Abstract

1406781 Control of D.C. motors CUTTERS MACHINE CO Inc 14 March 1973 [17 May 1972] 12277/73 Heading H2J [Also in Division D1] An electric drive motor for driving the reciprocating frame of a fabric laying machine is automatically reversed at the ends of the frame travel and has control apparatus whereby the speed can be selectively controlled to move the frame at the same speed in both directions of travel laying face to face or to move the frame faster in a non-laying direction when laying face-up or face-down. The frame 11 carries a fabric roll 15 and co-operates with a catcher 25 fixed to the bed 14 of the machine. A fixed ramp 49 co-operates with switches 43, 44 to define lowspeed end parts of the travel and plungers 104, 111 co-operate with stops, e.g. 105, at the end of the travel to operate switches which reverse the field energization of the motor to reverse the drive. The various maximum speeds are preset on potentiometers (62 low speed) (64 highest speed) which control the bridge connected SCR's (88, 89) through a transistor amplifier circuit, Fig. 4 (not shown). The motor (28) is connected in parallel with the SCR arrangement and with a dynamic brake circuit (40) used to slow the motor when switches 43, 44 are operated. Two potentiometers (66, 67) are used for setting the required travel speeds which differ with the mode of operation and a selector switch (73) enables connection in one position to one potentiometer for forward motion and to the other potentiometer for reverse motion (face-up or face-down laying) and in the other position enables connection to only one potentiometer for both forward and reverse motion (face to face laying).
