Problems solved by technology

[0008] In addition, due to the deviation of the separation angle, the deviation from the desired bonding position will cause poor bonding, and if the slack on the front side and the back side of the device deviates, oblique bending will occur.

Abstract

The invention relates to a sheet cementing device, a post treatment device, a sheet cementing method and an image forming device provided with the sheet cementing device. A sheet holding drum holds a second sheet cemented with a first sheet by means of cementation and laminated releases paper both of which can be output in a reeling state, and is provided with a torsion limiter which endows the sheet holding drum with torsion reverse to releases paper conveying direction. The sheet cementing method can obliquely convey the first sheet and the second sheet. Cementing position deviation is not in existence when the two sheets are cemented at an oblique position. The invention also provides the sheet cementing device and the image forming device, which can prevent cemented media from being wrinkled and obliquely bent and prevent air bubbles from being mixed.

Description

technical field [0001] The present invention relates to a sheet bonding device for bonding sheets, a post-processing device, a sheet bonding method, and an image forming apparatus provided with such a sheet bonding device. Background technique [0002] At present, there are various structures for forming sheets between adhesive sheets. For example, an image is formed on one side of a transparent sheet by an electrophotographic image forming device, and the transparent sheet and white paper are sandwiched between the transparent sheet and the white paper. image, bonded to form an image-recording sheet. [0003] Using an electrophotographic image forming apparatus to form a glossy, textured image close to photographic quality is a very effective technical means. In the past, as a bonding means for obtaining the image recording sheet, for example, Adhesives such as spray paste are sprayed onto the image side of the transparent sheet to bond the transparent sheet and white pape...
