METHOD OF MANUFACTURING CORD INCLUDED RUBBER SHEET

摘要

A method for manufacturing a cord included rubber sheet has an arrangement step and a cutting step. In the arrangement step, a band-like material of a cord included rubber sheet is supplied to a processing table, and a portion to be cut is arranged onto a groove. In the cutting step, the band-like material is cut by pressing the pressure cutting die, and the cord included rubber sheet having a predetermined length is obtained. A leading end of the pressure cutting die enters the groove and a die surface of the pressure cutting die contacts with an opening edge of the groove, in the cutting step, and a cut surface of the cord is coated with the rubber of the band-like material in a process that the die surface comes into contact with the opening edge after the leading end contacts with the band-like material.

1. A method for manufacturing a cord included rubber sheet comprising:
an arrangement step of supplying a band-like material of a cord included rubber sheet to a processing table, and arranging a portion to be cut in the band-like material onto a groove which is formed in the processing table; and a cutting step of cutting the band-like material by moving a pressure cutting die having an angle of a leading end which is larger than an opening angle of the groove and is equal to or greater than a 85 degrees, relatively closer to the processing table, and pressing the pressure cutting die in a thickness direction of the band-like material, and obtaining the cord included rubber sheet having a predetermined length, wherein a leading end of the pressure cutting die is caused to enter the groove and a die surface of the pressure cutting die is brought into contact with an opening edge of the groove, in the cutting step, and a cut surface of the cord is coated with the rubber of the band-like material in a process that the die surface comes into contact with the opening edge after the leading end of the pressure cutting die is in contact with the band-like material.
