Description

The present invention relates to the manufacture of veil with an improved pile thread pin.

  Conventionally, in a vegetation manufacturing apparatus using a scissor rod, a hook is provided at the tip of the scissor rod, and the pile yarn hung between the back warp yarns is hooked by the hook while rotating the scissor rod. It is designed to be spirally wound around the bayonet.

However, since the boundary between the hook and the base of the scissor rod is the same thickness as the scissor rod, there is no looseness in the pile thread and the scoop rod that is wound, so it resists the rotation of the scissor rod As a result, static electricity is generated and tightened, and depending on the type of material, a hard pile yarn or the like generates even greater resistance, creating a load on the entire winding drive unit and significantly improving work efficiency. Reduce.
In other words, in order to increase the efficiency of work during the manufacture of the veil, it is most desirable to shorten the time of the winding process of the pile yarn, but for that purpose it is necessary to increase the number of rotations of the scissors as much as possible. It becomes. However, in the case of the conventional hook, the pile yarn and the stake bar that are tightened are tightened, and there is a possibility that a load more than necessary is always applied and the smooth operation cannot be performed.

In addition, since there is a step between the hook base and the tip of the swivel rod, there is a risk that the pile yarn may be wound or caught carelessly, resulting in poor working efficiency.
Japanese Patent Publication No.42-18588

  Accordingly, the present invention provides a veil manufacturing apparatus provided with a scissor rod having a low work efficiency and capable of smooth winding work with less resistance when the scissor rod is rotated and without causing the pile yarn to be caught inadvertently. It is something to be offered.

Pile yarn is laid on multiple back warp yarns in parallel, and the pile yarn between the back warp yarns is spirally wound around a scooping rod that advances while rotating, weft insertion, beating, reverse opening in carpet manufacturing apparatus for performing a Karamitsuke the leno thread, a root portion of the hook provided at the tip of Mekukomi bar while thicker than the thickness of the narrowing winding rod, the base portion near the boundary portion of the rod narrowing winding with the top of the hook together with the introduction portion to prime the rising curve graded thicker than the thickness of the Mekukomi rod, the distal end surface of the hook directly and the distal end surface of the narrowing winding rod or indirectly wound pile yarn as a flush This is a vegetation manufacturing apparatus that can be freely inserted into a dowel bar .

As an effect of the present invention, the pile yarn that is spirally wound by the rotation of the swaging bar is spirally wound in the initial introduction portion to a size having a margin with respect to the thickness of the swaging bar, and this large Since the wound material sequentially moves to the scooping rod, the pile yarn is wound around the scooping rod in a generous state, and the work load can be reduced to increase the work efficiency. Further, since the tip end surface of the hook is flush with the tip end surface of the swaging bar directly or indirectly, there is no risk of the pile yarn being caught inadvertently and a smooth operation can be performed.

The back warp yarns 1, 1 and the front warp yarns 2, 2 are opened, and pile yarns 3 are laid on a plurality of the back warp yarns 1, 1 that are open and arranged in parallel, and the pile yarns 3 between the back warp yarns 1, 1 In the veil manufacturing apparatus for winding the swivel rod 4 in a spiral manner in order, the weft insertion rod 5, the beating, the reverse opening, and the entanglement of the kneading yarn 6 , The base portion of the hook 7 provided at the tip is thicker than the thickness of the swaging rod 4, and the boundary between the top of the hook 7 and the base portion of the swaging rod 4 rises thicker than the thickness of the swaging rod 4, and is curved. with the introduction portion 8 which graded, those freely Mekukomi the rod 4 narrowing winding the pile yarn 3 tip surface of the hook 7 with the distal end surface and directly or indirectly flush the wound narrowing rod 4 It is.

The illustrated hook 7 is provided on the swivel rod 4 via a detachable attachment assisting tool 9. In this case, the tip surface 9 ′ of the assisting tool 9 and the tip surface 7 ′ of the hook 7 are wrinkled. When the hook 7 is provided directly on the swaging bar 4, the front end surface 4 ′ of the swaging bar 4 and the front end surface 7 ′ of the hook 7 are directly flush with each other.

The base portion 7 ″ of the hook 7 is substantially the same as the thickness of the fitting rod 4 or the attachment aid 9 to be attached, and wraps the outer portion.

  The thickness and length of the introduction portion 8 vary depending on the material and thickness of the pile yarn to be used, but are set to a length at which the pile yarn is wound at least one turn.

  FIG. 3 shows a state in which the scissor bar 4 is pulled out after the pile thread 3 is wound around the scissor bar 4. In this case, the auxiliary tool 9 and the hook 7 are removed, and the tip of the scissor bar 4 is removed. In addition, if the core member 10 is attached via an auxiliary tool or the like (not shown), the core member 10 is inserted through the three loops of the pile yarn to form a loop-like bristle foot. Of course, it is not necessary to add a core material.

In the case of a cut veneer, the pile yarn 3 is squeezed into the scissor rod 4 and wound around the scissor rod 4 after the general purpose processes such as the weft insertion 5 and the squeezing yarn 6 are entangled and the reverse opening is performed. The pile yarn 3 may be cut.
