Abstract:
A system and method for forming synthetic/artificial grass or turf products in which a series of tufts of artificial/synthetic grass filaments or yarns are formed in a backing material with various graphic pattern effects being formed therewith. The system generally will include at least one needle bar having at least one row of needles mounted along a tufting zone and reciprocated through the backing to a desired penetration depth, and will present a desired set or group of yarns to a series of pattern pixels or stitch areas. A series of level cut loop loopers or hooks will be aligned with and will engage the needles in order to form tufts of yarns in the backing material. Clips of the level cut loop loopers will be selectively controlled to control the retention of selected ones of the yarns presented at each pattern pixel. The remaining, non-selected yarns generally are not retained at the pattern pixels, and can be formed as lower pile tufts or removed from the backing material.
Abstract:
A method for binding a greige carpet and a secondary backing material using a hot melt adhesive is disclosed. A heated application roll may be provided and the secondary backing material may be contacted with the hot melt adhesive and greige carpet and pressed against the heated application roll.

Abstract:
A simple, convenient and cost-effective method for making a three-dimensional embroidery, comprising the steps of: (1) providing layers of fabric comprising a base layer, a top layer and an intermediary layer of a thickness; (2) embroidering a pattern through the layers of fabric with thread; (3) cutting the intermediary layer at a height to separate the top and base layers; and (4) removing the remaining intermediary layer from at least one of the top and base layers.
Abstract:
The invention relates to an optical fiber sewing apparatus for sewing optical fibers into a material workpiece and the methods of manufacturing the products using the optical fiber sewing apparatus. According to the present invention, the optical fiber sewing apparatus comprises comprising; a fixed plate 50 which is fixed to the lower section of said sewing head 20; a pushing plate 60 which is fixed on upper section of said fixed plate 50 wherein said pushing plate 60 is moved up and down by a pushing plate transfer cylinder 61 and said pushing plate further comprises a insertion groove 63 to which a needle holder 31 is inserted and a guide pipe 64 is constructed at the lower section of said insertion groove 63; a cutter 70 which cuts the optical fibers 5 and located at the lower section of said fixed plate 50 wherein said cutter 70 moves on a horizontal direction by a cutter cylinder 71 in order to cut the optical fibers 5; a material workpiece table 100 which is located at the lower section of said cutter 70 in order to support a material workpiece 9 with a plurality of supporting blades 120; and wherein said optical fibers 5 is provided through the eye of the needle 30 from a optical fiber spool via a tension control section 10 and elastic body 6. The optical fiber sewing apparatus according to the present invention, the optical fibers are more precisely sewed onto the material workpiece, the optical fibers are provided without being entangled and the material workpiece is not lifted when the needle is removed.
Abstract:
A portable hand-held apparatus for inserting one or more optical fibers into one or more insertion points in a flexible or semi-rigid panel having a uniform planar surface, positioning and adhering the fibers at the insertion points, playing out a pre-selected length of fiber and cutting the fibers at the selected length for collection in groups or bundles for attachment to one or more illumination devices.
Abstract:
The machine comprises a frame (1, 2, 3, 4), a rotary mandrel (15) mounted on a horizontal shaft (14), a vertical arm (12) having a detachable work device (20) at the lower end of the arm, and means (M1, M2, M3) for shifting the arm (12) along three orthogonal axes (X, Y, Z).
Abstract:
A self-threading stitching device for joining uncured composite laminates which comprises a vertically mounted needle shaft adapted for reciprocal motion, a thread feeding means operating synchronously with the needle shaft and self-threading needle means adapted to pick up the thread from the thread feeding means and carry the thread through uncured composite laminate being penetrated by the needle and release the thread in the laminate as the needle withdraws therefrom.
Abstract:
Weatherstripping is produced continuously by two or more spaced apart tufting heads, which may be operating at different stitch rates. The or each strip of weatherstripping comprises at least two rows of tufts sequentially inserted by two tufting heads. Heated dies may be located between the tufting heads for transforming rows of tufts inserted by the first tufting head at least partially into film to form barrier fins. The knuckles of the tufts are flattened, a secondary backing applied, and then individual strips of weatherstripping separated by ultrasonically slitting, all as a continuous process enabling weatherstripping of various constructions to be efficiently and economically produced by tufting.
Abstract:
A carrier for holding pieces of yarn ready for use in making rugs and similar articles by hand comprises a perforated flexible sheet of pliable material such as strong paper. The ends of individual pieces of yarn of predetermined length extend through the perforations, with each piece of yarn bent into a "U" shape so that both ends of each piece are on the same side of the fabric sheet, but the two ends of each piece extend through different perforations. The pieces of yarn may be mechanically inserted into the sheet in locations corresponding to the locations of the pieces of yarn in the article to be made by hand, giving a preview of the appearance of the article and serving as a pattern for the handmade article.
