Problems solved by technology

This makes the center of the fabric bulge when it is drawn to the paper machine, making seaming more difficult and causing the edges of the fabric or belt 16 and guide 10 to sag 18 and 20
[0021] The disadvantage of this type of guide is that the load is always concentrated in the area down the center of the guide
When pulling the fabric through the machine, this shortcoming causes the center of the guide and the fabric attached to it to lead ahead of the edges and create waves in the center, making it more difficult to sew when installed and to guide the fabric through its course
This shortcoming often causes the edges of the fabric to droop as it is pulled through the fabric travel

Embodiment Construction

[0036] first, figure 2 A side view of the press section of a paper machine is shown. image 3 A side view of a typical paper machine dryer section is shown. The path of the fabric used for these parts is shown in the figure. The present invention is used to load fabrics into such paper machines.

[0037] The multi-ply fabric loading harness of the present invention is a rope harness attached to a guide to assist in loading the fabric into the paper machine. The harness is self-balancing and comprises at least two layers, wherein each layer is made from a continuous length of rope. The guide is supported in its transverse direction by rigid elements. For example, metal strips can be inserted across the entire width of the guide. The first layer (or stage) of cord is formed by securing the cord to the hole in one edge of the guide, passing the cord loosely in loops through a series of holes in the transverse direction of the guide, and The end is fixed to the hole in the o...

Abstract

A multi-layer fabric loading fixture for loading fabric onto a paper machine. The loading fixture includes a first portion (400) with a rigid support member (410) and a plurality of spaced holes (420) across its width, the first portion being connected to an end of the fabric in the cross-machine direction. The first layer (430) is formed of cords which are sequentially threaded through the holes to form a self-adjusting loop. The second rope is sequentially threaded through the loops of the first layer to form the self-adjusting loops of the second layer (440). Pull rings (450) gather the loops of the second layer and are used to draw the fabric to the paper machine.

Description

technical field [0001] The present invention relates to papermaking technology. More particularly, the present invention relates to a guide apparatus for drawing a seamable papermaking fabric to a papermaking machine. Background technique [0002] During papermaking, a web of cellulose fibers is formed in the forming section of a paper machine by depositing a fiber slurry, which is an aqueous dispersion of cellulose fibers, onto a moving forming fabric. Most of the water in the slurry is drained through the forming fabric, while the cellulosic web remains on the surface of the forming fabric. [0003] From the forming section, the newly formed cellulose web enters the press section, which consists of a series of press nips. A web of cellulosic fibers is supported by a press fabric, or typically between two such press fabrics, and passed through the press nip. In the press nip, the cellulosic web is subjected to compressive forces that force water out of it and cause the c...
