Abstract: A portable impact type unit for mechanical hinged connection of the ends of conveyor bands with textile cord has housing where there are installed pressing elements for fixation of conveyor band at pressing-in the cramps, support plate, in the slots of that one there are placed cassettes of U-like connection elements for fixing those by t-like cramps to the ends of conveyor band; driving plate, impact punch; in the housing there is installed the matrix with working profile for bending and pressing in --like cramps with horizontal surface. Working profile for bending and pressing in -like cramps of the matrix is made as parabolic surface where value of lowering of the --like cramp corresponds to argument with maximal value equal to xmах=cos60°*(0.45-0.55) of the band thickness, and its position with respect to the vertical axis of the stands of the -like cramp corresponds to function with maximal value equal to уmах=sin60°*(0.45-0.55) of the band thickness; parabolic surface is connected to horizontal surface of the matrix at obtuse angle and installed with possibility of contact with the end of the e-like cramp for bending at angle not larger than 60°; at that the matrix at the housing is installed with possibility of displacement along the support plate; profiles of the matrix for bending and pressing-in the o-like cramps are separated from each other by distance corresponding to length of displacement of the matrix at change of positions at support plate and equal to length of bended at pressing end of the --like cramp. Unit for mechanical hinged connection of the ends of conveyor bands has fixed with --like cramps to each end of conveyor band U-like connectors hinged to each other with flexible rod; the U-like connectors are made plate-like. Length of link of the o-like cramp is equal to 0.9 – 1.1 of thickness of the band, and the bases of the stands have, respectively to thickness of the band, linear dimensions equal to the sum of thicknesses of conveyor band with attached to its ends plates of U-like connectors and thickness of its ends, those have length equal to 0.45 – 0.55 of thickness of the band and half of length of the cramp link; the sharp parts of those have dimensions equal to diameter of the cross-section. Mechanical hinged connector has plates of U-like connectors fixed with f-like cramps to the end of the band, with certain distance. The U-like connectors are installed with separation corresponding to the following expression: L1=t*n1, where L1 – distance for U-like connectors; t – distance between e-like cramps in U-like connector; n1 – positive integer from 1 to value equal to the number of -like cramps in the U-like connector; at that the width of the plate of U-like connector is determined by equation: L2=L1-c=t*n1-с, where L2 –width of the plate of the U-like connector; c – gap between plates of U-like connectors, the width of the hinge loop of the U-like connector is chosen from the equation: L3=L1/n2-с/2, where L3 – width of the hinge loop of the U-like connector; n2 – number of hinge loops of the U-like connector, and the width of the slot of the U-like connector if determined by the following relationship: L4=L1/n2+c/2, where L4 – width of the slot of the U-like connector.
