摘要： Tufting apparatus for producing textile goods includes a plurality of hollow needles (10) which are reciprocated vertically to penetrate a backing (12). A selected yarn (92) is fed pneumatically through a respective passageway (102) into a yarn exchanger (70) and through a respective needle and implanted into the backing, the backing being shifted transversely so that a transverse row of tufts is implanted across the backing. There are a series of passageways (102), each carrying a different yarn, communicating with each yarn exchanger. The selected yarn is fed by a yarn feed system and carried by high pressure air flowing in the passageway of the selected yarn, the yarn exchanger and the needle, while air flows in the other passageways under a lower pressure. The yarn exchanger has a funnel shape configuration (108) and when a particular yarn is selected to be fed to the needle, another yarn is withdrawn from the needle to the inlet of the funnel. In order to prevent tangling of yarn within the funnel to preclude clogging at the inlet of the nozzle, an air jet is supplied within the funnel directed toward the inlet of the needle, the air jet being a nozzle (112,114) positioned within the funnel.

摘要： Apparatus for producing tufted textile goods employs a plurality of hollow needles which serve as backing openers (10), the backing openers being carried on a widthwise extending member (70) which is reciprocated in a vertical direction to cause the backing openers to penetrate a backing. Yarn (92) is transported pneumatically through the backing openers and implanted into the backings as yarn tufts, the backing being shifted in the transverse direction by an amount corresponding to the spacing between adjacent backing openers in order to implant a transverse row of tufts. Each yarn is trained about a feed roller (82) which is selectively moved into peripheral engagement with a drive roller (80) when the yarn is to be fed to the needle. The yarn transverses a path from the feed roller to the needle which includes a yarn clamp (109) and a yarn pullback mechanism (96,99,101). When yarn is being fed the clamp is released and the pullback mechanism provides a first path for the yarn to travel to the needle, but when that yarn is no longer to be fed to that needle, the clamp is actuated to clamp the yarn and the pullback mechanism thereafter draws the yarn back from the needle into a second and longer path, and the feed roller is disengaged from the drive roller.
摘要翻译：用于生产簇绒纺织品的设备采用多个中空针，其用作背衬开口（10），背衬开口被承载在沿垂直方向往复运动的横向延伸构件（70）上，以使背衬开口穿透背衬。纱线（92）被气动地穿过背衬开口，并作为纱线簇移动到背衬中，背衬沿横向移动相应于相邻背衬开口之间的间隔的量，以便植入一排横向刷毛簇。每个纱线围绕馈送辊（82）进行训练，当进给纱线被送入针头时，该进给辊被选择性地移动到与驱动辊（80）周边接合。纱线横跨从进给辊到包括纱线夹（109）和纱线拉回机构（96,99,101）的针的路径。当进给纱线时，夹具被释放并且拉回机构提供纱线行进到针头的第一路径，但是当该纱线不再被供给到该针头时，夹紧器被致动以夹紧纱线和回拉机构此后将纱线从针头拉回第二和更长的路径，并且进给辊与驱动辊分离。
