Definitions

  • the superficial contraction of the web is produced by pressure exerted in, directions parallel to its surfaces; since by reasonof the confinement of the web by the pressure maintained on its entire surface it can not wrinkle as a web or sheet in response to the ⁇ contractile force exerted on it, the response to that force is by the component yarn systems within the Web (one or both) of which the web is composed, which assume a more pronounced undulation or crinkle, contracting the web without wrinkling its surface. This may, for the sake of brevity, be termed shrinkage by compression.
  • Apparatus by which shrinkage by compression is effected is exemplified by one endless band of such thickness and structure that on being flexed during its movement successively in one direction and then in the reverse, that side of the band which is first convex and then concave lengthens and then shortens, so that a moist Web of cloth laid upon and attached by pressure to, this convex sector partakes of the contraction of the band surface when the latter passes into the concave sector, when also the confining pressure continues to be exerted on the web.
  • this convex sector partakes of the contraction of the band surface when the latter passes into the concave sector, when also the confining pressure continues to be exerted on the web.
  • the web responds to the contractile force by the crinkling of the warp yarns.
  • the present invention aims to provide novel and improved apparatus for cloth shrinkage by compression; particularly to provide apparatus utilizing many parts of commercial cloth drying or finishing machines, significantly.rearranged and modified with alteration of function so as to produce this type of shrinkage.
  • a further object of the invention is to provide an improved organization of instrumentalities capable of confining the cloth web against the convex surface of a moving band, and without any substantial release of this confinement, so altering the curvature of the band as to produce shrinkage by compression.
  • Fig. 1 is a diagrammatic side elevation of a cloth-shrinking machine embodying features of the present invention

  • Fig. 4 is a vertical section on the line 44 of Fig. 2;
  • Fig. 5 is a view similar to Fig. 4, but showing certain ironing instrumentalities of the machine in an inactive position.
  • the compressive shrinking machine of the present invention is suited to form part of the general organization of cooperative cloth-finishing devices described in my copending application serially numbered 516,972, filed Feb. 19, 1931.
  • Fig. 1 shows how, in obtaining accurate two-dimensional preshrinkage, as explained in that application, a textile web W may be conducted from a tentering machine T, through rolls R, R, past water moistening devices M, M, and smoothing and spreading bars or rolls G, G G and Gr to a machine of the present invention operating on the principle of compressive shrinkage.
  • This machine of the present invention for effecting shrinkage by compression includes an endless flexible band F, for example of felt about A t-h of an inch thick, which is carried over the convex surface of a member R defining a part of the path of travel of the band.
  • This member R preferably is a rotatable roll.
  • the band F passes therefrom on to the surface of a second member D which moves past the convex surface of this first member R
  • this second member D is a large rotatably driven cloth-drying drum, provided with means for internal heating (not shown) the band F may then pass around the major portion of the drum to and over a series of rolls R R and from thence return to member R Any one of the several rolls R may be adjusted to impart a sufficient tension to the band F to enable the band to be driven by the drum D.
  • suitable springs are preferably provided for urging the roll R against the band at this point.
  • the textile web W to be subjected to warpwise compressive shrinking is receive in a moist plastic state the baud F passing over the member R From thence the web band F as the latter is transferred to the drum D. After passing around the drum D with the band F, the web W diverges from the band as diagrammatically indicated in Fig. 1. ide webs of a yard and more in width can be successfully handled.
  • Means is provided for causing the roll R and drum D to nip the band F and its associated textile web at the point where the band and web are transferred from the roll to the drum.
  • the roll R is mounted at opposite ends in frames A which are pivotally mounted at A to a stationary upright G, the pivot point A being in the present instance above the axis of roll R and offset therefrom toward the drum D, so that the pull of the band F will draw the roll R toward the drum D.
  • a journal J at each of its ends is preferably embraced by opposed cupped bearing blocks K and K which are vertically adjustable by means of upper and lower adjusting screws L and L turning in bosses X and X on the frame A.
  • means is provided for adjusting the degree of compressive nipping of the band and web between the roll R and drum D; a preferred form of such means may include a pin V carried by the pivoted roll-carrying frame A and adj ustably pressed by a spring V against the upright G, thus adj ustably limiting and cushioning the pivotal movement of the frame A and roll R toward the drum D.
  • a sleeve T pivotally secured at T to the frame A may take by the convex surface of W accompanies the.
  • Such means preferably takes the form of a plurality of ironing blocks I disposed closely side by side across the width of the web W (Fig. 3) and each conforming (Fig. 4) to the convex surface of the web W passing the member R Preferablv these ironing blocks extend as near as possible to the the curvature of the web immediately before the web is nipped as described above.
  • the web is transferred from pressure-confinement against the band F to similar confinement against the moving surface of the drumD with no substantial release from pressure against the band.
  • the moisture contained in the web for example 10% by weight. of water) as a consequence of previous moistening by the water spraying devices M, enables the web to be firmly affixed or attached to the band F prior to 'fleXure of the band in passing onto the drum D.
  • the ironing blocks I preferably contain electric. heating elements Y, which may be of conventional form; the ironing blocks thus heated aflix the plastic web W to the band F both by heat and pressure.
  • the heating of the ironing blocks I is of particular utility nip point N. conforming to pendently on the cloth, thus ensuring that all parts of the width of cloth are firmly confined against and attached to the band F, regardless of slight flexure of the roll It.
  • Each ironing block I while having freedom of motion normal to the web W, may be prevented from being carried by the webtoo tightly against the drum D or from being wedged unduly between the drum D and roll R, by the provision of an adjustable abutment in the form of a screw bolt 0 atlixed in the lower flange of a channel iron 0 and taking against the upper surface of a lip I on the ironing block.
  • Each ironing block I or e uivalent web-confining member may if dBSiIEK be yieldingly urged against the web W, not only by gravity but also by spring action; as -shown in Fig. 4;, a spring V* attached to the channel iron 0, and to the lip I of the ironing block, may urge the block against the web, about the bolt 0 as a fulcrum.
  • the machine is adapted in its operation to produce preshrinkage by compression, as follows: v
  • the web W is in a moist condition when it enters between the band F and blocks I, so that its component yarns are soft and their fibre structure capable of internal movement.
  • the web is transferred from pressure-confinement against the band F by the blocks I to similar confinement between the band and the'surface of the drum D, with no appreciable, or more than an instants release from pressure against the band, so that the reversal of curvature of the band, and the consequent shortening of its web-carrying surface. is accompanied by a corresponding shortening of the moist web, of which the yarn components (warp in this case) produces take up or shrinkage by undulation or crinkle.
  • the shrinkage produced in the web is then set by the heating and drying on the hot drum D, and the web drawn from the band to be rolled or web folded. If a given length of the convex surface of the band F. upon the roll R be represented by L, and this, upon passing to the drum Dcontracts to a length L the linear contraction is expressible by LL and the percentage of shrinkage by shrinkage producible in a web by the means above described.
  • the extent of; contraction (Ia-L of the band F in passing from the roll R to the drum D is an inverse function of the radius of roll R andis a direct'function of the thickness of the band F; and the extent of shrinkage in a web W ma be regulated by a suitable proportioning 0 these values.
  • Suitable means for accomplishing these functions preferably includes a pair of brackets E at opposite ends of, and affixed to, the channel O, each of these brackets E being pivotally mounted at E to a curved plate A? by the pivoted roll-carrying frame A.
  • the two brackets E thus movably support the channel 0, forming together therewith a yoke which can be swung from the position of Fig. 4 to the position of Fig. 5; an extension E of each bracket E in this position strikes a stop Eand checks further movement of the brackets E and channel 0.
  • the individual ironing blocks I may be caused to move as a unit with this yoke by suitable connections thereto, thus being removed from contact with the cloth web, as shown in Fig. 5.
  • suitable connections provide freedom of movement of the individual blocks when the yoke and blocks are in normal operative position, as in .Fig. 4.
  • Figs. 3 "and 4 across the group of blocks I is afii'xed at intervals to the'channel I by brackets P fast thereto.
  • Each ironing block I then carries one or more hooks I disposed to engage the rod Pof the above described yoke construction when the latter is swung to the right, but free from the rod P when the blocks I are in their normal operating position.
  • a rod P extending which is supported order to hold the yoke, including brackets E, channel 0 and rod P, free from the blocks I during operation of swinging hooks P may be provided on each plate A, adapted to latch over the rod P.
  • each ironing block I Preferably electrical connections to the heating elements Y of each ironing block I are so arranged as to permit ready detachment of any of the individual blocks.
  • electrical wires Q connected to the several heating elements Y of a block through holes in the top of the block terminate in a detachable plug Q ⁇ .
  • a smaller channel member 0' within the flanges of channel 0 carries on the outer face of its web suitable electrical outlets Q to which the plugs Q may be detachably connected.
  • the necessary wires leading from asource of energy to the outlets Q are preferably enclosed in the space between the channels O and O.
