CZ301197B6 - Method of making segmented sheet, particularly map or plan - Google Patents

Abstract

The present invention relates to a method for making a segment sheet, especially a maps or plan wherein the segments are placed in vertical and horizontal rows and separated by narrow gaps. The invention is characterized that on the bottom (1) of sheet on which is printed a picture or a text are made narrow horizontal (5) or vertical (6) notches, which separate segments (4), displacing at least one joint in horizontal (5) or vertical (5) notches, which joins adjacent segments (4), whereas by making horizontal (5) and vertical (6) notches, sheet (1) is covered with layers of flexible transparent material, which are connected together. Horizontal (5) and vertical (6) notches are made by a tool, which comprises cutting modules (9), each of which comprises two joined cutting blades (10, 11) and two shearing knifes (12, 13) wherein said shearing knifes (12, 13) fit close to front surfaces of the cutting blades (10, 11).

Description

A method of creating a segmented sheet, in particular a map or plan

Technical field

The invention relates to a method of forming a segmented sheet, in particular a map or plan, coated on both sides with elastic, translucent layers, the segments being spaced in vertical and horizontal rows and separated by narrow gaps.

BACKGROUND OF THE INVENTION

Maps, city plans, tourist guides, guides and similar documents that are frequently used are at risk of damage, especially in field conditions, such as during hiking trips, which reduce their readability.

Moreover, the paper-based documents mentioned are uncomfortable in use, since they cause difficulty in unfolding, especially when used in confined spaces, for example in vehicle cabins. In order to increase durability, the documents are coated with a layer of elastic, translucent material. The maps, plans or documents coated in this way are divided into sections and bent along their edges. Coating with these elastic layers, however, does not facilitate the use of maps, plans or other documents as the elastic material layer tends to return to the shape obtained during the bending process. In addition, forcibly bending the elastic layer in the opposite direction to that initially obtained causes it to wear quickly and break along the fold line.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a method of forming a segmented sheet, in particular a map, plan and the like, coated on both sides with elastic, translucent layers, wherein the segments are arranged in horizontal and vertical rows.

A method of forming a segmented sheet, in particular a map or plan, coated on both sides with elastic, translucent layers, the segments being spaced in vertical and horizontal rows and separated by narrow gaps according to the invention, consists in that in the base of the sheet to which the image is applied or text, narrow horizontal and vertical cuts are made separating the segments and at least one connecting link is left in the horizontal and vertical cuts, connecting adjacent segments and, after horizontal and vertical cuts, the sheet is covered with elastic, translucent layers on both sides The horizontal and vertical cut-outs are formed by means of a tool consisting of cutting modules, each equipped with two interconnected cutting blades and two cutting blades adjacent to the front surfaces of the cutting blades.

The layers of elastic, translucent material are joined to each other along the entire length of the horizontal cut-outs and vertical cut-outs, or they are joined together in a spot-like manner.

The segmented sheet produced by the method of the invention ensures a permanent and elastic connection of all segments and allows them to rotate 360 ° without permanently deforming the elastic layers. In the case of a point-to-point connection of elastic layers overlapping the sheet on both sides, an air bubble develops between the point joints, which additionally increases the elasticity of the joint. The method according to the invention allows the joining of sheet segments in one or more rows, both vertical and horizontal.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 schematically shows a plan view of a segmented sheet coated with elastic layers on both sides; and FIG. 2 is a side view of a cutting module for forming horizontal and vertical cut-outs in the base of the sheet.

DETAILED DESCRIPTION OF THE INVENTION 10

A method of forming a segmented sheet, in particular a map or plan, coated on both sides with elastic, translucent layers, consists in providing narrow horizontal cut-outs 5 and vertical cut-outs 6 separating from each other in the base of the sheet 1 to which the image or text is applied. At the same time, at least one connecting link connecting adjacent segments 4 is left in the horizontal slots 5 and the vertical slots 6. After the horizontal slits 5 and the vertical slots 6 have been made, the sheet I is coated on both sides with layers of elastic, translucent material. The layers are then joined together. The horizontal cut-outs 5 and vertical cut-outs 6 are formed by means of a tool consisting of cutting modules 9, each equipped with two cutting blades 10, 11 connected to one another. and two cutting knives 12 and 13 adjacent the front surfaces of the cutting knives

10, The layers of elastic, translucent material are bonded to one another along the entire length of the horizontal slots 5 and the vertical slots 6, or may be spot-joined in these slits.

Experience has shown that the map or plan, as well as other documents produced in the form of a segmented sheet by the method according to the invention, are characterized by high utility properties. In addition, the segmental sheet is durable and does not change its external appearance and therefore does not change its readability even after prolonged use.
