Abstract
Abstract Control apparatus of speed, position and specific functions for industrial sewing machines through a digital technique with a varying inductance input, comprising a spool (1) intersected by a shaft (2) activated by a lever (3) connected to the machine treadle. The different positions that the shaft (2) moves to in the spool (1) determine just as many differentiated inductance outputs. Said inductance outputs are transmitted to the machine electrovalves dedicated to the various service operations.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
44 words
Control apparatus of speed, position and special functions for industrial sewing machines, using a digital technique, characterized by the fact that it employs a variable inductance input and comprises a spool intersected by a shaft, run by a lever connected to the machine treadle.
Claim 2
Dependent Claim
44 words
Control apparatus of speed, position and special functions for industrial sewing machines, using a digital technique, characterized by the fact that it employs a variable inductance input and comprises a spool intersected by a shaft, run by a lever connected to the machine treadle.
Claim 3
Dependent Claim
65 words
Apparatus according to claim 1, characterized by the fact that the inductance, corresponding to each position of the shaft in the spool, is transmitted to the electrovalves, dedicated to the various working operations, by means of an electronic computer with numeric display, a technical panel and a synchronizer, forming an intergral part of the main camshaft of the sewing machine, and an electrovalve power actuator.
Claim 4
Dependent Claim
26 words
Apparatus according to claim 2, characterized by the fact that the computer numeric setters are able to memorize one or more positions of the machine camshaft.
Claim 5
Dependent Claim
29 words
Apparatus according to previous claims 2 or 3, characterized by the fact that the display permits continuous viewing, in the form of numbers, of the sewing machine camshaft position.
Claim 6
Dependent Claim
28 words
Apparatus according to the previous claims 2 to 4, characterized by the fact that the running of the brake-clutch unit is actuated by means of a digital technique.
Claim 7
Dependent Claim
31 words
Apparatus according to the previous claims 2 to 5, characterized by the fact that setting of the maximum speed which may be reached by the sewing machine is carried out electronically.
