Abstract
A process and a splitter for splitting a tape of a uniaxially oriented material. The tape is passed in a process direction over a static splitting profile having a row of teeth, e.g., with a cutting edge extending in the process direction. The tape is split to form a material comprising a plurality of parallel strips interconnected by fibrils. The split material can for example be used for the production of high tensile ropes or laminates.
Claims17
A process of splitting a tape of a uniaxially oriented material, wherein the tape is passed in a process direction over a static splitting profile having a row of teeth splitting the passing tape into a material comprising a plurality of parallel strips interconnected by fibrils, the fibrils having a width which is smaller than a width of the strips.
A process for the production of a rope, wherein a tape of a uniaxially oriented material is split into a plurality of strips interconnected by fibrils, and wherein the strips are subsequently twisted to form the rope.
A uniaxially oriented material having a direction of uniaxial orientation and comprising a plurality of parallel strips with sides extending parallel to said direction of uniaxial orientation, the strips being interconnected by fibrils, the fibrils having a width which is smaller than a width of the strips, with one of said strips bordering one longitudinal side edge of the material and another one of said strips bordering an opposite longitudinal side edge of the material.
A splitter for splitting tapes of a uniaxially oriented material, the splitter comprising a splitter profile, a tape feeder for feeding tape to the splitter profile in a process direction, the splitter profile having a row of teeth which are triangular when viewed in the process direction, having a fixed position and orientation relative to the tape feeder.
