Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic leather sheet having an interlining coated with a synthetic resin and a method of softening wrinkles on other sheets and a wrinkling softening device thereof.

2. Description of the Related Art A conventional wrinkle softening device, as disclosed in JP-A-53-96301, has kneading rolls for sandwiching a synthetic resin sheet from both sides in three upper and lower stages. Rubbing was done by bringing it into and out of contact with an intermediate one.

Further, as a detailed disclosure of the same invention as this JP-A-53-96301, there is JP-A-58-13784,
Japanese Utility Model Laid-Open No. 60-20595 discloses that only the upper half of the rubbing mechanism of the main part is limited. These are characterized in that a kneading roll moves up and down, and a slackened synthetic leather sheet is compressed in the meantime, that is, the same operation as grasping and kneading with both hands is performed. In contrast to these, Japanese Patent Laid-Open No. 58-1973
Japanese Patent Laid-Open No. 80 discloses an alternating rubbing roll supported by a horizontal shaft crank and an up-and-down rubbing roll with respect to a sheet which is moved laterally, and tries to perform a rubbing action in a separated state.

In the conventional configuration, the approaching widths of the upper and lower rubbing rolls are the same, the positions for sandwiching the sheets are the same in the upper and lower sides, the rubbing processing is not performed uniformly, and the upper and lower rolls have the same width. The kneading pressures were remarkably different from each other, resulting in non-uniform pressure, resulting in uneven kneading. In addition, rubbing in the dyeing tank could not be performed.

Means for Solving the Problem A base is supported by a frame outside both side edges of a synthetic leather sheet stretched vertically, and a bearing body is supported by being axially supported by the tips of a pair of parallel link arms vertically. The kneading rolls, which are arranged and whose opposing surfaces expand and contract with the rotary cranks supported by their respective bearings, and which sandwich the sheet in a corrugated manner from both sides, are passed over, and the swingable kneading rolls are vertically arranged. A plurality of stages described above are arranged at required intervals, and a fixed position kneading roll is provided below both ends of which a shaft is mounted on a rotary crank of a bearing body provided on the frame. It is characterized by descending two or more stages of rubbing rolls to give each rubbing roll a slack proportional to the respective working width, and locating this slack between the rubbing rolls to perform wrinkle soft processing. Wrinkled and flexible processing of synthetic leather sheets On the way.

Further, also below the fixed position kneading rolls, the same kneading rolls as the above two or more stages are arranged at required intervals,
The upper two or more kneading rolls are lowered, the lower two or more kneading rolls are raised, and the synthetic leather sheet is loosened in proportion to the different descending width or rising width of each rubbing roll. No, and this slack portion may be located between the respective kneading rolls, and the wrinkle softening process may be performed by the pressure contact rocking action of the respective kneading rolls.

Further, as a device for carrying out the above method, a supporting roll is axially supported with a required gap vertically, and a synthetic leather sheet is stretched on the supporting roll, and outside of both side edges of the synthetic leather sheet. The base end is supported by the frame, and the bearing body is arranged by axially supporting the tip ends of a pair of parallel link arms that are vertically arranged.
A rotary crank supported by each of the bearing bodies is provided with a rubbing roll whose nipping surface is bent in a wavy manner in two or more stages above and below,
A fixed position rubbing roll is provided by arranging them at a required interval, and both ends of which are fixedly mounted on a rotary crank of a bearing body provided on a frame, and parallel links of the above-mentioned two or more stages of rubbing rolls. A driven rope having a length corresponding to each ascending / descending distance is connected to the arm at one end of the interlocking rod and at a position different in the ascending / descending rotation distance, and the other end of the interlocking rod is associated with the driving rod associated with the operating rod. And suspend the driven rope up and down, sandwich the synthetic leather sheet at the highest position of the respective kneading rolls, and lower each to lower the synthetic leather sheet between the corresponding upper and lower kneading rolls. This is an apparatus for slackening to intervene, and slackening is performed by squeezing and oscillating this.

Action Since the wrinkle-softening method and device of the present invention are configured as described above, the kneading rolls having two or more ascending / descending distances ascend / descend with respect to the fixed position kneading rolls to make the slack width different and perform the kneading action. In addition, if the slack width is wide, it will be a large wrinkle, and if the slack width is narrow, it will be a small wrinkle.By applying a rubbing pressure to the fixed-position rubbing roll from above in multiple stages, and different distances, various wrinkles can be created. Therefore, it is possible to perform sufficient wrinkling and soft processing. In addition, by adding a slack width and a kneading pressure from the bottom to the fixed position kneading roll in multiple stages and with different distances, it becomes more diverse,
It is capable of sufficient wrinkling and flexible processing.
