[0058] Preparation of cut laminated sheets

[0059] The method for preparing the cut laminated sheet of the present invention comprises the steps of (a) preparing a laminated sheet comprising a base sheet and a first protective sheet placed on one side of the base sheet; (b) laminating subjecting the sheet to a first shearing step to obtain a laminated sheet having raised portions at its side edges; and (c) subjecting the thus obtained laminated sheet to a second shearing step to remove the laminate The base sheet portion in the raised portion of the sheet so that only the first protective sheet portion remains in the raised portion of the laminated sheet.

[0060] In step (a) of the inventive method, a second protective sheet may be placed on the other side of the base sheet. In this case, as a result of the second shearing step, it is also possible in step (c) to remove the second protective sheet part in the raised part of the laminated sheet.

[0086] Example: Preparation of Cut Laminated Sheets by Using Combined Shear Assembly

[0087] The first and second shearing steps may be performed in the same shearing device assembly. Therefore, the second shearing step is performed sequentially after the completion of the first shearing step. This continuous process can be achieved by using a part of the stamping module used in the first shearing step in the second shearing step.

[0088] figure 1 A manufacturing process using a combination shear assembly is illustrated. For illustrative purposes, the figure 1 , put the first protective sheet and the second protective sheet on both sides of the base sheet.

[0089] refer to figure 1 (a), the laminated sheet comprising the base sheet 100 and the first protective sheet 210 (and optionally, the second protective sheet 220) placed on the base sheet is placed in the combination shearing device assembly 300 in.

[0090] The combination shearing device 300 may have a stamp...

Abstract

A cut-out laminated sheet can be effectively produced only with a two-step shearing process after a protective sheet is laminated on a base sheet. The cut-out laminated sheet can easily remove the protective sheet by using a projection unit, and thus increase the production efficiency. The same can be usefully utilized in the wide sheet processing field including a fragile sheet and a flexible sheet.

Description

[0001] This application is a divisional application of the patent application with the application number 201410120750.2, the application date is March 27, 2014, and the invention title is "cutting laminated sheet and its preparation method". technical field [0002] The present invention relates to a cut laminated sheet produced by cutting a laminated sheet having a base sheet and a protective sheet placed on the base sheet and a method for producing the same. Meanwhile, the present invention relates to a cut sheet from which a protective sheet has been removed. Background technique [0003] In order to prepare a functional base sheet having a specific shape suitable for electronic components and the like, protective sheets are laminated on both sides of the base sheet. In the prior art, such as Korean Patent Publication No. 10-1198919, the laminated sheet is then sheared. [0004] This commonly used protective sheet is generally removed before the base sheet is applied to...
