18 Claims. (Cl. 28-32) The present invention relates to textile beaming or warping apparatus, and particularly, to a method and an apparatus for collecting simultaneously the portions which are not acceptable for the manufacturing of fabric from a large plurality of yarn supply packages.

beaming practice which is increasing rapidly in commercial importance involves warping directly from rayon cakes obtained by collection in centrifugal buckets. The entire content of several hundred to a thousand or more packages, except for the outer portions thereof which contain yarn of inferior quality, is collected into a single beam in a period of a few hours.

However, in beaming yarn from packages in which the yarn is originally wound, particularly from cakes of viscose rayon yarn, it is desirable to unwind and discard the outer layers of the packages. One to two hundred yards of yarn are normally removed from each cake of viscose yarn. Heretofore, the initially unwound inferior yarn has been collected on a beam barrel, the machine then stopped, and the inferior yarn stripped from the barrel before proceeding with the beaming of the yarn of acceptable quality. In addition to the loss of operating time incurred during the yarn stripping operation, a further disadvantage is incurred, i. e., the surfaces of the beam barrels are damaged by sharp yarn-severing implements used to strip the waste yarn. The increased use of all metal beams comprising a light soft metal such as aluminum or magnesium has added to this hazard. it is important to maintain a smooth and continuous surface on the beam barrel or the yarn next to the barrel will be abraded, and/or the windings of one layer will become tangled with the adjacent layers.

It is an object of the present invention to increase the productivity of beaming equipment and the operating personnel therefor. It is another object to provide apparatus ancillary to a beaming apparatus for the purpose of collecting a section of the yarn ends passed through the beaming apparatus independently of a beam supported therein. It is still another object of the invention to provide a single apparatus to be used in conjunction with one or more beaming machines for collecting yarn of inferior quality in a single mass through a series of beaming machine dofling operations Without stripping the yarn from the apparatus each time a machine is dotted, such apparatus being constructed so that an accumulation of the yarn may be readily stripped from it. Still another object is to reduce or eliminate the damage to beam barrels which is ordinarily sustained in removing waste yarn therefrom. Other objects, features and advantages will be apparent from the following description of the invention and the drawing relating thereto in which Fig. 1 is a diagrammatic view in elevation of a beaming machine and auxiliary apparatus for receiving yarn;

Fig. 2 is a pictorial view of the auxiliary apparatus of Fig. l; and

Fig. 3 is a diagrammatic view in elevation of modified auxiliary apparatus for receiving yarn from a beaming machine or creel.

In accordance with the present invention, a take-up device for a large plurality of yarn ends is driven and supported adjacent to a beaming machine and the beam supported therein. The take-up device receives and stores a section of the yarn-sheet from a plurality of sources. The take-up device and the mounting therefor is preferably portable. or mobile so that it may be readily moved intoand out of operating positionv with respect toone 2,694,848 Patented Nov. 23, 1954 or more beaming machines. In a preferred form of the invention, the take-up device comprises a roll, barrel, or drum provided with a longitudinal groove along its peripheral surface to facilitate the stripping of yarn therefrom and the mounting for the roll or drum is provided with a receiver for the severed yarns.

As illustrated in Fig. 1, yarns 4 pass into a beamer 5 from a supply means such as a creel (not shown) which supports several hundred to a thousand yarn packages such as cakes of regenerated cellulose rayon yarn. The yarns 4 advance as a single sheet of parallel yarns between guides 7, through separate elements of the electrical drop wire device 8, a comb 9, and over a measuring roll 10. The yarn in normal operation of the beaming machine passes from the roll 10 to a beam 12 Sup ported on a pair of arms 14 disposed at opposite sides of the machine and extending from a pivot bar 15. The beam 12 is swingable with respect to the pivot 15 into engagement with a pressure roll 16 driven by a motor 17 through an intermediate drive transmission. The beamer 5 is briefly described and is constructed according to well-known beaming machine design. Beaming machines of other conventional designs may be substituted for the one shown.

In accordance with the present invention, apparatus 20 comprises a drum 01' barrel mounted in a movable frame driving motor 23. rotatable shaft an auxiliary 21 rotatably 22 which supports also a The barrel 21 is supported on a 24 coupled directly to the shaft of the motor 23. The barrel is provided with a groove 25 which acts as a guide for the knife or other severing instrument used by an operator and moved along the groove in a direction lengthwise of the barrel to strip "yarn from the guide. A container 27 is supported between standards 28 and 29 of the frame for receiving the yarn stripped from the barrel. The electrical power passing to the motor 23 is preferably adjustably controlled by a current-regulating means such as the rheostat-type controller 31. The controller may be provided also with a reversing switch 32. Electrical power is transmitted to the controller through an extension cord 33 provided with a conventional terminal fixture 34 which may be plugged into or otherwise connected with any convenient electrical outlet such as one provided on, or closely adjacent to, the beaming machine 5. If preferred, a collection of yarn on the barrel 25 may be removed by reversing the motion of the barrel through operation of the switch 32 to unwind the strand collected on the barrel into the container 27.

The auxiliary apparatus of Fig. 2 is mounted on casters 35 so that it may be easily moved into and out of operating position adjacent a beaming machine 5. Positioning plates or bumpers 36 are secured to the frame 22 for the purpose of engaging reference surfaces, such as those of the toe portions 38 of the beamer frame at opposite sides thereof.

in operation, the apparatus of Fig. 2 is brought into the position shown in Fig. l. The beaming machine is threaded with the strands 4. To facilitate the transfer of the strand ends to the auxiliary apparatus, an adhesive tape may be laid across the portion of the sheet of parallel or juxtaposed strands supported on the upwardly-facing portion of the cylindrical surface of roll 10. The ends are then readily transferred as a group to the barrel 21. The rotation of barrel or drum 21 may be commenced at slow speed until at least one revolution thereof is made and the yarn portions passing onto the barrel firmly overlap the tape, and the portions joined by the tape to secure the yarn to the barrel. The barrel thereafter may be rotated at any desired speed until the necessary yardage has been removed from the strand packages supported in the creel. After such yardage has been Withdrawn from the creel, the rotation of barrel 21 is stopped in preparation for severing the yarn at some point between roll 10 and barrel 21. However, so that the severed yarn ends may be easily transferred to the barrel or beam 12, they are secured in some manner prior to severing so that they may be easily handled as a group when delivered into thebite of the engaging cylindrical surfaces of the barrel l2 and the driving. roll 16. Portions of the yarns near the severed ends may be secured together by an adhesive tape applied along roll or along barrel 21 prior to transferring the ends to the barrel of the beam 12, or groups of the strands may be knotted together.

Fig. 3 illustrates a modified yarn-collecting apparatus 40 utilizing a different take-up mechanism than that illustrated in Figs. 2 and 2. A pair of nip rolls 41 and 42 receive the yarn sheet 43 from a beaming machine such as illustrated in Fig. 1, and discharge the yarn mto the hopper 45. The roll 41 is driven by a motor 46 which may be connected therewith in the manner described for connecting the roll 21 with the motor 23 of Fig. 2. The rolls 41 and 42 are rotatably supported within a frame 48 which also supports the hopper 45 and the motor 46. The frame is preferably mounted on casters 49 which permit the apparatus 40 to be easily moved. The frame 48 is provided with a pair of positioning plates or bumpers 50 adapted to engage frame portions of a beaming machine in engagement with the toe portions of a beaming machine.

Slight modications may be applied to the auxiliary yarn-collecting devices of Figs. 2 and 3 to adapt them for use with any type of beaming machine so as to eliminate the time-consuming operation of stripping yarn from the beam barrel normally mounted in the beaming machine for collecting the yarn intended for use in the manufacturing of fabrics. As a further advantage, such barrels which in many cases are metal are thus protected from cuts or abrasion or other damage that might injure or tangle the yarn wound thereon. Moreover, the auxiliary yarn collection device permits the accumulation of many loadings of waste yarn thereon before stripping is necessary. As a further advantage, the stripping of waste yarn from creel supported packages is carried out with optimum accessibility to the waste yarn collecting device and a resultant saving of labor and greater convenience to personnel in conducting the stripping operation.

While preferred embodiments of the invention have been shown and described, it is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined in the appended claims.
