摘要： A yarn feed roller assembly for a tufting machine pattern attachment including a plurality of hollow drive shafts each having a plurality of feed rolls rotatably mounted thereon. An electromagnetic clutch having a rotating field keyed on the shaft within each feed roll selectively transmits the rotation of the shaft to the roll. Corresponding rolls of the drive shafts are drivingly connected one to the other. Between each pair of rolls is positioned a stationary yarn holding gear having teeth on only a portion thereof which bind with a corresponding gear on the other drive shafts and have yarn receiving grooves for surplus yarn when tufting with less yarn ends than the machine is capable of using. Slip rings located in a group at one end of each shaft receive electrical leads which pass through the shaft center from the clutch field coil. A horse shoe shaped brush retainer rides on each slip ring and is prevented from rotating by a quick release hook member which fits over a securing bar and is held in place by a spring member that also supplies the electrical power to the brushes.

摘要： A yarn guide comprises two or more closely spaced guide elements which define yarn-receiving pockets between successive such elements, the pockets being limited at the one end by a body part on which the elements are mounted and at the other side by a displaceable retention member. The retention member will usually be formed integrally with the related guide element and will be such as to be displaceable by a yarn moving transversely of its length into engagement with the pocket but relatively nondisplaceable by a yarn moving transversely of its length and outwardly of the pocket. The guide elements may be elongated in the direction of the yarns to be separated thereby to form plates between adjacent such yarns or they may take the form of pinlike members having not substantial length in the yarn direction.

摘要： Implementations herein describe an artificial turf having a backing layer and a plurality of rows of individual tufts tufted into the backing layer. Each tuft comprises at least three yarns per tuft and each one of the at least three yarns varies in at least one of material, color, texture, denier and cross-section. Each row of individual tufts is substantially similar to each adjacent tufted row and adjacent tufts on a given row are spaced apart at a predetermined gauge.

摘要： A multi-needle tufting gun for use in robotic tufting includes a support and a plurality of tufting modules mounted to the support, wherein at least one tufting module is movably mounted to the support such that the at least one tufting module is selectively spaced relative to at least another tufting module mounted to the support. Each tufting module comprises a tufting needle. A spacing actuator mounted to the support selectively moves the at least one tufting module relative to another tufting module, wherein the selective relative movement is in at least one axis across a tufting plane of a sheet of backing material to be tufted. In some examples, the tufting module includes self-contained tufting cartridges. There is also disclosed a tufting frame for conveying a backing material through a tufting area.
