Abstract
An apparatus for sewing stitch-group seam patterns of a longitudinal direction that runs lengthwise or crosswise of an edge of a work piece comprises a table with a slab with an operator's side allocated thereto. Disposed on the slab is a bearing plate with a sewing machine resting thereon by its base plate. The slab is pivotable by a right angle between a first and a second working position and about a pivot bearing with an axis that is perpendicular to the slab. In this way, the position of the sewing machine relative to the operator's side is modifiable by a right angle.

An apparatus for sewing buttonhole seam patterns of a longitudinal direction that is one of lengthwise or crosswise of an edge (43, 48) of a work piece (41, 46), comprising
- a table (10),
- which has a stand (11) and
- a slab (9), and
- which an operator's side (16) is allocated to;
- a sewing machine (1),
- which has one needle bar (7) that is reciprocatingly drivable,
- a base plate (3),
- a lengthwise front (32), and
- a frontal end (33) in vicinity to the needle bar (7);
- a bearing plate (17),
- which continuously rests by it's full surface on the slab (9),
- which the sewing machine (1) rests on by its base plate (3), and
- which is displaceable by a right angle between a first and a second working position about a pivot bearing (24) with an axis (25) that is perpendicular to the slab (9),
- wherein, in the first working position, the lengthwise front (32) is turned towards the operator's side (16), and
- wherein, in the second working position, the frontal end (33) is turned towards the operator's side (16);
- an absorption coating (23),
- which is disposed between the bearing plate (17) and the slab (9), and
- which is made of felt;
- and a detent (35),
- which arrests the bearing plate (17) in the first working position and the second working position,
- which comprises a bolt (34),
- which is insertable in holes (35, 36) in the bearing plate (17) and the slab (9).
