It can be provided so as to be positioned at a predetermined drawer position.

[0020]

According to the carpet manufacturing apparatus of the first invention described above, in the pile yarn supplying section, pile yarns corresponding to two pile rows in the width direction of the carpet manufactured by the conveying means on both sides of the pile yarn supplying section are provided. The yarns are held by the yarn holding means and alternately arranged in a predetermined row for drawing in a horizontal row.

For example, as in the third aspect of the present invention, when the yarn holding means arranged at each pile planting position in the pile row in the width direction holds various types of pile yarns so that they can be pulled out, 2 rows 1 in the width direction of the carpet manufactured by both transporting means by means of physical or electrical selection means
Arbitrary pile yarns corresponding to each pile row of the set are alternately selected so as to be positioned at a predetermined drawing position. In this case, it is not necessary to preliminarily warp the pile yarn according to the handle and hold it by the yarn holding means.

Further, the conveying means on both sides are placed on a sheet-like base material corresponding to the carpet to be manufactured, and are intermittently fed. The adhesive is applied during the transportation of the sheet-shaped substrate, or is applied until it is supplied onto the conveying means.

Then, first, in a state where one of the draw-holding means is opposed to the front surface of the pile yarn supplying portion, the draw-holding means grips the end portion of the pile yarn held in a horizontal line at the draw-out position. Then, the pile yarns are pulled out to the front in the parallel state, and further, the pulling-out pile yarns are cut into a certain length according to the pile length by the cutting means which operates in response to the pulling-out.

When the cutting is completed, the one pull-out holding means holds the cut pile yarn by the driving of the moving means and the sheet-shaped base material at the bonding step position on the transfer means on one side. Move to the corresponding position. Further, the other drawer holding means interlocking with this is located at the front of the pile yarn supplying section.

Then, as described above, when one of the drawer holding means is moved to the bonding step position on the conveying means, the pile yarn held and transferred by the drawer holding means is bent and bonded to the guide. In this state, the pressing means is lowered to press down the central portion of the pile yarn to bend it through the bending and adhesive guide, and the bending portion is placed on the surface of the sheet-shaped substrate. Press and bond.

As a result, two rows of one are formed on the surface of the sheet-shaped substrate.
A set of pile rows is planted. Therefore, the conveying means intermittently feeds the sheet-shaped base material for every two rows of the pile row for each one of the adhesion operations.

Further, at this time, in the pile yarn supplying section in which the other pull-out holding means is located oppositely, the pile yarn corresponding to the pile row of the carpet manufactured by the conveying means on the other side is pulled out by the yarn holding means. The draw-out holding means, which are held in a horizontal row at a position, operate in the same manner as described above to grasp the end portion of the pile yarn and pull out each pile yarn for a predetermined length in a parallel state, By the action of the cutting means corresponding to the pulling action, the pulled-out pile yarn is cut into a certain length.

Then, again, both of the drawer holding means are moved in the opposite direction by the operation of the moving means, and one of the drawer holding means is positioned to face the pile yarn supplying section, and
The other drawer holding means is positioned corresponding to the sheet-shaped base material at the bonding step position on the conveying means on the other side.

In this way, the pile yarn held by the other drawer holding means is bent at the central portion through the bending and adhesive guide by the pressing action of the pressing means in the same manner as in the case of the one drawer holding means. Along with
The bent portion is pressed and adhered to the sheet-shaped base material on the conveying means. At the same time, the one pull-out holding means holds and pulls out the pile yarn in the same manner as described above, and the cutting means cuts the pile yarn into a certain length.

By repeating such operations in sequence,
On the two conveying means arranged on both sides of one pile yarn supplying section, the pile yarn cut into a certain length is bent at the central portion with respect to the surface of the sheet-like base material which is intermittently fed. Since the curved portion can be bonded and planted, a tile type carpet or the like can be efficiently manufactured.

Further, in the case of the carpet manufacturing apparatus of the second aspect of the invention, the pile yarn supplying unit corresponds to each of the pile rows of two rows in the carpet width direction to be produced, which are equally divided. The pile yarns to be arranged are aligned in a horizontal row in the order of each section and held at a predetermined drawing position. Further, in the conveying means provided in parallel with this, the sheet-shaped base material corresponding to the carpet to be manufactured is intermittently fed corresponding to the adhesive action. The adhesive is applied while the sheet-shaped base material is being fed, or is applied until it is supplied onto the conveying means.

Then, first, with the draw-holding means closest to the conveying means positioned in opposition to the pile yarn supplying section, the end of the pile yarn held by the yarn holding means is operated by the operation of the draw-holding means. While being grasped and pulled out in a state of being aligned in one horizontal line, the pile yarn pulled out by the cutting means operating in response to this pulling action is cut into a constant length corresponding to the pile length.

Next, the drawer holding means is moved together by the moving means to move the drawer holding means to the conveying means side, and the second drawer holding means from the conveying means side faces the pile yarn supplying section. Position it. Thus, as in the case of the first drawer holding means, the pile yarn held at the predetermined drawing position by the yarn holding means is
The end portion is grasped, pulled out, and cut into a certain length by a cutting means.

As described above, when the plurality of drawer holding means grips and pulls out the pile yarns and the cutting action associated with the pile yarns causes each of the drawer holding means to grasp the cut pile yarns, the moving means is moved. Thus, all the drawer holding means are positioned corresponding to the respective sections of the sheet-shaped substrate at the bonding step position on the conveying means.

Then, the pressing means is lowered to press down the central portion of the pile yarn which is gripped and transferred by each drawer holding means, is bent through the bending and adhesive guide, and the bending portion is The sheet-like base material is pressed and adhered to the surface thereof. As a result, two pile rows in the width direction are planted on the surface of the sheet-shaped substrate.

When the above-mentioned adhesion is completed, the pull-out holding means is moved together by the moving means to return to the initial state in which the first pull-out holding means is positioned to face the front surface of the pile yarn supplying section. At the same time, the transporting means transports the sheet-shaped base material for a distance corresponding to two pile rows.

In this way, the pile yarn having a relatively small width is obtained by repeating the above-mentioned grasping, pulling and cutting of the pile yarn by the respective drawer holding means, and the bending and adhering action of the pile yarn by the pressing means. Although it is a supply part, a fairly wide carpet can be easily manufactured.
