Abstract: The apparatus has an elongate and vertically running carrier (90) for pressure sensors (50), which precedes a group of levers (71 ). The cross section of this carrier (90) is arcuate, so that it has two flanks (93, 94 ). During the testing of a leg garment (80), this carrier (90) simulates the region of the shin. The apparatus has, furthermore, moldings or stays (88) which are carried by the levers and which simulate the rear face of the calf or of the thigh of a leg. The width of these stays corresponds to the width of the calf or of the thigh of a leg. The apparatus also comprises two longitudinally running groups (50) of pressure sensors, one of which is in each case assigned to outside of one of the flanks (93, 94) of the carrier (90). The leg garment (80) to be tested, in order to test it, is slipped over this apparatus in such a way that it lies on the outer faces both of the carrier (90) and of the stays and exerts pressure on the pressure sensors (51).

Abstract: A HSK spindle tension testing kit for measuring the force exerted by the drawbar assembly on the spindle on a CNC machine. The kit includes an upper frame member, a clevis, a pressure jack, a guide piece, a grip-housing, and a transfer rod. The guide piece is aligned over the grip-housing which is placed inside the front cavity on a HSK spindle. During operation, the drawbar assembly engages the grip housing. The transfer rod is threadingly connected at one end to the grip-housing, extends through the guide piece and connects to the shank on the upper frame member to hold the pieces together. During use, the pressure jack and clevis are then used to apply a pulling force on the transfer rod and to test the amount of force exerted by the drawbar assembly on the grip-housing.

Abstract: There is provided a method for testing the forces experienced by a wearer when donning a tubular article. The method includes securing one end of a tubular hosiery article to be tested to a support, inserting a tension tester head within the tubular body and measuring the force against the article surface as the tester head passes through the article. An apparatus for performing this method is also disclosed. The tester head has a geometric shape that may be advanced by withdrawing the head through the hosiery or the hosiery may be drawn past the tension head.

Abstract: A spindle tension testing kit designed to allow mill operators to quickly and easily determine the gripping or holding force of the coupler and drawbar assembly on a spindle against the tool holder used with a milling or other machine using this method of tool retention. In one embodiment, the kit includes a tool holder, an upper frame member, a transfer rod, a clevis member, and a modified pull stud, and a hydraulic piston. The upper frame member threadingly connects to the transfer rod that is longitudinally extended into the central bore formed in the tool holder. The frame member includes a central opening with a lower horizontal member designed to receive a clevis member. The clevis member is a U-shaped member disposed in an inverted, longitudinally aligned position over the lower horizontal member on the frame member so that its legs are adjacent to the top surface of the tool holder when assembled.

Abstract: A device for measuring a pulling-in force of a clamping system provided on a handling device of a machine tool. The device includes a support part having a support surface configured to contact a support surface provided on the handling device, and a pulling-in part movable relative to the support part, which is configured to be subjected to a pulling-in force acting in axial direction during operation of the clamping system. Also included is a deformation body disposed within an interior of the support part and firmly connected between the support part and the pulling-in part. The deformation body is subjected to deformation as a function of the pulling-in force applied to the pulling-in part. A measuring device is also included that is configured to mechanically sense the deformation of the deformation body, and configured to determine a magnitude of the pulling-in force based on a sensed degree of deformation of the deformation body.

Abstract: A method and apparatus for rapidly determining the cure state of an annular rubber or elastomeric article is provided. The article is placed so that an inner hole portion fits over separable parts of a test fixture, and tension is induced in a stepwise manner by moving the separable parts apart in discrete incremental steps. The tension is allowed to relax between the steps. By generating a force/deflection curve in this way, the user may optimize the cure state of the tested articles by controlling the cure time and temperature of a manufacturing process in response to the measured data.

Abstract: A predetermined force is applied to the waistband of a hosiery article to determine the waistband's maximum elongation, for the predetermined force and the band subsequently is relaxed to a preset dimension and the compression force exerted by the band is measured and recorded. The apparatus includes a stationary and a displaceable finger over which the waistband is stretched. A fluid cylinder moves the displaceable finger away from the stationary finger, producing the application of a predetermined force. Once the distance between fingers is measured, the cylinder moves the displaceable finger to position it a predetermined distance from the stationary finger and the compressive force applied by the waistband is measured and recorded. In order to insure that the displaceable finger is stopped with the exact predetermined distance between fingers, a calibration stop is first conducted to determine the distance the displaceable finger moves before it actually stops after receiving a stop signal.

Abstract: Three relatively movable fingers fit in a clamp at a preselected test diameter and pivot in response to a load transferred by the clamp. Load cells responds to the movement of the levers and the forces transmitted are displayed. In a preferred embodiment, the pivots are mounted to brackets which are fixed to the jaws of a chuck so as to be simultaneously movable to pre-selected spaced positions corresponding to the test diameter of the clamp.

Abstract: In a system for measuring the cross stretch along selected areas of a tubular portion of a hosiery article to determine whether the degree of stretch falls within selected parameters, a pair of arms having designated arcuate portions over which a selected area of the article to be tested is positioned. A fluid cylinder displaces a first arm relative to a second arm to stretch the selected area of the article and therefore apply a force to the second arm. When a prescribed force is reached, a control means, in response to a signal from a load cell coupled to the second arm, records the linear displacement of the first arm and reverses the operation of the fluid cylinder.

Abstract: A clamp tightness gauge determines the tightness of compressed sections having passages extending between the adjacent sections. The gauge has a frame to which a pair of spaced apart fingers are attached. The fingers have insertable opposed ends adapted to be inserted in a passage extending between adjacent sections. At least one (and preferably both) of the insertable ends is resilient. A wedge member is attached to an arm pivotably attached to the frame and has a tapered end slideably engaged with the insertable ends of the fingers for urging the fingers against the adjacent sections. The pivotable arm is in operative engagement with an externally threaded member moveably mounted on the frame. An indicator is connected to the wedge member for determining the displacement of its tapered end. Another indicator is connected to the pivotable arm for determining the forces exerted on the tapered end of the wedge member by the adjacent sections.

Abstract: An apparatus for measuring a radial force proportionally distributed over the circumference of a member having a circular cross section including a measuring means having a fixed part (2) and a movable part (3). The movable part (3) consists of a circular segment having an enclosed angle which lies between 90.degree. and 150.degree., the segment being radially movable in relation to the fixed part. The measuring means with movable and fixed parts are coupled through a load meter (6) rigidly connected at one end with the measuring means fixed part, and at the other end with the measuring means movable part. The load meter further comprises a bending bar (9) and means restraining movement of one end with respect to the other end except in one plane of the bar. The bending bar has a plurality of stretch strips.

Abstract: A pair of mandrels crossing at a right angle are moved into the center of an O-ring and then spread apart to stretch the O-ring around the mandrels to secure it and to form it into a twisted path. The mandrels are rotated to drive the O-ring through the twisted path so that the angular orientation of any given cross section of the O-ring changes as it advances around the path. An optical measurement apparatus senses cross section diameter of the O-ring at several locations. A support for one of the mandrels accommodates a load cell to measure the force developed by stretching the O-ring to provide a measure of O-ring elasticity.
