摘要:
A tufting machine for selectively forming tufts of yarns, including different color or type yarns, for forming patterned tufted articles such as carpets. A series of needles are reciprocated into and out of a backing material being fed through the tufting machine and are engaged by a series of gauge parts so as to pick-up loops of yarns from the needles. The gauge parts will be selectively controlled by activators to extend or retract the gauge parts to positions or elevations sufficient to pick-up or not pick-up loops of yarns from the needles. The feeding of the yarns to the needles further will be controlled to back-rob yarns not picked-up by the gauge parts, while the backing feed will be controlled to enable formation of tufts at an increased rate over the pattern stitch rate for the pattern of the tufted article being formed.

A level cut loop looper or hook and clip assembly for a tufting machine includes at least one module carrying a series of level cut loop loopers or hooks. Each level cut loop looper or hook generally can include a looper body along which a clip is slidably moved. Each clip will be moved between retracted and extended positions as the level cut loop loopers or hooks are reciprocated toward and away from engagement with their associated needles of the tufting machine. Actuators can be engaged to secure the clips in their extended positions as needed to selectively form cut and loop pile tufts in a backing material.

摘要:
A tufting machine that includes spaced rows of needles of inserting yarns into a backing material. The needles are engaged by opposed loopers and level cut loop pile hooks that pass between one another so as to engage the opposite row of needles for forming cut pile and loop pile tufts of yarns in the backing material.

A hook module assembly for a tufting machine is provided that allows for broken and damaged hooks of a level cut loop tufting machine to be replaced. The hook module assembly includes modular blocks having a series of slots in which level cut loop hooks are received. Locking mechanisms secure the hooks within their respective slots in the modules and allows for removal of individual hooks from the module as needed for repair and replacement.

A tufting machine includes a hook apparatus, which has gates and hooks. The hook apparatus has connectors that are coupled to the gates and actuators. The actuators can be actuated to move both the connectors and gates.
摘要:
A multi-cylinder module has a common block within which the cylinders are formed and having a piston disposed within each cylinder and an output rod connected to each piston. Pressurized air acts on the piston against the bias of a corresponding spring to drive the respective rod outwardly from the module. Each rod has a coupling member which is coupled to the gate of a hook of a tufting machine having gated hooks for forming both loop and cut pile. The modules are mounted directly to the hook bar of the tufting machine and require no additional linkages between the coupling and the gate with the inherent lost motion and other inefficiencies associated with such additional linkages.

A tufting process is provided whereby one pile length is cut from a pile material which is to be joined to a backing material by means of a cutting edge after the formation of each loop. Provision is also made for the cutting process to be effected by means of the vibrational cutting movement of a cutting edge, in particular with the aim of improving the cut and reducing wear. In order to implement such a process, a tufting device is provided which incorporates a row of side by side loopers. The loopers move to-and-fro for the purpose of looping the pile material. Each looper includes a base installed in a looper block. A shaft extends from the block and has a nose for collecting the yarn on its front end. The shaft further incorporates a cutting edge configured so as to perform the cutting process. Each looper is adapted to be coupled with a vibrating drive which superimposes a vibrational motion on top of the to-and-fro motion.
摘要:
A knife holder apparatus for a cut pile tufting machine including a knife block fixed to a depending mast which is slidably mounted within a corresponding slot in the knife bar and a wedge clamp member adapted to clamp or lock the knife bar carrying a plurality of knives in an operative position relative to the knife bar in which the knives cooperatively engage their corresponding looper hooks. The knife holder apparatus supports the knives at their predetermined tension and pitch angles relative to the looper hooks and in a manner in which the knife holder module and knives may be easily and quickly removed and replaced.
摘要:
A group of knives for a cut pile tufting machine are preassembled in a knife holder carried by a bracket, as the bracket is held in a jig. The bracket is then removed from the jig and inserted into one of a plurality of transverse parallel angling slots in a carrier member of the machine, the knives and bracket being moved in a linear path until a stop on the bracket engages the carrier member to indicate that the knives are in proper position for cutting action with respect to their loopers.
