lower sheets and stations 2 and 3 and the break lines for the edges of the duct are marked at station 3, Fig. 5. The sheets are guided over an inner former 10 at station 4 and dies 66, 71, 69 at station 5, Fig. 7, bend the sheets round the former 10 and urge the sealing flanges into position. At station 7, Fig. 9, rotary dies 78, 81 press the sheets on to former 10 and the sealing flanges into engagement, to be squeezed together by camming members 83, 84, Fig. 15, at station 8. Rotary dies at station 9 are shaped to secure the seam by buttons 92, Fig. 16, at 3 inch intervals. Rotary dies at stations 10 and 11 flatten the seam if required. In a modification, the seams are made at the upper corners of the tube, the upper sheet being narrower than the lower sheet. A single motor drives the rotary dies through chains and gear trains and the whole is mounted on a frame supported on rollers.
