Abstract: An apparatus for cutting out an edge portion of a coating sheet wherein a plurality of cords arranged at substantially equal intervals and in parallel with each other and conveyed along a predetermined path are integrally coated with rubber or the like in such a manner that the cord portions are expanded, to a predetermined length from the most externally positioned cord portion of the coating sheet in transversal direction thereof is disclosed.

Abstract: A width of a selvage rubber portion extending in transversal direction of a coating sheet used for production of tire in which a plurality of cords arranged in substantially the equal interval and in parallel are integrally coated with rubber so that the cord portions are expanded, from the most externally positioned cord portion in said coating sheet, is precisely measured by transferring said coating sheet on a surface of a transferring member having a reflecting property different from that of the above described coating sheet in the longitudinal direction of said cord, emitting a light on a zone including at least the above described transferring member and the most externally positioned cord portion and detecting the light intensity distribution of the light reflected by the above described zone.

Abstract: A thickness measuring apparatus for non-metallic sheet-shaped bodies formed of rubber, plastic or the like which is simple in construction and small in size and can accurately measure the thickness of the non-metallic sheet-shaped body irrespective of high temperature change. It comprises a sheet position detecting mechanism including a light detector for receiving an image of the surface of the non-metallic sheet-shaped body and scanning the image and operative to detect the surface position of the sheet-shaped body on the basis of the output from the light detector. A roll position detecting mechanism detects that surface position of a metal roll which lies near the surface position of the sheet-shaped body to be detected. A processing mechanism calculates the thickness of the sheet-shaped body on the basis of the surface positions of the sheet-shaped body and the metal roll.

Abstract: A yarn in the form of a supply package in which the yarn is wound on a bobbin is continuously washed with an aqueous washing liquid by standing the yarn supply package upright in means for receiving the yarn package and an aqueous washing liquid, and continuously drawing off the yarn upward from the package while bringing the aqueous washing liquid into contact with the outer surface of the package. The contact of the outer surface of the package with the washing liquid is effected by immersing the package in the washing liquid bath or by flowing the washing liquid down over the outer surface of the package.
