Abstract

The present invention discloses a method and apparatus for applying patterning signals to electric patterning devices. Firstly, first electric signals are obtained from an object on which the original pattern is based and is displayed on a display means. Second electric signals are also displayed on said display means for defining an area of said selected pattern. The first and second signals are monitored so that said first signals can be corrected, if necessary. Third electrical signals are obtained corresponding to a portion of the first signal to be selected, and the patterning device and tools are controlled by said third electrical signals.

Dependent claims

A method for applying a pattern, corresponding to at least a portion of an object, to an article, said method forming basic pattern information which controls a machine for applying said pattern onto said article in accordance with a pattern information signal, comprising the steps of:

a. generating a television signal corresponding to said object;
b. generating a first electrical signal as a function of variations in said television signal resulting from at least one of the gradations, colors or irregularities in said object;
c. displaying said first signal on a display device;
d. generating a second electrical signal which can be displayed on said display device as at least one of a group of points or a group of boundary lines wherein the dimensions of the display of said second signal, horizontal to vertical ratio, the number of points and the position of the display of said second signal are independently variable;
e. displaying said first and second signals on said display device in a superimposed relationship;
f. varying said first signal and thus the display thereof, such that said first signal corresponds to at least a portion of said object;
g. monitoring the variations of said first signal with said second signal superimposed thereon on said display device;
h. generating a third electrical signal corresponding to said varied first signal at the points at which said second signal is superimposed thereon;
i. applying said third signal to said machine for applying said pattern to said article for controlling said machine.

An apparatus for applying a pattern to an article, said apparatus forming a basic pattern signal in accordance with a pattern information of the original figure and controlling a knitting machine by said basic pattern signal, comprising:

a. at least one television camera which is used for reading out said pattern information,
b. display means for displaying thereon the output of said television camera,
c. a plurality of Schmit trigger circuits which separate the electrical output signal of said television camera into the desired voltage levels and which convert the separated electrical signals into rectangular wave signals, each having a pulse width which is proportional to said voltage level,
d. logical circuits which convert the plurality of said rectangular wave signals into coded signals,
e. a synchronizing circuit which receives the output of said television camera and generates a synchronizing signal,
f. an extract condition creation circuit which receives said synchronizing signal from said synchronizing circuit and extracts the coded signals which are within the desired range from a plurality of said coded signals,
g. a mixer circuit which mixes the output of said extract condition creation circuit and said logical circuits, by using said synchronizing signal from said synchronizing circuit,
h. display means which display the output of said mixer circuit, and
i. a control means which controls said knitting machine in accordance with the output of said extract condition creation circuit.
