An apparatus for automatically controlling of the pressure exerted on sewing machines a presser foot.

摘要

An apparatus for automatically controlling a presser foot of the pressure exerted on sewing machines, preferably industry - sewing machines, with a pneumatic system - system, the at least one cylinder (4) contains, in which a piston (5) slides, characterized in that the piston (5) directly via a connecting part (6) with the shaft (2) of the presser foot (3) is connected, that a cylinder chamber of the cylinder (4) by means of a conduit means (8) is connected with a pneumatic control system, the at least a pressure regulator (10) for adjusting the pressure in the cylinder (4), and wherein the computer-controlled control system for determining and input of various options and working parameters is formed by the computer, the pressure in the case of all by the shaft (2) of the presser foot (3) to maintain a constant push-mode conditions exerted.
