U-shaped groove body for bookbinding, manufacturing method and application thereof

Abstract

The invention discloses a U-shaped groove body for bookbinding, a manufacturing method and an application thereof. The groove body comprises a U-groove main body made of a steel material; one upper end or two upper ends of the U-shaped groove main body are wrapped with falling-prevented adhesive tapes; one upper end of the U-groove main body is wrapped with a circle of the falling-prevented adhesive tape and then forms a unilateral wrapped forming body; and the two upper ends of the U-groove main body are both wrapped with a circle of the falling-prevented adhesive tape and then forms a bilateral wrapped forming body. The outer surface of the unilateral wrapped forming body or the bilateral wrapped forming body is wrapped with wrapping objects and then the U-shaped groove body for bookbinding is formed. A bookbinding envelope is formed by the combination of the U-shaped groove body for bookbinding and various covers, back covers and sealing ridges, and the bookbinding envelope is used to use a special bookbinding machine, so that text bookbinding is quickly finished, the primary demands, namely firmness and convenience, of bookbinding are effectively met, and bookbinding is more reliable, fast and convenient.

Description

technical field [0001] The invention relates to an office binding product, in particular to a U-shaped groove body for binding, a manufacturing method and an application thereof. Background technique [0002] The first requirement of office bookbinding is: bookbinding is reliable, there should be no page drop or pages are easy to drop during the text flipping process, this phenomenon means poor reliability; the second is work efficiency, cumbersome or step-by-step operation specifications will make work more efficient Greatly discounted; then there are requirements such as aesthetics. [0003] There are two main methods commonly used in office binding at present (all kinds of folders and file bags are not included in this statement), namely hole-punching binding and hot-melt adhesive binding. Punch binding, as the name suggests, is to punch the text pages first, and then use different forms of binding consumables to complete the binding of the text. Punch binding generally ...
