This invention relates toapparatus for the orderly stacking or piling of textile rope in a container.

.In the textile arts, it is-generally desired to treat textile goods, for example, cloth, fiber bundles, piece goods and the like, with solutions such as dyeing, bleaching, scouring or similar solutionsto properly prepare the textile goods for merchandising. Frequently, with solutions are placed in containers for storage to permit the solutions to remain in contact with the goods over extended periods of time, or forpurposes of steaming, or otherwise heating goods previously subiectedto treating solutlons; for example, in the manner disclosed in U. S. Patent to Campbell et al. No. 2,267,718. Textile goods, in the process of treatment, also are frequently passed in a continuous manner through several pieces of equipment, and temporary storage means, referred to in the arts as slack boxes" or scrays, are provided between such' pieces'of equipment.

3 Claims. (01. 28-1) 1 goods treated Such textile goods are commonly formed into ropes or extended bundles which are fed into a storage container, or the like, by means of apparatus comprising a traversing mechanismin combination with a piling or plaiting mechanism; the traversing mechanism functioning to traverse the goods in rope form anism functioning to move the goods back and forth from front to back of the container. Such back and forth from side to side of the container, and the plaiting mechapparatus usually contains a plurality ofsyn-- chronously moving parts which are subiectto wear and loss of timing whereby the. apparatus often loses its eiiiciency, or even its operability,

the goods in the container.

It is improved piling or stacking apparatus for use in the orderly'stacking of textile rope in a container.

It is still another obiectof this invention to provide in a single'roller, means for forwarding textile goods and move the same both from side to side, and from front to back .of a container.

' Other objects of the invention will appear here- I inafter.

of the roller. I! the. external when taken in connection with the accomp'anying illustrations in which: Fig. 1 is a perspective cordance with the present invention, in .position Fig. 2 is a diagrammatic illustrate the manner inwhich it functions to move a rope. from front to back of the container.

Fig. 3 is a'perspective modified form of reverse grooved roller constructed in accordance with this invention.

Referring to Fig. 1, reference nates a rope-forwarding roller of elliptical crosssection. Roller 8 is journaled for rotation inthe top of a container ill. The roller shaft rotated by an electric motor or any other type of driving mechanism (not shown). The. roller 8 is provided with'reverse helical grooving I4 sufficient depth to traverse a textile rope from side to side of the container in. The grooves it must have a depth of at least inch and the button of the helical grooves, taken about the roller 8, must form an elliptical path circumferentially surface of the roller 8 is elliptical in cross-section, the grooves ll may have a substantially uniform depth, as shown in Fig. 1 of the drawing (except for possible slight non-uniformities in depth to prevent slipping of the rope from the groove or grooves as described I 1,749,355'and 1,918,210) and thereby providing a helically grooved roller in which the bottom of the grooves of the roller. The textile rope 18, consisting of continuous cloth goods, fiber is pulled by the roller 0 to forward the same to the container Ill. forth from side to side of the container by following the reverse helical grooveor grooves of roller '8. Since the'bottom of the helical grooves form an elliptical path circumferentially of the roller, the textile rope'is also to back of the container as it is, being traversed from side to side. The rope is therebypiled or stacked in the container 'in the manner shown. It is, therefore, readily ap ar nt that the single rotating roller 0, helically grooved as above described, is the sole operating member to forward and stack the goodsin the container I. in an orderly manner.

view of a portion of a numeral 8 desigl2 maybe form an elliptical bundles, or joined piece goods,

The rope is traversed back and.

thrown from front.

mmm mmm cally, how the roller a of m. 1 throws the textile 8 are shown as defining an elliptical path circumferentially of the roller. The distance X" represents the difference, at the forward side of the roller, between the short and long radii of the bottom of the grooves. The rope I6 is stacked from front to back of the container l0, even though the distance X is somewhat less than 'the width of the container, since it is caused to swing by the progressively changing contact of the rope with surfaces of the roller 2 having different radii. In the drawing, the roller 8 is shown positioned, relative to the container III, to place the distance X above the center of the container. Although this centered position of PX" above the container is generally pre-- ferred, in some cases the throw is not equal in 20, as shown in Fig. 3, has a cylindrical outer surface provided with grooves 24 of varying depth so that the bottom of the groove or grooves 24 will again form, about the roller, a circumferential path of elliptical outline, as shown by 22 which constitutes a projection of the bottom outline of the groove upon theface of the roller.

, A rope-stacking roller of this form willhave the i advantage that it ensures the maintenance of the rope in the grooves despite the throwing 2 effect of the elliptical bottom of the grooves, since grooves of greater depthare provided at that section of the roller from which the rope would have a tendency to jump the groove.

Round, reverse helically grooved rollers for 1 traversing of textile goods are well known in the art; such rollers being exemplified by U. S.

Patents Nos. 1,749,355 and 1,918,210. However,

. prior to this invention, when used in the traversing of textile goods which were piled or stacked in a container, it was always considered necessary to combine such a helically grooved roller 5 with a plaiting roller to move the goods from front to back of the container, as well as from side to side This necessitated a plurality of rope from front to back of the container Ill. The bottom I8 of the helical grooves of roller moving parts, moving synchronously-with each other to produce the desired result. By the present invention, the disadvantages entailed by a mechanism comprising a plurality of moving 5 partsare eliminated.-

The reverse helical grooving in the rope-forwarding rollers of the present invention may be constructed with any of the many known refinements for preventing the slipping or jumping of the textile rope from the groove or grooves. Since reverse helical grooving in rollers forzthe purpose of traversing textile rope is generally known, and since the specific construction of the hell-- cal grooving does not form a part of the present invention, details relating to specific reflne ments in the'groove construction are generally omitted from the present specification. In order that the reverse helically-grooved rollers of the present invention may apply the desired pull or tension on the textile rope, it may be desired to provide the same with surface characteristics which will impart the desired frictional pull on the textile rope. The surface within the grooves may, for example, be coated with a suitablesllghtly tackyresin or rubber composition, or it may be slightly roughened by sandeblasti'ng 'or by spray-coating with molten metal, orthe like. The grooves are preferably provided with slightly rounded corners to prevent undue-abrading, or even tearing, of the textile goods.

Since it is obvious that many other changes and modifications can be made in the detailsv above described without departing from the nature and spirit of the invention, it is to be under,- stood that the invention is not to be limited except as set forth in the appended claims.

I claim:

1. A textile rope forwarding roller having reverse helical rope-forwarding grooves in which 40 the bottom of the grooves, circumferentially of the roller, form an elliptical outline.

2. A textile ropeforwarding roller, elliptical in cross-section, warding grooves 'in which the bottom of the i grooves, circumferentiallyof the roller, form an elliptical outline.
