Abstract
A method for operating the guide bars of warp knitting machines comprises feeding in to a computer desired lapping instructions, the computer being programmed to discriminate between permitted and prohibited lapping movements and being operative to prevent the attempted execution of prohibited movements. The computer can be programmed to test instructions against a set of mandatory rules, which proscribe lapping movements that would crash the guide bars, and may also be programmed to discriminate against ineffective lapping movements.
Claims11
A method for operating the guide bars of warp knitting machines to feed yarn to the needles thereof, said method comprising the steps of:
- (a) providing actuator means for causing lapping movement of said guide bars in response to operating electronic signals being transmitted to said actuator means;
- (b) programming a computer to distinguish between predetermined permitted lapping movements for said guide bars and prohibited lapping movements for said guide bars;
- (c) inputting guide bar lapping movement instruction into said computer;
- and
- (d) generating said operating electronic signals from said computer and transmitting said signals to said actuator means to cause lapping movement of said guide bars only when said input lapping movement instructions correspond to said permitted lapping movements for said guide bars.
Apparatus for operating the guide bars of a warp knitting machine to feed yarn to the needles thereof, said apparatus comprising:
- (a) actuator means for causing lapping movement of said guide bars in response to electronic operating signals transmitted to said actuator means;
- (b) computer control means including:
- (i) progamming means for programming said computer control means to distinguish between predetermined permitted lapping movements for said guide bars and prohibited lapping movements for said guide bars;
- (ii) input means for feeding input guide bar lapping movement instructions into said computer means;
- and
- (iii) means for gnerating said operating electronic signals and transmitting said signals to said actuator means only when said input guide bar lapping movement instruction correspond to said predetermined permitted lapping movements for said guide bar.
