Circumferential yarns and radial yarns are laid in helical courses and woven into said network of rods around the axis.

Abstract: A baseball mitt comprising front and back plies forming a mitt body having thumb portion, a finger portion and a portion connecting the thumb and finger portions, and a glove secured to the back of the body with the front of the glove facing the back ply. The glove has a thumb stall disposed generally behind the thumb portion of the body, at least one finger stall disposed generally behind the finger portion of the body, a crotch portion between the thumb and finger stalls, a palm portion, and a hand-receiving opening adjacent the bottom of the mitt. The glove is joined to the mitt body at the periphery of the hand-receiving opening and at the ends of the thumb and finger stalls, but is free of attachment to the body at its palm portion, thereby providing freedom of movement of the palm portion of the glove relative to the mitt body for increasing the flexibility of the mitt.

Abstract: The ribbon-type fabric is provided with weft-yarn loops inserted at both sides of the run of the warp yarn, the weft-yarn loops being held together at the two edges of the ribbon-type fabric by at least one auxiliary yarn. In order to avoid that the joints of the weft-yarn loops are visible to the exterior, the auxiliary yarn will run parallel to the weft-yarn loops over at least a part of the width of the ribbon-type fabric. The auxiliary yarn is tied-off in itself or by means of an additional auxiliary yarn.

Abstract: An improved method and apparatus for jetting auxiliary fluid to a fluid and filling guide passage formed on a sley in a jet loom wherein a plurality auxiliary nozzles are vertically disposed at predetermined intervals to confront the opening of the guide passage, the entire region in the direction perpendicular to the longitudinal direction of the opening of the guide passage is covered by the auxiliary fluid jetted from the opening of the respective nozzles.

Abstract: A yarn delivery device is provided for textile machines, particularly for air jet looms. A knotcatcher is provided with a measuring drum that reduces frictional drag on the yarn thus reducing the air requirements for pulling the yarn off the drum, reduces the wear on the yarn contact points, has longer life, and is easier to repair than conventional knotcatchers. The knotcatcher includes a circular plate having a circular axially upstanding circular rim, with a plurality of smooth-surfaced hardened steel cylindrical pins upstanding from the rim. The pins are press fit into holes formed in the rim, and if damaged may be readily replaced.

Abstract: A weaving heddle includes an elongated heddle shaft having U-hook shaped end loops at opposite ends for holding the heddle on opposed heddle carrying rods of a heddle frame. The loops include shanks for overlapping with the rods, and the loops have inner support surfaces spaced a predetermined distance apart and extending transversely of the shaft for engagement with the rods. One of such support surfaces is resiliently biased toward the other of such surfaces for accommodating any increase in such predetermined distance.

Abstract: The catch mechanism employs a straight line guideway for moving an ejector reciprocally in a straight line path. The ejector has a foot piece for engaging only the foremost gripper projectile of a series of projectiles in a channel so as to positively eject the foremost projectile. A pivotally mounted spring biased pawl is used to retain the projectiles in the channel and is biased outwardly during an ejection process by the movement of the ejector.

Abstract: A transfer device comprises a transfer lever arranged to execute an oscillatory movement and carries a thread clamp at its free end. This thread clamp comprises a leaf spring constituting a movable, controllable clamping element. The leaf spring can be raised by an actuating lever pivotally mounted on the transfer lever and which is movable relative thereto. At least one thread pick-up or entrainment element and preferably two thread pick-ups or entrainment elements, are arranged on the batten of the loom to position the weft or filling thread in the thread clamp in a predetermined position. This arrangement constitutes a relatively very simple, operationally reliable and self-cleaning transfer device.

Abstract: Actuating device for the reciprocating movement of the belts carrying the weft thread insertion grippers in shuttleless looms. Each belt is provided with a lengthwise series of slots and with the slots of one series a respective gear wheel is in mesh engagement. An oscillating gear sector drives the gear wheel. The gear sector has along the bisecting line thereof a slotted link coupling including a slider. The coupling provides articulation both with the big end of a connecting rod in a crank mechanism, which is driven by a cyclic shaft of the shuttleless loom, and with the pin of a rocker arm following the oscillations of the gear sector.The law of motion determined by the cooperation of the slotted link coupling and the slider causes variation of the transmitted speed, acceleration and stroke, particularly near the two dead points of oscillation of the sector thereby improving the operations of the grippers to which such motion is transmitted.

Abstract: The invention comprises a fully adjustable and pivotal support for a warp stop-motion which may be finely adjusted to its optimum operable position and then pivoted upwardly and out of the way when desired, as while changing the warp beam, and instantly and accurately retured to said optimum operating position by means of a positive stop which positions the warp stop-motion mechanism in said optimum operative position automatically without further attention by the operator except to tighten the few bolts necessary to hold the warp stop-motion mechanism in said optimum operating position.

Abstract: A thread brake for a textile machine, in particular a shuttleless loom, in which weft thread lengths are withdrawn from a store disposed outside the shed, wherein interruption of weft thread take-off is carried out by displacement of a take-off roller 6 rotating at constant peripheral speed from an operative position to an end position remote from the thread 1. The device comprises at least for one brake shoe a movable holder 21 which is movable between two end positions in the direction of the gap towards a holder 21' of the other brake shoe and at least indirectly connected to the loom shaft 8 in driving relationship. The displacement of one or each holder occurs against the force of a spring 23 or 23' which in the unloaded state corresponds to a distance between the two brake shoes corresponding to thread thickness.

Abstract: A device for shedding warp yarns in a weaving loom, such as a jet loom, comprises: cranks supported on machine frames of the loom rotatable in synchronization with the weaving operation of the loom; synchronizing levers swingably pivoted; connecting rods connecting the cranks with synchronizing levers so that the rotational movement of the cranks is transmitted as a swinging motion of the synchronizing levers; synchronizing links linked with the synchronizing levers; rocking levers linked with the synchronizing links so that the rotational movement of the cranks is transmitted as a swinging motion of the rocking levers through the swinging motion of the synchronizing levers; and heddle frames, for the upper and lower warp yarns, operated by the rocking levers.

Abstract: A dobby mechanism with a coupling, controlled according to a design, between a stationary drive shaft and a first gear with the number of teeth n, which first gear meshes with a second gear with the number of teeth 2n on a stationary axle, on which second gear an eccentric device for the dobby movement is arranged, whereby the drive shaft and the first gear are coupleable with each other by means of a radially movably mounted wedge, which wedge is controlled with a switching member from the outside according to a design, and in the coupled condition partially engages in a radially extending recess of the first gear and partially in an axially extending groove of the drive shaft. In the uncoupled condition the wedge is completely uncoupled from the drive shaft and the switching member comprises a switching rod, the latter being controlled according to the design, the switching rod in the coupling range engaging with a coupling member in a groove of the wedge.
