Abstract
Abstract Method and apparatus for making a record carrier for an automatic embroidery sewing machine to detect amounts of longitudinal, lateral and angular movements of a cloth frame moving device, amplitude detection of the machine needle and start-stop instructions for the machine, with rotary pulse generators that generate pulses for the various movements. A magnetic record carrier records the pulse trains taken as outputs of the pulse generators.

Claim 1
Independent Claim
156 words
A method of making a record carrier for controlling an automatic embroidering sewing machine wherein an operator sews a selected embroidery design with an automatic sewing machine having a sewing needle comprising the steps of: providing a cloth frame assembly having a stretched workpiece supported thereon; moving said cloth frame distance amounts in X-axis and Y-axis directions and in an angular rotary direction during the sewing of said design; moving said needle by a distance amount in an X-axis direction during the sewing of said design; detecting the distance amounts of the various movements of the respective cloth frame assembly and needle by the use of individual rotary pulse generators; generating output pulses from said pulse generators, which pulses represent said distance amounts; recording said output pulses as master record trains in a magnetic record carrier; whereby said recorded record carrier may be played back to control an automatic embroidering sewing machine to reproduce said design.

Claim 3
Dependent Claim
177 words
Apparatus for making a record carrier for controlling an automatic embroidering sewing machine wherein an operator sews a selected embroidery design with an automatic embroidery sewing machine having a sewing needle comprising in combination; a first pair of rail members positioned parallel to each other and spaced from one another in the Y-axis plane; a second pair of rail members positioned parallel to each other and spaced from one another in the X-axis plane; individual rotary pulse generators connected with said first rail member pair, said second rail member pair, and said cloth frame assembly, respectively; each said pulse generators having a means to detect the amounts of movements on the respective X-axis and Y-axis planes and the amount of the variation of the rotation of said cloth frame assembly and a means to generate output pulses which represent said amounts; means connected to said pulse generators to record said output pulses on a magnetic record carrier, whereby said recorded record carrier may be played back to control an automatic embroidering sewing machine to reproduce said design.
