DEVICE FOR MECHANICAL TESTS OF SEWING MATERIALS AND CONNECTIONS Russian patent published in 2008 - IPC G01N3/08 

FIELD: physics, measurement.

SUBSTANCE: stated invention is related to light industry, in particular, to devices for mechanical tests of sewing materials and connections of clothes parts (thread, welded, glued and other seams and stitches). Objective of suggested device is increase of clothes and other garments quality by preliminary assessment of mechanical characteristics of sewing materials and connections of parts from action of pluriaxial deformations. For that purpose device includes clamping facility for fixation of tested sample in the form of circuit of several open clamps, which are installed, for instance, at mutually perpendicular axes, coaxially to clamping facility stem is installed with working actuator in the form of puncheon that is kinematically connected with mechanism of loading and measurement of deforming action, which includes connecting rod, double-arm lever with electric strain sensor and drive with connection unit. Accessory that contains elastic elements with electric strain sensors is used for measurement of pluriaxial deformation. Elastic elements are connected with mentioned clamps. All electric strain sensors are connected to amplifier of electric signals and unit of their registration.

EFFECT: increase of clothes and garments quality.
