摘要:
A dyeing machine with symmetrical double spiral fabric tanks includes a barrel body with a fabric inlet, two spiral fabric tanks arranged side by side with each other in the barrel body and installed on both sides of the fabric inlet respectively, and each spiral fabric tank having a fabric guiding tube, a spiral fabric sliding plate and a receiving tank. The two fabric guiding tubes are disposed proximate to adjacent sides and facing to the front side and arranged symmetrically with respect to the left and right sides. The two spiral fabric sliding plates are coupled to the rear end of the two fabric guiding tubes and configured to be spirally from top to bottom, so that cloths can be dipped and dyed in the two spiral fabric tanks.

A circulation protection device is provided for a conveyor-driven fabric dyeing machine that includes a machine body having a front end in which a fabric circulation detection idler and a fabric movement sensor are mounted and a rear end in which a rear fabric guide and a fabric management device are mounted. Control is conducted with a computer program so that when the fabric circulation detection idler detects the fabric is not in movement, the conveyor is shut down; and when the fabric movement sensor detects the fabric is moving excessively fast or slow or gets jamming and stopped, the conveyor is controlled to automatically adjust the speed thereof or stops operation. When the fabric falls from a dyeing tube down to a conveyor, the rear fabric guide adjusts an entry angle of the fabric and the fabric management device allows the fabric to be orderly deposited on the conveyor.

A rotary washer/extractor for use with textiles and other materials includes a dynamically controlled suspension system for supporting the washer/extractor from a stationary frame to minimize forces exerted onto the frame and transmitted to the floor or other structure supporting the washer/extractor. The suspension system includes a plurality of supports extending between the frame and the washer/extractor at spaced apart locations in relation to the spin axis. At least one of the supports is a variable length member which may be continually adjusted to vary the distance between the frame and the washer/extractor and thereby minimize the forces caused by eccentric masses of textiles and washing fluids contained in the washer/extractor. A force sensor is provided for measuring the force acting between the washer/extractor and the frame. A processor is provided for receiving the measured force and generating an output response for varying the length of the support to minimize the value of the force and its vibratory effect on the frame. The suspension system is particularly useful for rotary washer/extractors having a drum rotating about horizontal as well as vertical axes and is especially adapted for reducing and minimizing vibratory forces.
摘要:
The present invention relates to the treatments, particularly in a gaseous medium, of textile articles accumulated in folds and moving under the effect of their own weight along an inclined surface. According to the process of the invention, the displacement of the article is accompanied by a mobile surface in contact with the upper part of the folds formed by the article; this mobile surface is driven so that it moves at a speed approximately equal to that of the article when said article slides normally along the inclined surface. The mobile surface consits of an endless belt whose outer surface, in contact with the upper face of the folds formed by the article, is at a constant distance from the inclined wall.

A tensioning unit (10) with automatic control of the tension (T) of yarn-formed fabrics (F), having a first electric card (50) mounted in an electromechanical cubicle (60) and used to set the drawing parameters or store and load applicational drawing programs, and a second electronic card (50A), identical to the first and mounted on the tensioning unit (10), and which utilizes a processing program to control an inverter (28), that is connected to a drawing motor (25), in response to a feedback signal originating from a linear position transducer (P) rigid with a spring (30) for tensioning the yarn; a third electronic card (40A) is provided to establish communication between the first electronic card (50) and the second (50A) via a serial line (54) using an infrared optical coupling system. The speed of the motor (25) is controlled on the basis of information received to the position of the spring (30), in such a manner as to maintain the yarn tension (T) constant.
摘要:
A removable treatment vat is connectable via a quick-release coupler to a fixed installation including a control unit together with a fluid monitor and a fluid driver for driving treatment fluid(s), said fluid driver being suitable for causing the fluid(s) to circulate under given conditions of flow rate, pressure, and temperature, from a fluid inlet to the coupler to the vat. The fluid driver includes a fluid circuit and a circulation pump; the control unit includes an electronic control circuit suitable for running the treatment process as a function of data coming from the above-mentioned fluid monitor and data specific to the vat, and possibly also data specific to the treatment proper.
摘要:
The present disclosure relates to a process for the treatment of thick, voluminous textile materials such as carpets, plushes, needled felts, and the like, made, for example, of wool, polyamides and polyacrylonitrile fibers. More particularly, the present disclosure is directed to a process for dyeing or printing large widths of thick, voluminous textile materials which comprises applying the dyestuffs and auxiliary agents to the textile material, heat-treating said textile material in a heating-up zone, steam-treating the textile material to set the dyestuffs in a dwell zone, washing the textile material and drying the textile material with hot air.
摘要:
A moving warp sheet is optically monitored by two lights beams in the plane of the sheet, with light-responsive transducers located to receive the beams. The beams cross the sheet along imaginary lines which intersect outside the sheet. The defective threadline is identified by the time interval between actuations of the transducers by a flaw.

THIS INVENTION IS DIRECTED TO APPARATUS FOR THE COMPRESSIVE SHRINKING OF TEXTILE FABRICS AND HAVING A GAUGE FOR MEASURING THE DISTANCE BETWEEN EQUALLY SPACED LONGITUDINALLY ALIGNED PHOTO-SENSIBLE INDEX MARKS ON A CONTINOUSLY ADVANCING WEB OF MATERIAL AND INCLUDES AT TRIGGER PHOTOCELL FOR DETECTING THE PASSAGE OF A FIRST INDEX MARK AND FOR ACTIVATING A PLURALITY OF COUNTING PHOTOCELLS TO MEASURE THE CONTINUING PASSAGE OF THE FIRST INDEX MARK UNTIL A SECOND INDEX MARK REACHES THE TRIGGER PHOTOCELL AND CAUSES IT TO CAUSE DISCONTINUANCE OF THE PASSAGE MEASUREMENT OF THE FIRST INDEX MARK. VISUAL MEANS ARE PROVIDED TO INDICATE THE LENGTH OF PASSAGE OF THE FIRST INDEX MARK ALONG THE COUNTING PHOTOCELLS UNTIL PASSAGE MEASUREMENT IS DISCONTINUED.
