Abstract: A dust control and cooling apparatus for use in connection with a circular knitting machine includes a flexible manifold which sits upon the knitting machine table and encircles the needle cylinder. A series of nozzles directs pressurized air applied to the manifold towards the needle cylinder to remove lint and dust from the operating surface and cool the components. The manifold assumes a generally flat configuration when not operating, allowing access to the enclosed area without removal of the manifold. When operating the manifold inflates and expands upwardly towards the overlying sinker ring, sealing the enclosed volume and allowing a positive pressure to be generated therein. This positive pressure helps prevent the further ingress of lint and dust into the enclosed volume.

In another embodiment, without plates, the protrusions on the web are disks and the areas between the disks are covered by other disks.

Abstract: An air interlacing jet 2 includes a yarn channel 20 and a threading slot 42 forming an opening on one side of the yarn channel so that yarn or yarn filaments can be inserted into the yarn channel. An air orifice 40 intersects the yarn channel and high pressure air injected through the air inlet or orifice 40 interlaces or intertwines the yarn or yarn filaments as they are drawn through the yarn channel 20. The body 4 of the interlacing jet or jet insert 2 is a single piece member and the yarn channel 20 includes outwardly tapered sections 28 and 32 at each end. The tapered sections are formed by an EDM process. Thread guides 58, 60 located below the yarn channel axis and the tapered yarn channel sections permit the yarn to be drawn through the yarn channel 20 at an angle relative to the threading slot 42 so that the yarn cannot easily escape from the yarn channel 20.

Abstract: A warp knit, weft inserted fabric substrate for use as a strength component in vinyl coated and laminated backlit signs, awnings and in other applications where stability and uniform geometry is desired. The stable knit construction of the fabric is achieved by doubling the number of stitches or courses per inch of fabric. To avoid changing the industry-wide standard fabric construction of 18x12 with the stitch doubling, weft yarns are inserted every other stitch. In a fabric having an 18 x 12 construction, the number of stitches doubles from 12 to 24. The final fabric construction is 18 warp ends per inch, 12 weft ends per inch, and 24 courses per inch. Although the course count increases from 12 to 24 stitches per inch, only one weft yarn is inserted for every two stitches rather than every stitch as currently done in the prior art. By doubling the number of stitches through shortening the stitch length, the weft or filling yarns area forced to remain in a restricted are of the fabric.

Abstract: A seamless brassiere, and methods and blank for making the brassiere are described. In particular, a tubular blank is circularly knit, and first and second walewise extending longitudinal openings are formed along opposite sides of the blank, to form torso and neck openings for the brassiere. The blank ends are trimmed, if desired, to form the desired contour for the arm openings, then banding is applied to each of the torso, neck and arm openings, to thereby form a finished brassiere. At least the banding secured to the torso opening is elastic, in order that the garment may be secured closely about a wearer. In the finished seamless brassiere, the courses extend vertically, while the knit wales extend horizontally when the brassiere is worn, which provides an enhanced level of support for the wearer's breasts.

Abstract: In the case of an arrangement for transporting at least one thread treated in a thread conditioning plant from a delivery roller pair to a transport belt which takes up the thread in the form of thread loops, an adapter is arranged downstream of the delivery roller pair, with which adapter it is possible to equip the arrangement as required with a stuffer box or an oscillating loop laying device. By simply exchanging an aggregate it becomes possible, depending on the type of operation required, to crimp and heat set threads or to treat uncrimped threads.

Abstract: Armor, in particular body armor for female wearers is made of multiple layers (30) of penetration-resistant material for example made of polyaramid fibers, specially shaped to fit over a shaped area to be protected, e.g. the bust of a female wearer. The armor's shaped part is held in shape by a series of darts (37) in successive layers (30) of the material. Each dart in a material layer comprises a generally V-shaped section (35) whose edges (37) are joined to form the dart. The V-shaped section (35) of the material is folded on itself to form a pleat (40) which is folded over to one side of the dart (37) to form an added thickness overlaying or underlying an adjacent part of the material (30). The darts (37) are angularly offset from one another with the pleats (40) oriented in directions so that the added thickness is distributed substantially evenly, thereby avoiding bulges or stiffness and improving the wearing comfort.
