Embodiment Construction

[0011] Such as figure 1 and figure 2 As shown, in a preferred embodiment of the present invention, the processing method of this extremely fragile processed paper of the present invention includes the step of performing dotted line knife cutting or punching on the paper, wherein the paper has a cut edge As for the side thread part, the paper includes more than two side-by-side narrow-width slitting paper strips, wherein, firstly, between the dotted line incision 2 or the hole-shaped incision 3, the uncut or punched paper with a width of 2mm to 20mm is reserved. The paper part 4 of the hole; secondly, widen the width of the trimmed edge 1 of the paper, the width of the trimmed edge 1 is 1 mm to 20 mm, and make the widened trimmed edge 1 not be cut or punched; finally, For the widened side wire 1 that is not cut or punched, it is cut off by the cutting process behind the cutting or punching process.

Abstract

The tear-off paper processing method includes dash cutting or perforating step. During the dash cutting or perforating step, two intact fringes of at least 1 mm width are retained and several intact narrow bands of at least 2 mm width are retained. The intact parts are cut down in the last cutting step. The said processing method makes the paper capable of bearing the processing tension before being processed into tear-off paper product.

Description

Technical field: [0001] The invention relates to a paper processing method, in particular to a processing method for processing easily broken paper. Background technique: [0002] In the prior art, the final products of some paper are required to be easily broken, such as folding paper for electrocardiogram, carbonless folding paper, paper for queuing machines, etc., all of which belong to this type of product. The characteristic of these papers is that they are easy to break along the folds. Before the paper is rolled up, there is a dotted line knife cutting or punching process, and this process makes the processed paper have only a very small tensile strength. . Therefore, this kind of product is prone to breakage during processing, which directly leads to low productivity and reduced yield, which eventually leads to increased production costs. In order to minimize the loss of such products during processing and improve efficiency, it is usually solved by reducing the co...
