Problems solved by technology

The disadvantage of this method of winding up the reel of the paper machine is that when the small paper ear is widened from the operating side to the driving side, the paper layer on the operating side is relatively thick, so the tension in the diameter direction of the winding roll is inconsistent, resulting in deadlock. Only when the winding reaches a certain line length, the thickness difference between the transmission side and the operation side is no longer obvious, and the dead lines gradually disappear after the tension on the winding roller is stable.
Therefore, the traditional winding mode is easy to cause bottoming dead lines or paper damage, resulting in a large amount of paper damage

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] The present invention adopts the method that the paper strip is rolled up from the middle part in the take-up part of the paper machine, and then fully widened. In the accompanying drawings, 1 is a winding roll, 2 is a paper ear, and 3 is a hollow roll. One side of the winding roll 1 is the transmission side, and the other side is the paper ear operation side. When the paper machine is wound, the paper is smoothly wound by the mutual rotation of the winding roll 1 and the hollow roll 3.

[0015] When winding the threading paper, firstly thread the paper ear 2 on the paper ear operation side of the paper roll 1, see Figure a; after the paper ear 2 is successfully drawn, lead it to the middle position of the paper roll 1, The entire roll web is the paper web after coiling, see attached drawing b; roll up after the paper ear stays in the middle position, see attached ...

Abstract

The invention relates to a method for coiling at the middle, used in paper coiler, wherein it comprises: first, guiding the paper ear at the coiling roller; then guiding the paper ear into the middle of roller; then widening the middle paper ear to two sides of coiling roller. The invention can be used to produce paper to realize coiling at middle and widening. The invention can improve the paper quality, without affecting guiding time.

Description

1. Technical field [0001] The invention belongs to the field of papermaking, in particular to an intermediate winding method for a paper machine coiling section applied in the papermaking technology. 2. Technical background [0002] In the current papermaking industry, when the paper machine is reeling, one side of the winding roll is the transmission side, and the other side is the paper lug operation side. The transmission side drives the paper roll to rotate, and the paper is smoothly wound by the mutual rotation of the paper roll and the hollow roll. [0003] The commonly used winding method in the traditional take-up section is to wind up from the side of the paper web through the small paper ear, and then unwind or roll up after the full width of the paper. The disadvantage of this method of winding up the reel of the paper machine is that when the small paper ear is widened from the operating side to the driving side, the paper layer on the operating side is relative...
