A method for manufacturing an endless belt includes: coating a depression that is formed between both belt longitudinal ends of surface rubber of a belt and to which an adhesion processing material is attached, with at least one layer of unvulcanized rubber sheet; and vulcanizing the unvulcanized rubber sheet to bond the unvulcanized rubber sheet to the surface rubber, in which A is less than B, where A is a belt longitudinal distance between a belt longitudinal edge of an interface of the unvulcanized rubber sheet and the adhesion processing material and a belt longitudinal edge of the depression, and B is a belt longitudinal distance between a belt longitudinal edge of an area to which the adhesion processing material is attached and the belt longitudinal edge of the depression.

A track for traction of a vehicle, such as an agricultural vehicle, an industrial vehicle (e.g., a construction vehicle), a military vehicle, or another off-road vehicle, is provided. The track comprises a ground-engaging outer surface for engaging the ground and a plurality of traction projections projecting from the ground-engaging outer surface and distributed in a longitudinal direction of the track. The traction projections may be designed to enhance their resistance to deterioration during use. For example, a blowout resistance of each traction projection may be enhanced to prevent or at least reduce a potential for blowout of the traction projection under repeated loads which may induce heat buildup within it. Also, a wear resistance of the traction projection may be enhanced such that the traction projection wears less rapidly. A system for protecting a track against potential occurrence of blowout is also provided.

A belt and a method for manufacturing a belt is provided. The belt includes a plurality of lengthwise-extending tension members and a jacket. The jacket substantially retains the plurality of tension members. The jacket has a first side region, a second side region, and a center region between the first and second side regions. The first and second side regions of the jacket are more fire retardant than the center region of the jacket.

An automatic canvas wrapping machine including a canvas conveying device, a yarn core mounting device, a canvas wrapping device, and a cutting device is described herein. The canvas conveying device conveys a rubberized canvas for wrapping a yarn core. The yarn core mounting device is disposed in a conveying direction of the canvas conveying device, and the yarn core is mounted in the yarn core mounting device and attached to the rubberized canvas conveyed by the canvas conveying device. The canvas wrapping device is disposed on one side of the yarn core mounting device and presses the rubberized canvas reciprocatingly along a direction vertical to the conveying direction, so as to tightly attach the rubberized canvas to the yarn core. The cutting device is disposed at an upper part of the canvas conveying device and cuts the rubberized canvas after the canvas wrapping device completes canvas wrapping.
