Abstract: 1,079,470. Cutting webs. EMIL HOOGLAND G.m.b.H. ZUSCHNEIDEMASCHINENFABRIK. Aug. 24, 1965, No. 36293/65. Heading B4B. [Also in Division D1] A worktable on which webs 19 of fabric are laid in stacks 63, is provided with a movable cutting rail 43 which is constructed so as to be movable over end rails 61 used for clamping the stacks 63. A bale 17 of fabric, which is to be laid in the form of stacks 63, is disposed in a trough 21 and the fabric web 19 withdrawn therefrom is conveyed by a roller 23 towards a guide carriage F. The roller 23 is fitted with a braking motor and comprises a change-over switch 25 actuatable by a bar 27 so as to rotate the roller in either direction and to stop this roller. The bar 27 extends the whole length of the work-table. The leading edge of the web 19 is fed beneath a clamping bar 45 in the carriage F, which bar has been lifted by a handle 65, Fig. 3. (not shown), from the cutting rail 43 mounted on guide rails 41, Fig. 2 (not shown), arranged between rollers 39 extending between uprights 35. The handle 65 is released so that the bar 45 clamps the web 19 against the rail 43. Additional pressure may be provided by a spring and the bar 45 may have a rough surface. The operator then moves the carriage F, which is mounted to run on rollers 31 along guide rails 29 and may be provided with drive means, if necessary, to carry forward the web 19. The force to withdraw the web 19 is provided solely by the roller 23 by actuating the bar 27 at any position along the work-table. The carriage F is moved to the right-hand end, Fig. 1, of the stack 63 next to be covered with a layer of fabric and the handle 65 is again depressed. The operator grips the leading end of the web 19 and pushes that end beneath a corresponding end rail 61 carried by guide rails 59 guided by rollers 57 on vertically displaceable slides 55. The rail 61 holds the web 19 and the carriage F is returned to the left of Fig. 1, up to a second rail 61 until the knife slot 73, Fig. 3 (not shown), in the rail 43 is situated exactly over the left-hand end of the stack 63. During the return movement, the rail 43 slides beneath the fabric and the bar 45 is lifted by the handle 65. Cutting means 49, supplied with current from a cable 50, Fig. 2 (not shown), and normally situated outside the work-table width, is set into operation and guides a knife 51 in the slot 73 transversely of the table to sever the fabric. The end of the web is then pressed under the lefthand rail 61. Springs (not shown) may be provided to increase the bearing pressure of the rails 61. A smoothing member 75, Fig. 3 (not shown), on the rail 43 is normally held upwards by a spring (not shown) but during return movement of the carriage F is guided against the underside of the web to remove any folds or creases therein. The operation is repeated either on the same or a different stack 63, as desired. In a modification (not shown), drive means is provided on the rails 41 to facilitate the lifting thereof and locking devices may also be provided thereon to hold the rail 43 at a certain height. In a further modification (also not shown), the web may be laid as loops or folded double webs.
