Title: Industrial sewing machine
Inventor: KOSMAS NIKOLAOS
IPC: D05B3/08
Filed: 1997-10-28
Granted: 1999-08-21
Abstract: An industrial sewing machine for the completion of a button hole comprises a needle holder that is connected via an arm to means which ensure a forward and backward motion perpendicular to the direction of the needle. The aforementioned means bring an extremity of the arm turned away from the needle holder into a forward and backward motion perpendicular to the direction of the arm. The arm carries a cam which slides in a fitting manner in a groove of a first body that in itself slides in a groove of a further body which is connected to a fixed portion of the device. Because the first and further groove extend under a non-perpendicular angle to the direction of the arm, the arm is forced to move to and fro with. The amplitude of the motion is proportional to the cosine of the angle of the groove and eventually determines the stitch bite of the needle, which width is thereby easily adjustable by means of the pivotably suspended first body. The cutting space may be adjusted by sliding the first body within the groove of the further body.
