2. Description of the Related Art Wraps supplied to a carding machine are first subjected to an initial carding action and a dust removing action by a cylinder at a take-in roller portion, and then the same as the cylinder along the upper outer periphery of the cylinder. It is composed of a fibrous layer after undergoing a second carding action and dust removal action by a flat that is slowly moved in the direction, and finally a third carding action by a T-shaped bar with a combing member. Web was being delivered from cylinder to doffer.

[0003]

In the conventional carding machine, it is required to reduce the gauge between the flat cloths in order to improve the carding action received between the cylinder and the flat. You. However, when the gauge between the flat cloths is narrowed, the fiber layer passing between the cylinder and the flat is pressed against the surface of the cylinder, so that the cylinder on the doffer side between the cylinder and the T-shaped bar is not pressed. The carding action of the fiber layer received between them was insufficient.

In addition, when the fiber layer is pressed against the surface of the cylinder, the disadvantages described above are remarkable for cotton and synthetic fibers, particularly thin fibers and low-strength fibers. Each fiber was easy to wind around the cylinder surface, and transfer to the doffer was poor.
For this reason, it is not only impossible to spin the card sliver by the carding machine, but if spinning is possible, the gauge between the cylinder and the flat garment must be greatly expanded, As a result, nep and the like increased remarkably, and the parallelism became poor, so that it was not possible to prevent the deterioration of the quality of the card sliver.

The present invention has been made in view of these circumstances, and has a fiber layer moved toward a T-shaped bar floating on the surface side of a cylinder, and has a carding action on the fiber layer and a nep and dust removing action. The purpose of the present invention is to provide a carding machine capable of spinning both cotton and synthetic fibers having different fiber types and characteristics to a card sliver with one carding machine by installing this apparatus. It was done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a cylinder having a metallic wire 1a wound on a circumferential surface thereof. The cylinder 1 is provided with a take-in roller 2 having a metallic wire on the outer peripheral surface at the lower left side serving as a wrap supply side. A doffer 4 having an intermediate size between the small-diameter take-in roller 2 and the large-diameter cylinder 1 and provided with a metallic wire on the outer peripheral surface is provided on the lower right side of the side.

The take-in roller 2 is rotated in a direction opposite to the cylinder 1 at a circumferential speed of about half the circumferential speed of the cylinder 1 rotated in the direction of arrow P, and the doffer 4 is It is rotated in the opposite direction to cylinder 1 at a low circumferential speed.

A flat member 3 having a member 3a having a T-shaped cross section connected endlessly is provided in substantially the upper half of the cylinder 1. The flat 3 is moved at a very slow speed in the same direction as the cylinder 1. A flat cloth 3 has a T-shaped member 3a having a needle cloth 3b fixed to a surface facing the cylinder 1 and a take-in roller 2a.
And the metallic wire 1 of the cylinder 1
A carding action is again applied to the fiber layer from which the dust carried in step a has been removed to remove the nep, dust and short fibers.

A plurality of, for example, three T-shaped bars 6 each having a combing member 6a such as a metallic wire on the surface facing the cylinder 1 are provided near the doffer 4 between the flat 3 and the doffer 4. It is fixed with the gauge set to 1.

An opening roller 5 provided with a combing member 5a such as a metallic wire on the outer peripheral surface is provided near the T-shaped bar 6 between the flat 3 and the T-shaped bar 6. It is attached rotatably while maintaining The opening roller 5 is rotated at a low speed in a direction opposite to the cylinder 1.

An edge sheet (moat knife) 7 is provided between the opening roller 5 and the uppermost one of the plurality of T-shaped bars 6. The edge sheet 7 has a knife edge 7a formed at one end. The knife edge 7a is attached to the cylinder 1 and the opening roller 5 so as to be close to each other.

Between the opening roller 5 and the flat 3
Between the T-shaped bar 6 and the doffer 4, a front top sheet 8 and a front bottom sheet 9 which cover the outer surface of the cylinder 1 are provided to prevent the accompanying airflow generated by the rotation of the cylinder 1 from being disturbed. Is provided in proximity to the outer surface.

Next, the operation of the apparatus will be described. During operation of the carding machine, the wrap supplied to the carding machine is first subjected to carding and dust removal at the take-in roller 2 and then delivered to the cylinder 1.

The fiber layer held by the metallic wire 1a of the cylinder 1 and moved to the flat 3 side has a carding action again by the cloth 3b of the flat 3 moved in the same direction as the cylinder 1 at an extremely slow speed. The short fiber such as NEP and dust is further removed from the fiber layer.

The fiber layer which has been subjected to the carding operation again is subjected to a third carding operation by the opening roller 5 moved in the same direction as the cylinder 1 at a low speed, and the edge provided on the rear side of the opening roller 5 is provided. By the action of the sheet 7, dust and short fibers such as leaf dust are effectively removed, and the machine stand and the room are kept clean by a suction hood (not shown) provided at the portion.

In a carding machine, a high-quality card slide
Gauge between cylinder 1 and flat 3 to produce a bar
When the setting is narrow, the carding action in flat 3 is
Only ended fiber layer, on purpose made like held in the bottom portion of the metallic wire 1a of the cylinder 1. Opening ro
The roller 5 has a carding action and a rotating air current
With the help of, for example, the metallic wire 1a is made to float above the metallic wire 1a.

The fiber layer that has passed through the opening roller 5 is subjected to a final carding action at a plurality of T-shaped bars 6 provided on the rear side of the opening roller 5. At this time, since the fiber layer is floated above the metallic wire 1a of the cylinder 1 while undergoing the carding action by the opening roller 5, the fiber layers between the plurality of T-shaped bars 6 and the cylinder 1 which are subjected to the last carding action , An effective carding action is performed, and removal of the neps and improvement of the parallelism are measured.

The fiber layer moved to the doffer 4 side by the cylinder 1 is delivered to the doffer 4 side by the doffer 4 moved in the same direction as the cylinder 1 at a circumferential speed lower than that of the taker-in roller 2. In this case, since the fiber layer is floated on the surface side of the cylinder 1 and the engagement force with the metallic wire 1a is small, even when the force acting on the fiber layer is small, the fiber layer is moved from the cylinder 1 to the doffer 4 side. Can be delivered smoothly.

[0021]

According to the present invention, the following effects can be obtained.

In the carding machine according to the first aspect of the present invention, since a combing member is provided between the flat and the T-shaped bar and an opening roller which is rotated at a low speed is provided, a narrow gauge portion is required. The fiber layer that has passed through and is held on the bottom side of the metallic wire of the cylinder is floated on the upper side of the metallic wire by the carding action of the opening roller and the action of the rotating airflow, so that the engaging force with the cylinder is reduced. Therefore, fibers or et synthesis cotton spun, when switching to the spinning such fibers weak synthetic fibers and strength of especially fine denier, changing the working angle or the number of points Kushikezu member wound around the cylinder It overcomes the disadvantages of the prior art that had to be achieved and has the excellent practical effect that these fibers can be spun with a single carding machine.

Further, dust and short fibers separated by the opening roller are surely removed by an edge sheet having a knife edge formed at one end directed toward the opening roller. In addition, a T-shaped bar fixed on the back side of the opening roller and the edge sheet is attached to the front side of the cylinder.
