摘要： A thread feeding apparatus for a sewing machine which has a simplified mechanism for accuracy of manufacturing and improved durability so as to accommodate high speed sewing. The thread feeding apparatus for the sewing machine has upstream grippers for respectively gripping an upper looper thread and a lower looper thread, closed by a stitch forming device at the time of the stitch forming and opened at the time of the cloth feeding, downstream grippers for gripping the respective threads introduced from the respective upstream grippers, opened at the time of the stitch forming so that the respective threads are pulled by the stitch forming device and closed at the time of cloth feeding, and reciprocators which are respectively driven in a synchronous manner with a left needle, a right needle, an upper looper and a lower looper, at the time of cloth feeding. The reciprocators shift the respective threads in thread paths extending between the respective opened upstream grippers and the respective closed downstream grippers to pull off a thread quantity necessary for forming a stitch and, at the time of stitch forming, release the respective threads.

摘要： An embroidery machine has its main shaft provided with a cam for controlling the thread takeup at an embroidery needle bar. A cam follower of the transmission arm of the pivotal thread-guide lever is held against the cam by a force-generating means such as a spring or a fluid-operated cylinder and a device is provided for swinging the thread-guide lever into a selected other position, e.g. for thread cutting.

摘要： A sewing machine for automatic thread taking-up and threading comprising a guide groove for guiding a needle thread to a threading preparatory position in the vicinity of a needle bar via a thread taking-up preparatory position intersecting a thread take-up moving area, a sewing machine motor driver for extracting the needle thread along the thread take-up moving area and for instructing a thread take-up to catch the needle thread, a pulse motor driver for threading the needle thread to an eye of a needle, a threading switch for generating signals, and an electronic control circuit for controlling the pulse motor driver and the sewing machine driver at prescribed timings in response to the signals from the threading switch. In the sewing machine, an operator has only to prepare a needle thread along the guide groove and push the threading switch. The electronic control circuit then controls the pulse motor driver and the sewing machine driver for the thread taking-up operation and the threading operation, respectively. Any operator can operate the sewing machine with easiness because the thread take-up operation and the threading operation are automatically performed without complicated cam mechanism or linkage mechanism. In addition, the sewing machine is easy to manufacture and the timing of operations can easily be adjusted.

摘要： A sewing machine for automatic thread take-up and threading, which comprises a guide groove for guiding a needle thread from a bobbin to a threading preparatory position via a thread take-up preparatory position, a sewing machine motor driver and a sewing machine motor for extracting the needle thread at the thread take-up preparatory position along the thread take-up moving area and for taking up the needle thread using a thread receiver and/or a thread take-up, and a thread positioning member for keeping the end of the needle thread guided to the threading preparatory position and for positioning the needle thread in front of or at the rear of the eye of a needle, a threading member for performing the threading operation of the needle thread, and a prohibiting member for prohibiting the threading operation until the thread take-up operation is over. In the sewing machine, the thread take-up operation and the heading operation are automatically and successively performed. The needle thread is kept at its end by a thread positioning member and a tension member is opened during the thread take-up operation. Therefore, the end of the needle thread is not drawn toward the thread take-up. The operator has only to put the needle thread along the guide groove and does not have to prepare the needle thread twice for the thread take-up operation and the threading operation.

摘要： A sewing machine including an automatic thread taking-up operation which comprises an arm of a thread take-up projecting beyond a thread holding member, a needle thread carrying member for introducing the needle thread into the thread holding member when the thread take-up swings toward one end of a thread guide, a pathway for the needle thread formed in the thread holding member, a blocking member for preventing the needle thread from slipping out of the thread holding member, and a crossing member for helping the needle thread carried beyond the thread taking-up member to cross the thread guide. The sewing machine can easily perform thread taking-up operation and threading operation while the thread take-up swings vertically.

摘要： A quilting machine employs bobbin holders which support bobbins each having a conical lower portion ending in a point. A plurality of hooks are driven in an eliptical path to engage and pull down a loop of thread formed by insertion of a needle through a needle plate and the partial withdrawal thereof. The hooks keep the loop open and pull it down so that it passes over the pointed lower end of the bobbin. In order to facilitate engagement of the loop over the bobbin, the bobbins are maintained in sloped fashion. A thread take-up mechanism pulls up the loop of thread with one of the strands of the loop passing behind the bobbin between the bobbin and the bobbin holder to form a lock stitch.
