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 rubber member molding method for molding a rubber member having a belt shape by attaching rubber discharged from a die to a molding surface while relatively moving the die and the molding surface in a direction along the molding surface, the rubber member molding method includes setting, as an abutting position, a position where a first one of the die and the molding surface is moved in a direction of moving closer to a second one and abuts on the second one before start of molding, and setting, as a molding start position, a position where the first one is moved from the abutting position in a direction of moving away from the second one by a desired thickness of a rubber member at the start of molding.

An article may include a carcass or jacket, and at least one composite member arranged within the carcass or jacket for inhibiting longitudinal stretch of the article. The composite member may include a plurality of fibers arranged in a polymeric binder, the polymeric binder bonding the composite member to the carcass or jacket. The carcass or jacket may be formed substantially of rubber or thermoplastic elastomer. The plurality of fibers may include fibers formed substantially from at least one of S-glass, aramid and carbon fiber. The polymer binder may be formed substantially of a thermoplastic material or of a thermoset material. In manufacturing of the article, the carcass or jacket may be extruded to surround the composite member. The article may be a handrail or an elevator belt.

A method for producing endless abrasive articles (100) comprises: providing a mandrel coil (200), which comprises a first complete turn (BO.sub.A) formed of an endless mandrel belt (BO), feeding the endless mandrel belt (BO) to an input end (INO) of the mandrel coil (200) and unwinding the mandrel belt (B0) from an output end (OUT0) of the mandrel coil (200) so as to move the surface of the first complete turn (BO.sub.A) of the mandrel coil (200), forming a laminated sleeve (SLEEVE1) by feeding a first strip (S1) on the moving surface of the first complete turn (BO.sub.A) of the mandrel coil (200), and forming an endless abrasive article (100) by cutting the laminated sleeve (SLEEVE1).

A resin member has a longitudinal direction, includes a stretchable portion having an extending portion extending in a direction crossing the longitudinal direction, when the resin member is stretched in the longitudinal direction, an angle at which the extending portion extends changes, and the material of the stretchable portion contains cellulose fibers and a resin.

A manufacturing method of a molded article, including a first step of arranging a primary molded article made of a soft material in a molding die such that an outer peripheral surface of an exposed section of the primary molded article which is exposed to an outside without being embedded in a secondary molded article corresponds to an inner peripheral surface of the molding die, a second step of pressing and deforming an outer peripheral portion of the primary molded article arranged in the molding die by a pressing section so as to bring the outer peripheral surface of the exposed section into close contact with the inner peripheral surface of the molding die, and a third step of molding the secondary molded article by withdrawing the pressing section from inside the molding die while injecting resin to be the secondary molded article into the molding die.

The invention relates to a method and a device for demolding annular elastomeric molded parts from a mold core of an injection mold which has an inner mold core (1) and outer mold jaws and in which the molded parts (9) are produced parallel to one another in annular mold cavities (5) of the mold core (1). According to the invention, after removal of the outer mold jaws, the mold core (1), which contains the produced elastomeric molded parts (9) on the surface thereof, is set at such a high rotational speed about the longitudinal axis thereof that the internal diameter of the elastomeric molded parts (9) is increased because of centrifugal force to such an extent that the molded parts (9) are released from the mold cavities (5) and can be removed from the mold core (1) in the axial direction (10) while they are still rotating.

A method for forming a belt-like rubber sheet S by extruding rubber on a drum outer peripheral surface 3a by an extruder 2 includes: a front end forming step for forming a front end S1 having a wedge-shaped cross section; an intermediate part forming step for forming an intermediate part S2 having a desired thickness; and a rear end forming step for forming a rear end S3 having a wedge-shaped cross section by gradually decreasing an extrusion amount of the rubber to zero from a predetermined extrusion amount in a predetermined time, gradually decreasing the rotational speed of the drum outer peripheral surface 3a to zero from a predetermined rotational speed in the predetermined time, and gradually decreasing a distance from the drum outer peripheral surface 3a to a die 21 to an extrusion end distance from a predetermined distance in the predetermined time.

A band includes a tubular body configured to be worn on a user's body and a pocket supported by the tubular body, where the pocket defines a cavity and has an access opening providing access to the cavity, and where the pocket is configured to removably receive an electronic module in the cavity through the access opening. An input device is connected to the tubular body and has a port exposed to the cavity of the band, where the port is configured for removable connection to a connector of the electronic module when the electronic module is received in the cavity. The input device may include a button configured to receive user input and a wireless transmitter to transmit a signal to an external device based on the user input. The input device may also include a haptic feedback mechanism for communicating haptic signals to the user.

A band includes a tubular body defining a central passage, where the tubular body is configured to be worn on a user's body such that a portion of the user's body is received in the central passage, and a housing formed of a polymer material and connected to the tubular body. The housing defines a cavity and an access opening providing access to the cavity, and the housing is configured to removably receive an electronic module in the cavity through the access opening. The housing further includes a slot in communication with the cavity, with the slot configured to permit passage of moisture away from the housing. The sides of the tubular body may also define a slope that is from 0-0.75.
