Abstract:
A method and device for loading an offset master on to the plate cylinder of a rotary duplicating machine. Liquid adhesive is applied to the tail of the master prior to loading thereof, on the side which after loading contacts the master cylinder of the duplicating machine, so that the tail of the master is prevented from flapping and thereby becoming damaged. The invention is suitable for use with any form of rotary duplicating machine having an automatic clamp for engaging the leading end of a master being loaded.
Abstract:
Apparatus for the wet treatment of cloth in rope form wherein the treated cloth is drawn along by the treating liquor inside the treatment vessel which has substantially the shape of a right-angled triangle with unequal legs and rounded apexes and in which the liquid is pumped into the vessel through jet means housed in the vertical leg of said rightangled triangle, which leg has as an extension a cylindrical dome through which the cloth is introduced into the vessel.
Abstract:
An apparatus for wet treatment of warp-rope, or board-shaped textile goods, which comprises a U-shaped tube having at least two leg members, to constitute a treatment container. A drive set is provided which connects the leg members, and is adapted to circulate therein the textile goods. A liquid pump feeds liquid to the drive set and has a suction side and a pressure side. A connection conduit is disposed between the suction side and the pressure side of the pump, and a control member is provided in the connection conduit and serves the control of the quantity of the liquid to be fed.
Abstract:
A continuously connected textile fabric having seams at predeterined intervals is fed along its length to a succesive processing apparatus. The apparatus includes a plurality of squeezing rollers and a textile feeding path comprising a plurality of processing liquid tanks arrayed in turn, and seam detecting limit switches are provided at the places of the squeezing rollers, with the distance of the path between adjacent limit switches being chosen to be almost the same as the interval of said seams. In a state where the seams are positioned at the squeezing rollers, and thus at the limit switches, all the squeezing rollers are driven in a forward direction at once and after a predetermined relatively large forward travelling amount, they are driven in a backward direction by a predetermined relatively small backward travelling amount, the difference between the forward and backward travelling amounts being chosen to be approximately equivalent to a distance of the interval of said seams divided by an integer. During the final backward driving operation in one full cycle of the forward and backward reciprocating operations for the number of times of said integer, said limit switches are enabled and according to the order of arrival the seams drive the limit switches to bring the squeezing rollers to a stop. When all the squeezing rollers are brought to a stop, the limit switches are disabled to repeat again said operation cycle. Thus, during the reciprocating operation for the number of times of said integer, the textile fabric is fed in the forward direction by the interval of said seams while being processed, and the slip produced therebetween is compensated by the stop of every squeezing roller responding to each of the limit switches.
Abstract:
Means is provided for circulating textile material in endless strand form through a wet processing bath under the influence of a venturi-induced jet of a cycled portion of the treating bath. The jet arrangement includes a driven roll member provided for lifting the strand material from the bath, a venturi structure disposed horizontally beyond the roll member for subjecting the strand material to the jet influence, and a perforate baffle member designed to direct the strand material for orderly circulation beyond the jet influence.
Abstract:
DEVICE FOR THE WET TREATMENT OF TEXTILE MATERIALS, SUCH AS FABRICS IN ROPE FORM, COMPRISING TWO VENTURI INJECTORS OF THE CENTRAL SUCTION TYPE, THEIR RELATIVE POSITION BEING SO THAT THEIR OUTLETS ARE POSITIONED OPPOSED TO EACH OTHER. THE TEXTILE MATERIAL TRAVELS IN A CONTINUOUS FROM THROUGH THE CENTRAL SUCTION CONDUITS OF THE TWO INJECTORS INTO THE OUTER CONDUITS OF THE SAME WHERE THE TREATMENT FLUID IS INJECTED THROUGH REGULATING DEVICES WHICH PERMIT VARIATION OF THE FLUID FLOW QUANTITY SUPPLIED TO EACH INJECTOR BETWEEN 0% AND 100% OF THE TOTAL FLUID FLOW, AND, IN THAT WAY, THE SUCTIONAL POWER OF EACH INJECTOR. THIS DETERMINES THE FORWARD FEEDING OF THE FABRIC IN THE DIRECTION WHICH CORRESPONDS TO THE INJECTOR WITH THE GREATER SUCTIONAL POWER, AND THE OPPOSITE INJECTOR WITH THE SMALLER DRAWING POWER PRODUCES A SLOWING DOWN AND COMPACTATION EFFECT ON THE FABRIC.
Abstract:
A TEXTILE DYEING MACHINE OF THE TYPE IN WHICH AN ENDLESS STRING OR ROPE OF THE TEXTILE MATERIAL TO BE DYED IS CIRCULATED IN A CLOSED PATH INCLUDING A JET NOZZLE FED WITH DYE BATH UNDER PRESSURE AND SO SHAPED, THAT THE DYE BATH JET LEAVING THE SAME PULLS ALONG THE TEXTILE ROPE, SEPARATE MEANS BEING PROVIDED TO BRAKE THE TEXTILE ROPE BEFORE ITS ENTRANCE INTO THE ROPE DRIVING JET NOZZLE, CHARACTERIZED IN THAT THE MEANS FOR BRAKING THE TEXTILE ROPE CONSISTS OF A JET NOZZLE FED WITH DYE BATH UNDER PRESSURE AND DIRECTED OPPOSITELY TO THE DRIVING JET NOZZLE.
