AI Technical Summary
Existing fabric wrapping methods make it difficult to effectively control the amount of adhesive on the fabric, resulting in unstable bonding strength and easy detachment of the fabric wrapping lap.
The system adopts a banded reverse wrapping structure, with the connecting layer located at the top of the wrapping belt. The outer canvas has a gap near the connecting layer, exposing part of the top adhesive layer. Adhesive bonding is used to enhance the bonding strength, and a connecting layer is added during the vulcanization process to further enhance the bonding effect.
It increased the bonding strength by more than 15%, prevented the fabric overlap from coming undone, and enhanced the stability of the bonding layer.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric wrapping tape, specifically to a multi-link reverse-wrapping fabric wrapping tape. Background Technology
[0002] The current method of covering the fabric is full wrapping (positive wrapping), which means that after the belt is coated with glue, the entire belt is wrapped during the covering process, so that the canvas and the connecting layer are bonded together. The strength of the bond is directly affected by the amount of glue on the fabric, and it is difficult to control the amount of glue on the fabric. Summary of the Invention
[0003] This utility model aims to provide a combined reverse-wrapping fabric belt, the specific solution of which is as follows:
[0004] A type of interlocking reverse-wrapping fabric belt includes a connecting layer and two or more wrapping fabric belts. The connecting layer is located on top of the wrapping fabric belts and connects the wrapping fabric belts. Each wrapping fabric belt includes an inner belt body and an outer covering canvas. The inner belt body includes a top adhesive layer. The outer canvas has a gap near the connecting layer, and part of the top adhesive layer is exposed through the gap.
[0005] The gap is 1-3mm.
[0006] The connecting layer includes a wide-angle layer and a curtain fabric layer, and the curtain fabric layer is provided with an adhesive layer. The wide-angle layer and the curtain fabric layer are connected by adhesive.
[0007] The outer canvas includes an outer canvas layer and an inner canvas layer.
[0008] The internal belt comprises, in sequence, a top adhesive layer, a cord layer, a thin adhesive layer (made of the same material as the bottom adhesive), and a bottom adhesive layer.
[0009] This utility model discloses a type of inverted-coverage fabric belt with a 1-3mm slit at the top of the belt to expose the top adhesive and directly bond it to the adhesive on the fabric surface of the connecting layer, thereby improving the bonding strength of the connecting layer (actual testing showed that the bonding strength can be increased by more than 15%). Furthermore, the fabric lap is not located at the bottom of the belt, eliminating the possibility of the bottom fabric lap coming undone during use (i.e., the inverted-coverage method involves the outer canvas wrapping around the inner belt body, but a gap exists near the connecting layer, i.e., a gap is left at the top of the inner belt body). Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of a combined reverse-wrapping fabric belt according to the present invention;
[0011] The labels are as follows: 1. Connecting layer; 11. Wide-angle layer; 12. Curtain fabric layer; 2. Covering tape; 21. Outer canvas layer; 22. Inner canvas layer; 23. Top adhesive layer; 24. Cord layer; 25. Thin leather adhesive layer; 26. Bottom adhesive layer; 27. Gap. Detailed Implementation
[0012] The following is combined Figure 1 Further explanation:
[0013] A type of interlocking reverse-wrapped fabric belt includes a connecting layer 1 and two or more wrapping fabric belts 2. The connecting layer 1 is located on top of the wrapping fabric belts 2 and connects the wrapping fabric belts 2. The wrapping fabric belt 2 includes an inner belt body and an outer covering canvas. The inner belt body includes a top adhesive layer 23. The outer canvas has a gap 27 near the connecting layer 1 and is not fully covered. Part of the top adhesive layer 23 is exposed through the gap 27.
[0014] The gap 27 is 1-3mm.
[0015] The connecting layer 1 includes a wide-angle layer 11 and a curtain fabric layer 12, and the curtain fabric layer 12 is provided with an adhesive layer. The wide-angle layer 11 and the curtain fabric layer 12 are connected by adhesive.
[0016] The outer canvas includes an outer canvas layer 21 and an inner canvas layer 22.
[0017] The internal belt includes a top adhesive layer 23, a cord layer 24, a thin adhesive layer 25 (made of the same material as the bottom adhesive), and a bottom adhesive layer 26 arranged sequentially.
[0018] This utility model uses a base adhesive layer 26 + a thin adhesive layer 25 + a cord layer 24 + a top adhesive layer 23 for the fabric covering, followed by fabric wrapping: first an inner layer, then an outer layer (outer canvas layer 21 and inner canvas layer 22, with a gap 27 left at the top during the outer wrapping). Finally, a connecting layer is added during the vulcanization process (i.e., the wide-angle fabric 11 is bonded to the inner curtain layer 12 with adhesive). In this utility model, the top adhesive layer 24 is directly bonded to the curtain fabric layer 12, i.e., using an adhesive and fabric bonding method, which increases the bonding strength by more than 15% compared to existing solutions.
[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
