An extruded strap is produced of a material containing renewable raw materials and the ends of which strap can be welded together. A method for producing the extruded strap and a method for strapping an article using the extruded strap are also provided.

An endless flat belt includes an inner rubber layer 1, a cord core 11 buried in the inner rubber layer 1 and spirally wound at a predetermined pitch in a width direction of the belt, and a reinforcement fabric 2 stuck to the inner rubber layer 1. The cord core comprises polyamide fiber. Opposite ends of the reinforcement fabric 2 are connected with each other into an endless form by adhesion or sewing. A surface rubber layer 3 is stuck to a surface of the reinforcement fabric 2 which is opposite a surface thereof stuck to the inner rubber layer 1.

Provided is a method for producing a rubber crawler capable of suppressing deformation of tension members which probably occurs during the manufacture. The method for producing a rubber crawler 1 comprises: obtaining rubber protrusions 4, 5 having half-vulcanized surfaces 4a, 5a by vulcanizing an unvulcanized rubber RR while keeping a half-vulcanized state; obtaining a main body 2 having half-vulcanized surfaces 2c, 2d by vulcanizing an unvulcanized rubber RR with tension members 3 embedded therein while keeping a half-vulcanized state; and arranging the rubber protrusions 4, 5 on the main body 2, and then integrating the rubber protrusions 4, 5 and the main body 2 by vulcanizing the same.

A method of making an elevator load bearing member includes unidirectional weaving a plurality of load bearing fibers including at least a first material and a second material. A melting point of the first material is higher than a melting point of the second material. The method includes bonding the load bearing fibers together by at least partially melting at least some of the second material and coating the plurality of load bearing fibers.

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.
