摘要:
A re-treading method and an apparatus. An image of a zone of the tread material including its cut position is compared with a stored tread pattern image to detect a deviation amount. The tread material or the cut position are moved relative to each other by the deviation amount. The tread material is cut at the cut position after the relative movement. The tread material is wound on a base tire, and the leading and trailing edges of the tread material are united. The tread material or cut position may not be moved relative to each other if the deviation amount is within an allowable range.

The uneven wear produced in the tread side rib in the heavy duty pneumatic radial tire is prevented by arranging a peripheral fine groove on a particular region of the side face of the tread portion in a particular form.
摘要:
A main circumferential groove for a pneumatic tire having asymmetrical side walls. One of the side walls has three segments each inclined differently to a line normal to the tread surface. The angle of the inner segment is larger than that of an outer segment.

An ink supplying unit supplies a water-based ink having a predetermined water content set in advance. An ink form roller receives the water-based ink from the ink supplying unit. A plate cylinder is in contact with the ink form roller, and receives the water-based ink from the ink form roller. A water-content decreasing unit decreases the water content of the water-based ink on the ink form roller.
摘要:
An ink-transfer roller is brought into contact with an ink-source roller so that ink is transferred from the ink-source roller to the ink-transfer roller. The ink-transfer roller includes an ink-transfer member, an ink-transfer roller body, an elastic member, and a rotation axis. The elastic member is provided between the rotation axis and the ink-transfer roller body.
摘要:
An offset rotary printing machine which includes a first printing cylinder and a second printing cylinder in which printing is performed on a web at a nip between the pair of printing cylinders, the second printing cylinder contacting the first printing cylinder and being shifted downstream from the first printing cylinder. The printing machine includes an angle adjustment mechanism for adjusting an angle of a plane connecting center axes of the pair of printing cylinders which is inclined to a plane perpendicular to the moving direction of the web, and a controller for controlling the angle adjustment mechanism, based on parameters interrelating to a delamination occurrence probability that is caused as printing is performed by the downstream second printing cylinder.
摘要:
A pneumatic tire having a tread of a lug type pattern is disclosed. In this type of the tire, the tread rubber has a composite structure of a cap rubber and a base rubber having a heat build-up property lower than that of the cap rubber and arranged on at least a shoulder portion of the tread just beneath the cap rubber. The base rubber has a thickness that an average thickness just beneath the lug is larger than that just beneath the lug groove in a conical plane imaged by taking as a general line a normal line drawn from the tread end to the inner surface of the tire in the radial section inclusive of a rotational axis of the tire.
