Description

Technical Field

[0001] The invention relates to the field of wallpaper processing, and in particular to a slitting device and method for processing wide-width wallpaper. Background Art

[0002] Wide-format wallpaper is a type of wallpaper with a larger width. It is usually used to cover large areas of walls. It can effectively reduce seams and provide a more continuous and unified decorative effect. Compared with ordinary wallpaper, the width of wide-format wallpaper is usually more than 0.53 meters, and some can even reach 1 meter or more. The design and pattern of wide-format wallpaper are also more grand and eye-catching, suitable for large spaces or decoration needs that focus on visual effects. In the production of wallpaper, it is often necessary to cut the wallpaper.

[0003] At present, when the wallpaper is cut in the existing method, since the wallpaper is relatively soft, when the cutter contacts the wallpaper, the wallpaper is easily deformed and then shakes, and the stability is poor, which easily affects the processing accuracy and has poor applicability.
