Problems solved by technology

However, in this case, the following problem arises: when a fluororesin coating is used, the coating material gradually adheres to the unvulcanized tire as a foreign material
In this case, for example, the following problem arises: In the case where the sheet has a small thickness and is peeled off from unvulcanized rubber at once, the polyethylene sheet is broken due to the adhesive strength
As a result, clogging occurs in the canvas, and adhesion between the holding member and the green tire may gradually occur

Embodiment

[0061] Next, an exemplary tire holding device of an embodiment of the present invention will be described. The exemplary holding device is Figure 1A An example of a holding device 1 is shown. In these examples, the holding device 1 is made of FRP (Fiber Reinforced Plastic), an epoxy resin mixed with glass fibers. In the holding device 1, the tire holding portion 3—the area for receiving the unvulcanized tire 2—has an outer diameter R1 of 670 mm and an inner diameter R2 of 540 mm (see Figure 1B ).

[0062] Therefore, the tire holding portion 3 has a radial length R3 of 65 mm. The outer shape R4 of the base surface of the holding device 1 (see Figure 1A ) is 730mm. These dimensions are measured in a state where the covering material 4 is not installed.

[0063] These embodiments and the 3 conventional examples as shown in Table 1 were obtained by using holding means with these dimensions and materials and by changing the material of the covering material 4 and the tensi...

Abstract

An unvalcanized tire maintaining device for maintaining an unvalcanized tire comprises a tire maintaining portion, which is used as a carrying surface on which an unvalcanized tire is to be mounted; a covering material, which is used for covering at least a portion of the tire maintaining portion; and a covering material mounting region, in which the covering material is to be mounted. The covering material is a flexible sheet and is longer than the covering material mounting region.

Description

technical field [0001] The present invention relates to an unvulcanized tire holding device for transporting molded unvulcanized tires to vulcanization equipment. Background technique [0002] During tire manufacture, the green tire can stick to the holding device during storage and transport of the green tire. Such adhesion causes deformation of the tire and reduction in work efficiency. The problem of unvulcanized tires sticking to the holding device (referred to simply as "adhesion problem") occurs when the unvulcanized tires are stored on tray-shaped pallets made of plastic and stored in multi-storey automated warehouses. The case where the unvulcanized tire is transported from the molding process to the vulcanization process and the case where the unvulcanized tire is stored until the unvulcanized tire is put into a vulcanizer. [0003] Figures 7A-7C A conventional unvulcanized tire holding device is shown. Figure 7A is a side view of the holding device 100 on whic...
