1 The invention relates to weaving looms, and is of special application in the weaving of hat or strip material.

In the weaving of flat or strip material it is necessary that the strips forming the weft shall be fed through the warp with the same surface uppermost in each case. This cannot be'efiected when using Weaving looms employing a shuttle.

The invention has among its objects to provide a weaving loom in Which the use of a reciprocating shuttle is avoided; the construction of the loom simplified and the speed and efficiency of operation increased.

According to the invention, a Weaving mom is provided having a rotary Weft action which carries the weft thread or strip transversely across or through the warp into position in the woven product.

According to the invention moreover, a support to carry the weft may be provided as a beam or platform that is rotatable about a vertical axis and that supports one or more arm's rotatable upon a vertical axis positioned at the extremities of the beam or at the periphery of the platform, the said arms being geared to a stationary gear on the axis of rotation of the beam or platform in such manner that the arm "maintains its orientation during the rotation 'of the beam or platform, so that the arm or arms are presented normally or at a determined angle to the direction of the warp and serve in traversing the warp to carry the weft across the warp into position adjacent the last laid pick of Weft in the woven material.

According to the invention furthermore, a *single beam or platform may be used in co-operation with two warp frames or mechanisms, that is to say, two looms, that. are spaced apart to permit of the disposition and rotation of the beam or platform between them, and that lie parallel, the woven material on the frames being disposed at opposite ends; thus, the gripper arms for the weft thread or strips may be mounted .on a rotatable beam at a position adjacent the warp to retain their parallel relation in the rotation of the beam, and may be adapted to-engage'as by means of grippers the weft threads or strips which are supplied on endless conveyor mechanism at the opposite side of and parallel with the warp, means being provided to cut out the thread or strip and to move it into its final position in the woven material as by rotating'br'ushes or a swinging comb, and the movements of all the operating parts being synchronised with the rotational speed of the beam carrying thereonveyor arms.-

The rotatable beam may be 'rotatedb'y means of a gear wheel or the equivalent which is anchored to the beam and loosely mounted onits pivot, the central gear then serving to drive a chain of gear wheels mounted in driving engagement on the beam, and culminating in a gear Wheel at each end of the beam, to each of which end gear wheels avertical arm is secured, whereby in the rotation of the beam the gripper arms mounted on the vertical arms will always maintain their parallel positions while moving transversely of the warp'threads or strips.

The weft supplies may be wound on bobbins carried on an endless conveyor belt which is operated to move insynchronism with thelrotatable beam so that the weft strip or thread may be gripped by grippers secured to the ends of the arms and which may be synchronously operated to carry the strip or thread across the warp and to release it at or near its final position in the woven material.

The thread from the bobbin may belied through a tube or the equivalent mounted on the bobbin spindle so that the cut end of the thread i's'always in the same position in the tube to be gripped by the gripper arms. Means such as a light. spring or the equivalent maybe mounted in the time so as frictionally to retain the out .efid'of the bobbin thread in position to be gripped on each subsequent rotation of the gripper arms.

According to the invention furthermore, the weft supply may comprise instead of bobbins mounted to travel on an endless belt in a direction parallel to the warp, a magazine for the weft supply from which each thread may be fed by a piston or the equivalent at the appropriate time, to a position to be gripped by theg'r ipper mechanism. Guide members may be secured at the gripping position so that in the final .stage of its travel, the gripper mechanism is directed on an'exact path to grip-the weft-thread.

According to the invention, the gripper arms may be formed as tubular members to contain the means forlgrippingthe weft threads or strips. The gripper a-rms mechanism may comprisevertical rotatable tubular members mounted at or near theextremities of the rotatable beam or platform and horizontal tubular members secured as by welding, at the upper end of the vertical members, and thread or strip gripping jaws .inountcd at the projecting ends of the horizontal members operated through spring controlled rods mounted in the tubular members to open and close the gripping jaws at the appropriate times Any suitable means operated synchronously with the beam and conveyor mechanism may be provided to sever the weft strip or thread from its feeding bobbin.

Instead of the conventional swinging comb or reed for engaging the cut strip or thread to beat it up into its final position in the woven material, rotating brushes may be provided with their axes in alignment with the direction of. the weft strip or thread.

According to the invention furthermore, instead of rotating brushes or a swinging comb, the weft thread or strip may be caused to move into its final position in the woven product by bein passed between pairs of rollers mounted at opposite positions adjacent the edges of the warp with the spindle or axles oifset centre so that the threads or strips are frictionally gripped,

and a tension is applied to the weft threads or strips before they are cut.

Thus, the weft thread or strip is held under control while the shed is changing and locked in position on the reversing of the heddles.

The invention further comprises the features of construction hereinafter described.

The invention is diagrammatically illustrated by way of example in the accompanying drawings, in which:

Figure 1 is a perspective of one form of loom in accordance with the invention,

Figure 2 is a corresponding plan; the path of the weft arms being indicated in dot-and-dash lines,

. Figure 10 is a side elevation of Figure 9, and f Figure 11 is a fragmentary view of the finished product.

In carrying the invention into effect according 5 to the construction, illustrated in the drawings, the 100m includes conventional mechanism, such as heddles i for moving the warp shed, and means for taking up the woven material. The taking up means may comprise a feed roller or warp beam 2 from which the warp threads are carried. through eyes 3 in the pair of adjacently disposed hedclles I, which are vertically reciprocated by means of 'cam sectors 1', which may be rotated from the main drive of the loom in synchronisation with :the other operative and moving parts of the loom as hereinafter described. The woven material is then wound on a roller 5 after passing over a guide roller 6.

Instead of the usual shuttles for passing the 1 weft threads between the shed, the weft threads ,are according to the invention drawn between the warp threads by horizontal gripper arms 8 which are mounted at the upper ends of vertical supporting arms 7 carried at the extremities of a rotating beam, 9.

The beam 3 consists of upper and lower plates 55;, M respectively, held in spaced relation by distance members 52, and having mounted between the plates gear wheels l3, which at the centre engage a stationary gear wheel M fixed on the vertical shaft l5 about which the beam 9 1'0- tates, and at each end engaging gear wheels 46, secured on the ends of the arms 8.

The beam El is rotated by means of a worm wheel ll advantageously secured on the underside of the lower plate ll of the beam 9 by means of a worm is carried on a worm shaft i9 (Figure 2). The shaft [9 through chain and worm gearing 2@, 21 rotates the shaft 22 carrying the cam sectors s for imparting a reciprocatory movement to the heddles I.

It will thus be understood that in the rotation of the beam 53 about the central stationary shaft 45, the griper arms F, 8, are carried round on the ends of the beam 9, always maintaining their orientation.

The gripper mechanism (Figures 5, 6 and '7) comprises the

arms

7 and 8 formed as two tubular members disposed at right angles, one i, being vertical and the other 8, horizontal, and connected together as by welding, to present a continuous hollow passage of cylindrical section.

The vertical gripper arms l are mounted at or near the end of the rotating beam 9 in bearings and are in geared engagement through the gear wheel it with the gear wheels l3, it on the beam 9, through which, from the main drive, such as an electric motor 23, it is rotated relatively to the beam 9.

Concentrically mounted in upper and lower bearings 2 25 respectively, within the vertical gripping ar n l is a rod 28 of circular section, projecting at its lower end from the tube and carrying at its end a cam follower 2? which is adapted to engage vertical cams 28 formed on the periphery of a stationary circular plate 29, concentrically mounted with respect to the central shaft it about which the beam 9 rotates, and advantageously positioned beneath the beam.

The cams 28 may advantageously be formed with a gradual slope 3%; followed by a steep slope 3i for the purpose hereinafter described.

A downward pull is exerted on the rod 26 by means of a coil-spring 32 mounted at one end on an annular shoulder 33 formed at the lower end of the lower bearing 25 for the rod 25, and at the other end on the shoulder 35 of the cam follower 2!.

At the upper end, the cam rod 26 is provided of progressively decreasing diameter and extends through the upper bearing 24. On one part of reduced diameter 3"! of the rod 28 is secured a downwardly tapering or inverted cone The horizontal gripper arm 8 is or" a smaller diameter than the vertical arm 1, and is secured at the upper end of the vertical arm 5 at the upper end, in a position such that the rear end of a gripper-actuating rod 2S, which is concentrically mounted in the horizontal arm 3 bears against the wall of the inverted cone 3&3. The rod 26 is formed with a bevelled contact face 38 so as to be adapted to slide on the surface of the cone 35.

The gripper-actuating rod 2-5 is mounted in front and rear

cylindrical bearings

39, 39 respectively, in the horizontal gripper arm 3, a coiled spring 4!] being mounted between the rear bearing 39 and a collar ll secured at the rear end of the gripper-actuating rod 26 to maintain the bevelled face-of the end of the rod in continuous contact with the surface of the cone 3E.

' The forward bearing 39 for the gripper-aetuating rod 25 is mounted'to project beyond the end of the horizontal gripper arm 8 in the form of a nozzle 42 having a tapering :end'and a flat rectangular opening 53.

Thegripper jaws 4 3 are secured to the re" 'duced end-of the 'gripperactuating rod 25' and are formed as steel strips which in the normal position are urged bythe tapering form of the no'zzleto'lie with their ends adjacent each other, but not in contact.

The weft threads are carried on bobbins El which-are supported on a conveyor belt or chain '48 (Figures l and '2) operable by chain gearing 49, forming the main drive of the loom, thus ensur-i'ng synehonisation of movement. The "bobbins or weft'supply means are secured to the endless conveyor by any suitable connection which will positively position them during rotation of the endless conveyor. A bayonet connection or any othersuitable means known to the art may be used at this point. The bobbins i'i may be of frusto-conical form carrying at their upper ends a cylindrical projecting funnel 59 (Figures 6' and 7 through which the weft thread passes to project through a lateral opening 51 having guide members 52 flared outwardly at the ends 53 for guiding the ends of the grip-per mechanism when the thread is gripped.

In operation, the gripper arms i, S, are rotated relatively to the beam 9 and the horizontal gripper arm 8 is carried across or through the warp while maintaining its orientation.

,At the appropriate time, the weft thread is seized by the gripper mechanism, the cam follower 27 at this position travelling downwardly over an abrupt slope 3! on the cam 28 to draw the inverted cone 36 downwardly, thus forcing the gripper-actuating rod 26' forwardly whereby the gripper jaws A l, due to the restricted rectangular opening 33 in the nozzle '42 are caused to move together and grip the weft thread or strip. The weft thread or strip is then carried by the gripper mechanism across the warp, the bobbin feed continuing so that the weft thread is always held substantially at right angles or at the desired angle, to the warp, and is fed to rollers 54 (Figure at which position the cam follower 27 on' the cam rod 26 engages on the gradual slope Si), the cam 28 formed on the circular cam plate 29 which forces the cam rod 25 upwardly to permit the inward movement of the gripperactuating rod 26 and the gradual separation of the gripping jaws M to release the weft thread.

Immediately before the weft thread is released by the gripper mechanism, the thread passes between two pairs of skew rollers 5d mounted on a frame 55 between which rollers it is frictionally gripped. In its further movement into position the thread is severed by severing mechanism 58 of any suitable type known inthe art, and the free end simultaneously released by the gripper mechanism, to leave a length of weft thread between the rollers. The thread is then beaten up into position in the strip already woven by a swinging comb or reed, by brushes or in any suitable manner.

Instead of endless'conveyor mechanism for carrying the bobbins, the bobbins may be projected into the position for the thread to be gripped, or may be released under gravity to take up the appropriate position for the gripping of the thread.

The rollers *54, due' to their being mounted with their. spindles or shafts set at an angle: serve to maintain the thread or strip undertension.

In Figure ll there is shown a fragment ofmaterialwoven from flat'strips. By using a number of bobbins, a variety of threads or strips-of dif- 'ferent colours may be used.

It will be understood that in the loom accord- I ing to the invention there'is no'twisting 'of' the thread as in known weaving looms-operating looms using the flying shuttle.
