Description

чающа с  тем, что, с целью обеспечени  плотного прилегани  к верхн ку и криволинейным участкам ножек арочной крепи , в одной из плоских сторон зат жки выполнены выемки по всей ширине плиты с радиусом, равным внешнему радиусу арочиой крепи, причем образуюш,а  выемки параллельна поперечной стороне зат жки.This is so that, in order to ensure a close fit to the top and curvilinear sections of the arch support legs, notches are made across the entire width of the plate with a radius equal to the outer radius of the arch support in one of the flat sides of the fixture, and the notches are parallel to the transverse side tightening
