An infinite throat sewing machine material movement apparatus with a first roller where the first roller is connected with a first motor. A second roller is connected with a second motor, a first encoder pipe connected with a first encoder motor, a second encoder pipe connected with a second encoder motor; and a controller is connected with the first motor and the second motor and the first encoder motor and the second encoder motor. The controller operates the first motor and second motor to rotate the first roller in a first direction and the second roller in a second direction such that material connected with the first roller and the second roller is held at a selected tension and where the controller operates the first encoder motor and the second encoder motor to override the first motor and the second motor such that material connected with the first roller and the second roller moves in the first direction or in the second direction while maintaining the selected tension.

A needle plate has a needle hole and a guide hole communicating with the needle hole. The guide hole is located near a front side of a sewing machine and positionally deviated from an up-down movement trajectory of a sewing needle in a rotating direction of a rotary hook. The needle plate has a groove formed in front of the needle hole and extending from the guide hole in a direction opposite to the rotating direction of the rotary hook. While the groove is open upward and at its portion leading to the guide hole, the other portions of the groove are defined by a bottom surface and side walls. In a sewing operation, depending on a direction in which a member holding a sewing workpiece moves, the lower thread passes through the guide hole to be guided to the front of the needle hole via the groove.

A sewing machine includes a column, a bed, an arm, and an input interface. The column extends in an upper-lower direction. The bed extends in a first particular direction from the column at a position above a lower end of the column. A first direction includes the first particular direction and a first opposite direction opposite to each other. The first direction is perpendicular to the upper-lower direction. The arm extends in the first particular direction from the column at a position spaced upward from the bed. The input interface is arranged on a front plate. The front plate is a plate located at an end of the arm in the first particular direction. The input interface is an interface for operating the sewing machine.

A thread drawing device includes a drive assembly which includes a drive wheel that has a working platform for supporting a thread, the thread has a fixed end fixed on an object and a movable end carried by a tool. The thread drawing device includes a pressing assembly which includes a pressing member configured to move between a first position at which the pressing member engages the working platform to clamp the thread to be pulled therebetween and a second position at which the pressing member disengages from the working platform to release the thread to be pulled. The thread drawing device includes a motor configured to rotate the drive wheel when the pressing member is at the first position so as to move a loose part of the thread at the fixed end from the fixed end to the movable end.
