Abstract
A method for transferring an embroidery frame backward in case of thread breakage, includes the steps of: a) detecting the thread breakage to generate a thread breakage signal if the thread breakage occurs at a needle contained in needle holders; b) generating the control signal to control an embroidery-frame driver in response to the thread breakage signal; and c) transferring the embroidery frame backward in response to the control signal.
Claims27
An embroidery machine for transferring an embroidery frame backward in case of thread breakage, the embroidery machine including the embroidery frame and needle holders holding needles, comprising:
- detection means for detecting the thread breakage to generate a thread breakage signal if the thread breakage occurs at a needle contained in the needle holders;
- transfer means for transferring the embroidery frame backward in response to a control signal;
- control means, coupled to said detection means and said transfer means, for generating the control signal to control said transfer means in response to the thread breakage signal;
- and
- storage means, coupled to said control means, for storing embroidery-frame transfer distance data.
An embroidery machine for transferring an embroidery frame backward in case of thread breakage, the embroidery machine including the embroidery frame and needle holders holding needles, comprising:
- generation means for generating an embroidery-frame transfer request signal in response to a user request if the thread breakage occurs at a needle contained in the needle holders;
- transfer means for transferring the embroidery frame backward in response to a control signal;
- and
- control means, coupled to said transfer means and said generation means, for generating the control signal to control said transfer means in response to the embroidery-frame transfer request signal.
