Sewing machine

Abstract

A sewing machine includes a presser foot ( 2 ) mounted pivotably about a horizontally aligned axis ( 1 ), which is configured to cooperate with an undertransporting apparatus disposed on a support area ( 3 ) for a material to be sewn, which includes two material sliders ( 4, 5 ) mounted movably with respect to one another for the continuous transport of the material in a feed direction. Both material sliders ( 4, 5 ) are configured to be extended horizontally when viewed in the feed direction both in a region before and in a region after the axis ( 1 ) of the presser foot ( 2 ).

1 . A sewing machine comprising a presser foot ( 2 ) mounted pivotably about a horizontally aligned axis ( 1 ), which is configured to cooperate with an undertransporting apparatus disposed on a support area ( 3 ) for a material to be sewn, which comprises two material sliders ( 4 ,  5 ) mounted movably with respect to one another for the continuous transport of the material in a feed direction, 
       wherein both material sliders ( 4 ,  5 ) are configured to be extended horizontally when viewed in the feed direction both in a region before and in a region after the axis ( 1 ) of the presser foot ( 2 ). 
     
     
         2 . The sewing machine according to  claim 1 , wherein the material sliders ( 4 ,  5 ) are formed from a plurality of rows of teeth ( 6 ) which extend parallel to one another and intermesh displaceably. 
     
     
         3 . The sewing machine according to  claim 1 , wherein the material sliders ( 4 ,  5 ) are each disposed on a support element ( 7 ,  8 ).

         5 . The sewing machine according to  claim 3 , wherein both support elements ( 7 ,  8 ) are preferably each rotatably hinged at one of their ends on a crank ( 9 ) in order to achieve a horizontal movement of the material sliders ( 4 ,  5 ). 
     
     
         6 . The sewing machine according to  claim 5 , wherein the cranks ( 9 ) for the support elements ( 7 ,  8 ) are disposed on a common axis of rotation ( 10 ). 
     
     
         7 . The sewing machine according to  claim 6 , wherein the cranks ( 9 ) for the support elements ( 7 ,  8 ) are disposed on mutually opposite sides of the axis of rotation ( 10 ). 
     
     
         8 . The sewing machine according to  claim 3 , wherein both support elements ( 7 ,  8 ) are preferably each displaceably connected to a guide ( 11 ) at their other ends to achieve a vertical movement of the material sliders ( 4 ,  5 ). 
     
     
         9 . The sewing machine according to  claim 8 , wherein the the guides ( 11 ) for the support elements ( 7 ,  8 ) are disposed on a common axis of rotation ( 12 ). 
     
     
         10 . The sewing machine according to  claim 9 , wherein the guides ( 11 ) for the support elements ( 7 ,  8 ) are disposed on mutually opposite sides of the axis of rotation ( 12 ).
