Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a papermaking fabric in which a guide protrusion is installed integrally with the fabric, and a papermaking apparatus using this papermaking fabric.

[Prior Art] Various paper manufacturing methods have been used in the technical field of paper manufacturing. For example, there are many paper manufacturing methods, such as the fourdrinier paper manufacturing method, which uses an endless woven fabric to make paper while supplying pulp slurry, and the combined paper manufacturing method, each of which can be applied to specific uses by taking advantage of its characteristics. has been done.

One of these methods is a paper manufacturing method using a circular mesh paper machine, which is often used to manufacture thick paper such as paperboard.

This cylinder paper machine injects paper stock onto a cylinder roll fitted with a circular mesh, dehydrates it to form a paper quality, and transfers this to felt etc. to make paper! I'm doing m.

However, in recent years, in order to increase the speed of paper production, attempts have been made to make paper using a circular mesh paper machine and an endless woven fabric instead of the circular mesh.

In other words, the injected paper stock is dehydrated to form a paper material.A cylinder roll with a circular net is used instead of the cylinder roll, and a GL-like fabric is stretched over a separately arranged inner roll to produce an endless fabric. Paper is made by rotating it in the same way as a cylinder paper machine.

Problems to be Solved by the Invention However, in the paper manufacturing method using such an endless fabric, there is a serious problem that the endless fabric may shrink or meander during use. .

The reason for this is that, according to research by the present inventors, when an endless 1a product is rotated, tension is applied to the warp threads, so they stretch in the warp direction.
The dimension in the weft direction becomes smaller. This is one of the causes of shrinkage. Furthermore, when an endless i#i fabric is rotated, the center of the fabric tends to advance further than both ends, causing shrinkage in the middle, wrinkles, and meandering.

A more serious problem is that when paper is made using a spiral woven fabric, a so-called curling phenomenon occurs in which the endless woven fabric is curled up from both ends in the width direction along with shrinkage, making it impossible to make paper.

This phenomenon occurs not only in papermaking using fourdrinier, but also in cases where, for example, in order to increase the papermaking speed mentioned above, a circular mesh paper machine is used and instead of the circular mesh, an endless fabric is stretched between the cylinder roll and the inner roll. When papermaking is carried out, as well as shrinkage, a so-called curling phenomenon occurs in which the endless fabric is curled up from both ends in the width direction, making it impossible to make paper. From the point of view of cylinder paper making, such a problem is a new problem that does not occur in conventional paper making equipment in which a cylinder roll is covered with a cylinder roll.

[Means and Effects for Solving the Problem] As a result of various studies, the inventor of the present invention has developed an inner roll having grooves near both ends, and a groove that fits into the inner roll near both ends in the width direction of the running surface.

In the present invention, guide protrusions that fit into the grooves provided in the inner roll are integrally formed and arranged on the running surface of the endless fabric for paper making, and are fitted into the grooves of the inner roll during use. To completely prevent the endless fabric from shrinking and meandering, a pressing part is installed on the outside of the protrusion of the endless fabric to make close contact with the shoulder provided on the outside of the groove of the inner roll. This eliminates the phenomenon in which the endless fabric curls up from both ends in the width direction.

In the present invention, the guide protrusions installed near both ends in the width direction of the running surface of the endless fabric are members that fit into grooves formed in the inner roll, and are formed integrally with the endless fabric. However, during use, a large amount of force is applied during use, so they must be joined together. In addition, this guide protrusion may be a continuous endless band or may be discontinuous.
The shape of the guide protrusion may be spherical, circular in cross section, elliptical, rectangular such as a triangular square, or a trapezoidal columnar body.Since the guide protrusion is subjected to a large force due to the width shrinkage of the endless fabric during running, the guide protrusion is If the wall on the center side in the width direction of the fabric is inclined diagonally downward, the force applied to the joint between the guide protrusion and the textile will be divided, so the force that tears the textile at the joint will be stronger than the vertical wall. It has the advantage of being smaller. As the guide protrusion, a protrusion having a series of horizontal portions extending on the roll surface can also be used. This horizontal portion is effective for forming a pressing portion to be described next.

In the present invention, a pressing part is formed on the outer side of the guide protrusion of the endless fabric, and is in close contact with the shoulder provided on the outside of the concave groove of the inner roll. It comes into close contact with the shoulder provided on the outside of the groove of the roll. In other words, this pressing portion tightens the shoulder portion provided on the outside of the groove of the inner roll. And since the width is not as wide as the papermaking part, this part itself hardly shrinks.Since the pressing part is in close contact with the shoulder part of the inner roll, the endless fabric is This means that the phenomenon of rolling up from both ends in the width direction does not occur at all.

This pressing part may be formed at both ends of the textile outside the guide protrusions installed near both ends in the width direction of the running surface of the endless textile, or the pressing parts formed at both ends of the textile may be Even better effects can be obtained by processing and integrating them.

A guide protrusion having a flat part is used, and this flat part and Il
If the width direction ends of the A-piece are joined together to form a pressing part, it becomes a very strong pressing part and has a great effect.

The guide protrusion used in the present invention is made of synthetic rubber,
It is preferable to use a material made of synthetic resin or the like.

In addition, any suitable means may be used to integrally combine with the fabric, but
Once settled, it is also effective in terms of strength.

The endless fabric of the present invention can be a single weave fabric or a multiple weave fabric.
Polyamide monofilament, polyamide monofilament, etc. are suitable as the thread constituting the woven fabric.

As can be understood from the above description, the endless papermaking fabric provided with guide protrusions of the present invention can be used not only as a one-liter papermaking fabric commonly called Fourdrinier or short net, but also as a papermaking fabric such as dry canvas. In addition, when used as an endless top fabric in papermaking, it prevents curling and forms good paper quality without meandering, similar to papermaking fabrics.

A cylinder paper making device using an endless paper making fabric provided with guide protrusions according to the present invention has grooves provided near both ends in the width direction of the endless paper making fabric described above, and shoulders provided on the outside of the grooves. The above-mentioned endless paper-making fabric is stretched between the inner roll and the cylinder roll, and the guide protrusions of the fabric are fitted into the grooves of these rolls. This is a paper making device in which a pressing part provided on the outside of the protrusion is brought into close contact with a shoulder part provided on the outside of the groove of the roll.

In addition, a papermaking device using an endless papermaking fabric provided with guide protrusions of the present invention has a plurality of pulp slurry discharge devices disposed above the papermaking surface of the endless papermaking fabric, and a plurality of pulp slurry discharge devices are arranged above the papermaking surface of the endless papermaking fabric, At least two inner rolls each having grooves near both ends in the width direction and shoulders on the outside of the grooves are disposed in front, and inner rolls are provided in the vicinity of both ends in the width direction of the running surface of the inner rolls.
