Apparatus for applying a liquid to a cloth or the like including a stamp roll having a peripheral surface provided with a pattern of pits. A rubbing block, having at least one material supply passage extending vertically therethrough, is disposed above the stamp roll in such a way that a lower rubbing surface of the block is in sliding contact with the peripheral surface of the roll. A supply container is connected to the material supply passage of the rubbing block for supplying the liquid through the block to the peripheral surface of the stamp roll. A pressure roll is disposed below the stamp roll in abutting relation thereto to carry the cloth into intimate contact with the peripheral surface of the stamp roll. The rubbing surface of the block is formed in the downstream side of the material supply passage with a plurality of parallel recesses extending orthogonally to the rotating direction of the roll where a portion of the downstream side rubbing surface is disposed between the material supply passage and the plurality of parallel recesses.

Apparatus for treating yarn ends while plaited in unstressed condition on a conveyor belt. In different portions of a machine the treatment consists in fixing dye-stuffs printed upon the yarns and drying the yarns after fixing and subsequent washing. A pair of rolls form a nip through which the conveyor belt and the plaits thereon pass upon leaving each of the treatment means. Yarn pulling means pull the yarns from the nip and off the belt, applying tension against the reaction of the nip without applying stress to the plaits advancing toward it.
摘要:
A method for coating textile bases with a specified pattern of synthetic powder wherein the synthetic powder is applied to a water-cooled engraved roller and transferred to a textile base material while being under heat treatment for a substantial portion of the travel of the textile base along the application roller. Such heat treatment is provided by heat emitters external to the application roller thereby providing heating of the textile base and the powder through it.

A retainer maintains a body of standing washing liquid against the outside surface of a mat, such as a pulp mat. The mat moves on a vacuum screen which draws washing liquid from the body of liquid through the mat to clean it. The retainer pivots to adjust different mat heights and allows clumps of material on the mat to pass underneath the retainer. Clumps on the mat are also smoothed into the mat as the clumps pass underneath the retainer.

An apparatus for applying a treating solution to a cloth during the continuous treatment thereof, comprising: a cloth guide drum for transporting and guiding a cloth to be treated; a movable treating solution tank provided in close proximity to the circumference of the lower half of the cloth guide drum thus forming a cloth passage of a narrow width therebetween; a cylinder for raising and lowering of the movable treating solution tank; a treating solution supply pipe for supplying a treating solution continuously to the cloth passage; and wash-water jet nozzles for propelling wash water to the inner surface of the movable treating solution tank, the surface of the cloth guide drum, etc.; and its modifications. The operation of exchanging the treating solutions during the continuous treatment of a cloth can be done in a rapid and effective manner with a minimum loss of the treating solution.

A process is provided for coating of substrate webs with polyethylene wherein the edge thickening and other processing difficulties caused by the necking-in phenomenon are minimized. The process comprises extruding a polyethylene having a melt index between 30 dg/min and 100 dg/min through a slot in a slotted die in the form of a sheet onto the moving substrate web to form the coated web, and passing the coated web through a nip roll assembly comprising a chill roll and a nip roll, the slotted die having at the extremities of the slot therein edge guides which are maintained at a temperature above the melting temperature of the polyethylene and are contoured to guide the adhered edges of the extruded sheet into the throat of the nip roll assembly.
摘要:
One or more liquids may be applied to a running textile web in flat tubular or open width form by three different cooperative and integrated systems. A drying chamber is associated with the apparatus for recovering solvent which may be included in certain liquid chemicals. The chemical applicating apparatus includes spray nozzles spaced transversely adjacent the path of travel of the web for spraying chemicals on the moving web. Guiding means are provided for selectively positioning the web with respect to the nozzles for optimum spraying position. A padding tank is also provided for passing the web directly through a bath of the chemical and a metering system including an applicator roll and an adjustable blade in different configurations is provided for applying precisely controlled amounts of chemicals to the web.
