The device also includes a piezo actuator coupled to the upper part, a weight coupled to the lower part, a power supply configured to pass a current through the wire sample, an electronic balance beneath the weight, and a digital camera pointed at the tracking beads of the wire sample.

A method of evaluating fatigue in a hair fibre sample includes receiving fatigue testing data for the hair fibre sample for a plurality of loading cycles, in which the fatigue testing data comprises force or stress against displacement or strain data. The method also includes determining, for at least a subset of the loading cycles, a loading energy based on data from the fatigue testing data. The method also includes determining an indication of fatigue in the hair fibre sample based on the loading energy of the at least a subset of the loading cycles.

A method for creating a composite cable having at least one high-performance termination on at least one end. A high-performance termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a composite cable having a high-performance termination on at least one end. In most applications preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.

A flexibility testing apparatus for wire or cable. Two circular, rotatable gears are mounted to a frame, one gear being a drive gear and the other being a driven gear. The driven gear is coplanar with the drive gear and the drive gear teeth are enmeshed with the driven gear teeth. Two rods are connected to the mounting holes of the drive gear and the wire or cable is attached to the rods using barrel end clamps for flexing. The driven gear can be rotated at different speeds by an electric motor or a pneumatic driving device.

A device for performing a mechanical four-point bending test on a test piece and to a method for using one such device. The device comprises: a) structure for holding a first end of the test piece (27; 127; 28; 128) and structure for holding a second end of the test piece (30, 31); b) traction wire (25) and converting structure (16, 116) for converting a translational movement of said traction means into a rotational movement; c) conversion structure (26; 27; 126; 127) for converting said rotational movement into bending deformation of the test piece. Said conversion structure comprises at least one first Cardan joint (26; 126), connected to the structure for holding the first end of the test piece.

Provided is a method for predicting the remaining life of a hose and a method for diagnosing the deterioration level of a hose that can be easily performed without breaking the hose. The disclosure includes: a testing step of performing a hose bending test; and a predicting step of predicting the remaining life of a hose subject to prediction, wherein during the hose bending test, either a value of an external force required to displace a hose portion in a direction of the external force by a predetermined displacement amount, or a value of a displacement amount in a direction of the external force of the hose portion when the external force of a predetermined magnitude is exerted on the hose portion is measured, and the measured value is obtained as the test result.

An evaluating device of a flexural property includes a holder, a body disposed on the holder and capable of being moved along with a length of direction of the holder, a clamp coupled to the body to be rotated on the body and fixing a first side of the specimen to be evaluated, and a pressing part disposed over the clamp and pressing a second side of the specimen opposite to the first side and disposed upper than the first side of the specimen to bend the specimen, and an evaluation method of a flexural property of the bent specimen using the same.

A method and apparatus for measuring the cutting force on a single fiber. The method includes the steps of: providing a blade having an edge; providing a fiber mount for holding the single fiber; providing at least one sensor connected to the fiber mount; providing a fiber sleeve to contain a fiber within the fiber mount to simulate the location of the hair within the hair follicle; moving the blade toward the fiber and cutting the fiber; and measuring the cutting force on the fiber with the at least one sensor.

A preparation device prepares a sample of textile fibers, in particular cotton fibers, applicable to analysis and/or measuring apparatuses respectively for analyzing and/or measuring characteristics of the textile fibers forming the sample. The preparation device includes a comb body that can be coupled in a sliding manner along a rectilinear guide that faces a perforated plate against which to press a mass of textile fibers forming protuberances projecting from the holes of the perforated plate. The comb body is arranged to grip tufts of textile fibers from such protuberances. The preparation device also includes at least one brush that is mounted in a sliding manner along a rectilinear guide facing the perforated plate and that is arranged to brush the textile fibers forming the protuberances before the comb body grips the tufts.
