Abstract:
An apparatus for the continuous wet treatment of woven fabrics and knitted fabrics comprising a casing (1) provided with an entry slot (35) and an exit slot (36) for the fabric (34) under treatment, a curved widening cylinder (16), a series of rollers (8-14) covered with a rubber layer with their axes parallel and transverse to the fabric feed path, the rollers being arranged in zig-zag formation in a vertical plane one in contact with the next. The series of rollers comprises in succession idle roller, presser rollers and a motorized roller (8). The apparatus also comprises a squeezing roller (15) positioned in proximity to said exit slot in contact with the motorized roller. There are also provided devices for adjusting the contact pressure between the presser rollers and their adjacent rollers and between said squeezing roller and its adjacent roller, and pairs of scraper seals positioned against the side ends of each mutually contacting roller pair of said series. Finally, there are provided two treatment liquid feed pipes (18, 19) in the top of the casing in positions corresponding with two different contact regions between the rollers, and a treatment liquid discharge pipe (33).
Abstract:
A pressure saturator (10) for impregnating a substrate (12) with a saturant is disclosed, having a block member (26) with an arcuate, sloping upper surface that is graduated from a relatively deep portion (60) to a relatively shallow portion (64). Rollers (18, 20) are disposed on each side of the block member for conveying the substrate into and out of the saturator, and a mandrel (16) is disposed between the rollers for guiding the substrate through the saturator. The lower portion of the mandrel is spaced from the block member and extends into the recess formed by the arcuate surface to define a chamber (28) therebetween. The chamber has an inlet (30) and an outlet (64) for admitting the substrate and the saturant, and converges in depth from the inlet region to the outlet region to pressurize the solution and force the saturant into the interstices of the substrate. The invention has application to production of construction materials such as counter tops by impregnating substrates such as paper with saturants such as thermosetting resins.
Abstract:
In the technical field of machines for treating fabrics or the like while being processed, there is provided a system for continuously scouring woven or knitted fabrics, in their flat or tubular condition, which can be used in the preparation, mercerization, scouring after dyeing and after printing, as well as during the final finishing stage. The technical problem faced is that of providing a system of a truly universal type and with a specially efficient scouring action, such that no tension is exerted on the fabric being scoured, while allowing the fabric to change its shape spontaneously. The solution to the problem consists of providing a system which comprises a plurality of parallel and closely adjacent rollers (3, 4) such that they cause the fabric (2) or the like to follow a path of substantially continuous contact with the rollers (3, 4), which are all driven in a non-rigid manner, and comprises means (5, 8,4, 3) adapted for subjecting the fabric simultaneously to three different types of scouring action.
Abstract:
A permeation system for permeating a wetting agent into fabric includes a fabric supply part; a permeation part provided with a permeation device and a height adjustment device; a drying part; and a collecting part for winding the fabric, which has passed through the drying part, around a collecting roll, thereby obtaining functional fabric of uniform quality and increasing productivity of the fabric into which the wetting agent is permeated. A method for manufacturing fabric includes adjusting the height of the permeation paddle contacting the fabric; supplying the fabric; supplying a wetting agent to be permeated into the fabric; rotating the permeation roller and the permeation paddle to permeate the wetting agent into the fabric; drying the fabric into which the wetting agent is permeated; and collecting the fabric.
Abstract:
A washer that washes a continuous piece of tubular knitted fabric material. The washer includes a frame, a set of rollers, an air nozzle rack, and a controller. The frame rests on a support surface. The set of rollers are rotatably attached within the frame and guide the material through a washing liquid to wash the material. The air nozzle rack is replaceably attached to within the frame and blows air onto the material to cause ballooning of the material to maximize exposure of a total surface area of the material to the washing liquid. The controller is operatively connected to the set of rollers and minimizes and keeps constant the tension of the material as the material passes through the washing liquid under an influence of the air nozzle rack to thereby provide a more effective wash of the material.
Abstract:
An apparatus for applying treating liquor to a traveling textile web having a vat containing treating liquor and a plurality of web guiding rolls submerged in the treating liquor and arranged in a substantially vertical sequence with adjacent rolls being in contact to form nips therebetween. The upper rolls are supported in the vat for resting under their own weight on the lower roll to apply pressure at the nips on the textile web. A drive motor drives at least one of the rolls with the other rolls being driven by surface contact with the drive roll for positive feed of the traveling web at a uniform surface speed through the treating liquor. Guide rolls guide the textile web to the vat at substantially the same surface speed as that of the plurality of rolls. A pair of driven squeeze rolls above the treating liquor form a nip through which the textile web is guided as it travels from the treating liquor, with squeeze rolls being driven at substantially the same surface speed as the guide rolls.
