Abstract
This invention is directed to a machine for compressively longitudinally shrinking a continuously advancing woven textile web and simultaneously ironing one face thereof and includes an endless rubber belt carried on a pair of parallel rolls (one of which is driven) and an idler roll parallel thereto. An oscillatory arcuate segment is interposed between the rolls and displaces the belt toward the idler roll. Preferably, the segment, which may be heated, is oscillated through a small amplitude more rapidly in the machine direction than in the opposite direction.

Primary Examiner- Robert R. Mackey Allorneys- Leo Fomero and Robert J. Dockery ABSTRACT: This invention is directed to a machine for compressively longitudinally shrinking a continuously advancing woven (8111116 web and simultaneously ironing one face thereof and includes an endless rubber belt carried on a pair of parallel rolls (one of which is driven) and an idler roll parallel thereto. An oscillatory arcuate segment is interposed between the rolls and displaces the belt toward the idler roll. Preferably, the segment, which may be heated, is oscillated through a small amplitude more rapidly in the machine direction than in the opposite direction.
COMPRESSIVE SHRIMGNG MACHINE PATENTEU AUG 3:97: 3. 596, 332
COP PRESS IVE SHRINKING MACHINE FIG. 2
OSCILLATING MACHINE roIi SIIITINKING AND FINISHING WOVEN TEXTILE FABRICS INVENTION This invention relates generally to new and useful improvements in shrinking and finishing woven textile fabrics and particularly seeks to provide a novel machine for effecting the compressive shrinking and one-side ironing of a continuously advancing fabric web through the use of an oscillating cylinder segment positioned against the upper flight of a continuously driven endless rubber belt.
The compressive shrinking and surface finishing of woven textile fabrics has become highly developed both as to methods and apparatus for effecting same. U.S. Pat. Nos. 1,861,423, 1,861,424, 2,005,517, 2,021,975, 2,078,529, 2,146,694, 2,721,370 and 2,885,763 contain disclosures representative of such developments. One feature common to all of these prior disclosures is that the fabric web, whether being compressively shrunk or surface treated, is passed through at least one compressive shrinking unit at some stage during which the fabric is acted upon by a progressively distorted felt or rubber belt running in juxtaposition to a rotary heated drum.
It has now been discovered that certain types of fabrics may be compressively shrunk satisfactorily and rectilinearly ironed simultaneously on one side, to provide a smoother finish and better hand, by employing a heated oscillating element in place of the rotary heated drums heretofore used. Therefore, an object of this invention is to provide an oscillating machine for compressively shrinking and finishing woven textile fabrics.
Another object of this invention is to provide a machine of the character stated that includes a driven endless rubber belt having its upper fiight downwardly displaced by a smoothfaced generally semicylindrical oscillating heated segment.
Another object of this invention is to provide a machine of the character stated in which the amplitude of oscillation of the segment is relatively small and at a moderate frequency that is determined primarily by the physical characteristics of the fabric being operated upon.
Another object of this invention is to provide a machine of the character stated in which oscillation of the segment is effected by a quick-retum mechanism so that oscillation in the machine direction is relatively fast while that in the return direction is relatively slow.
A further object of this invention is to provide a machine of the character stated that is simple in design, rugged in construction and economical to manufacture.
DRAWING With these and other objects, the nature of which will be apparent, the invention will be more fully understood by reference to the drawing, the accompanying detailed description and the appended claims.
In the drawing:
FIG. 1 is a schematic side elevation of one form of fabric processing apparatus including a compressive shrinking machine constructed in accordance with this invention; and
FIG. 2 is an enlarged side elevation of the compressive shrinking machine portion thereof. 1
PREFERRED EMBODIMENT Referring to the drawing in detail the invention, as'illustrated, is embodied in fabric treating apparatus in which a continuously advancing fabric webA first may be subjected to a water spray or other pretreatment by a device, schematically indicated at 5, then passed through the compressive shrinking machine of this invention generally indicated at'6, and then through a dryer generally indicated at 7 after which it is generally plaited or zigzag folded into a delivery cart.
The compressive shrinking machine 6 includes an endless rubber belt 8 carried by a driven nip roll 9, an idler roll 10 and a lower idler roll 11. The portion of the belt 9 that is intermediate the rolls 9 and 10 is displaced downwardly in a uniform are by a generally semicylindrical segment 12 that extends across the full width of the belt 8 and may be heated by steam or other suitable means (not shown). The segment 12 is mounted on a rock shaft 13 and is provided with an upwardly directed vertical arm 14 having a pair of roller cam followers 15,15 rotatably mounted on its upper end. A set of mated driven cams l6 and 17, that are 180 out of phase with each other, respectively engage the roller cam followers 15 to impart an oscillating motion of small amplitude to the segment 12. Typically, the amplitude of oscillation would be on the order of 2, the frequency of oscillation would be on the order of 300-400 cycles per minute and the linear speed would be on the order of yards per minute, but could vary from as low as 15 y.p.m. to speeds greater than 125 y.p.m. The cams 16 and 17 are contoured in such a manner that the forward oscillation of the segment (machine direction) is relatively fast while the return oscillation is relatively slow so that the relative velocities between the fabric and the segment are equal in both directions.
In operation the belt 8 functions as in the prior known compressive shrinking machines to effect the compressive shrinking of the fabric as it is moved across the arcuate face of the segment 12, while the oscillation of the segment during passage of the fabric effectively irons the contacting face of the fabric to smooth same, add luster thereto and improve the hand of the fabric. The machine shrinkage obtained is generally on the order of 5-8 percent, but may be somewhat lesser or greater depending on the physical characteristics of the fabric being run and the nature of any pretreatment to whichthe fabric has been subjected.
It also should be noted that less heat is required in the segment 12 to produce a given amount of shrinkage than would be required for prior known types of compressive shrinkage machines.
I claim:
