Disclosed is a cutting device and a method for cutting a continuous strip into tire components. The cutting device includes a knife for cutting the continuous strip along a cutting line in a working plane and a feeding assembly with a feeding member for feeding the continuous strip in the working plane to the knife in a feeding direction that intersects with the cutting line at a cutting angle. The feeding member and the knife are rotatable with respect to each other about a rotation axis perpendicular to the working plane for adjusting the cutting angle. The feeding assembly further includes an input member for receiving the continuous strip in an input direction into the cutting device and one or more guide members for guiding the continuous strip from the input member to the feeding member, wherein the input member is placed in line with or substantially in line with the rotation axis.

A method for manufacturing a belt-shaped cord member by cutting a rubber topped fabric produced by covering a topping rubber on an interdigitated fabric formed by interweaving many warp textile cords and few wefts to a predetermined width, comprising; an interdigitated fabric forming step of arranging a cord having conductivity for every predetermined number of the many warp textile cords which is then interwoven with the weft yarn, a rubber topped fabric producing step of topping rubber on the front and back surfaces of the interdigitated fabric, and a cutting step of cutting the produced rubber topped fabric by every predetermined number of the textile cords, wherein, in the cutting step, the rubber topped fabric is cut along the textile cord in which a cord having conductivity is arranged, after the position of the textile cords is specified by energizing the rubber topped fabric.

An apparatus for counting textile cords in a tire reinforcement belt by cutting the reinforcement belt into a plurality of belt units and successively measuring the number of textile cords in each belt unit is provided. The apparatus includes a feed roller having wound therearound a reinforcement belt on which textile cords are arranged along a longitudinal direction of the reinforcement belt; one or more take-up rollers configured to collect the reinforcement belt from the feed roller; a plurality of guide rollers interposed between the take-up rollers and configured to support a top surface or a bottom surface of the reinforcement belt; one or more light sources, each configured to emit a line of light onto a surface of the reinforcement belt that is passing around the guide rollers; and one or more image sensors configured to capture images reflected off the surface of the reinforcement belt.

To accurately cut a ply for a tire. It is a cutting device 1 for cutting a ply 10 for a tire in which a plurality of cords 12 parallelly arranged at fixed pitches are coated with an unvulcanized topping rubber 10. It has a pitch increasing means 2 for increasing the pitches of the cords 12 by pressing the ply 10 from a second surface 10b side to a first surface 10b side of the ply 10 so as to stretch the ply 10 toward the first surface 10a side; and a ply cutting means 3 disposed on the first surface 10a side of the ply 10, for cutting the stretched portion of the ply 10 along the cords 12.
