摘要： PROBLEM TO BE SOLVED: To reduce erroneous sewing and a position deviation in sewing without deteriorating economic property and working efficiency.
SOLUTION: A sewing machine includes: a fabric feeding mechanism 40 for placing and feeding a flap fabric F; a fabric position sensor 30 having light emitting elements 33 for emitting light to the flap fabric and light receiving elements 31 for receiving reflection light from a reflection surface 41c which is blocked off by the placement of the flap fabric; a control means 60 for controlling sewing, based on the front end and rear end positions of the flap fabric, which are detected by the fabric position sensor; and a deterioration position data acquiring means 61 for allowing a storage means 63 to store deterioration position data, expressed with the feeding positions of the fabric feeding mechanism, by defining an area, where the amount of the reflection light by a light receiving sensor is reduced in a state without placing the flap fabric, as the deterioration position of the reflection surface. When sewing is to be performed, the control means prevents the sewing when the feeding positions, in detecting the decrease and the subsequent increase of the amount of detected reflection light, respectively coincide with the front end and rear end positions of one deterioration area, performs the sewing when nothing is coincident, and reports an error when only one of them is coincident.

摘要： PROBLEM TO BE SOLVED: To provide a sewn matter carrier which can reduce the occupying area for a mechanism to move a sewn matter presser and realize cost reduction and convert the most of rotation force of a drive source to linear movement of the sewn matter presser. SOLUTION: A pair of output shafts 6a, 6b are placed in parallel and are possible to rotate clockwise and counterclockwise. One end parts of first links 7a, 7b are respectively fixed to the output shaft 6a, 6b. One end parts of second links 8a, 8b are rotatably connected to the other end parts of the first links 6a, 6b, respectively. A sewn matter presser 9 is rotatably attached to the other end parts of the second links 8a, 8b and a regulating link mechanism 10 to regulate the posture of either one of the second links 8a, 8b is equipped.

摘要： PROBLEM TO BE SOLVED: To ensure optimum, vertical/horizontal momentums of feed gear without preparing several kinds of vertical feed and horizontal feed cams having different eccentric amounts and without changing the combination of cams when such sewing conditions as the kind and thickenss of the fabric to be sewn are changed. SOLUTION: This machine comprises a vertical feed shaft rotating in linkage with rotation of a main shaft, a horizontal feeding rod loosely fitted to an ecccentric cam fixed at its one end to a rear portion of the vertical feed shaft and giving horizontal movement to a feed gear, a vertical feed arm loosely fitted at its lower end to an eccentric cam fixed to a front end of the vertical feed shaft and giving vertical movement to the feed gear. In the machine, at least one of the two eccentric cams is constructed to have a double eccentric cam structure, thereby making the maximum movement of the feed gear variable.

摘要： PROBLEM TO BE SOLVED: To prevent a matter to be sewed from being loosened and wrinkled between a tip pulling roller and a feed dog in the reverse feeding of the tip pulling roller. SOLUTION: When a cloth feeding means for transferring a matter to be sewed in such a manner that the cloth feeding direction can be changed normally and reversely selectably in a stitch forming position is laid in the reverse feeding state, the reverse feed quantity of a tip pulling roller engaged with the matter to be sewed from above ahead in the cloth feeding direction over the cloth feeding means to transfer the matter to be by rotation is controlled so as to be equal to or smaller than the reverse feed quantity of the cloth feeding means or the normal feed quantity of the tip putting roller.

摘要： PROBLEM TO BE SOLVED: To make it easy to control the oscillating amount of cloth feeding by converting the rotating motion of the main shaft of a sewing machine into oscillating motion of an oscillator, transmitting the motion to lengthwise motion of cloth feeding teeth through an oscillating lever, and making the lengthwise motion amount be variable by position adjusting of a rotation shaft to be the center of the oscillating motion of the oscillating lever. SOLUTION: An oscillating mechanism to convert rotation motion of the main shaft 1 of a sewing machine is composed of an eccentric cam, crank rod, etc. And the converted oscillating motion is transmitted to a feed shaft 11. Main feed teeth 3 equipped on a main feed oscillating bar 4 to feed cloth are vertically oscillated by the rotation motion of the main shaft 1 since upper and lower feed pieces 52 and an oscillating bar support shaft 54 are slidably inserted into guide grooves 4a, 4b formed on the main oscillating bar 4. A link mechanism including an oscillating lever 15 is equipped to transmit the oscillating motion of the main shaft 1 to the lengthwise motion of the main feed oscillating bar 4 and the rotation axis b1 to be the rotation center of the oscillating lever 15 is made position-controllable to make the lengthwise motion amount of the main feed teeth 3 be variable.
