Embodiment Construction

[0033] See attached drawings, especially figure 1 , 2 , reference numeral 10 represents a sewing machine, and the sewing machine 10 includes a head 14 and a base 12 . The base 12 has a table 20 on which the sheet-like fabric to be seamed is arranged. In the platen 20 , a hole 22 is provided for inserting a needle, which cooperates with a crochet needle (not shown in the figure) to realize the seam, and the crochet needle is arranged under the platen 20 .

[0034] Such as image 3 The nose 14 represented in includes:

[0035] - a fabric presser foot 24 whose position is controlled by an adjustment mechanism 26;

[0036] - a needle support 30 comprising two vertically movable cylindrical elements, hereafter called needle bars, to which the two needles 16, 18 are connected (in image 3 , only one needle bar 46 is visible);

[0037] - translation mechanism 38, 40, which translates the above-mentioned needle bar in a direction perpendicular to the direction of movement of the...

Abstract

Sewing machine (10) comprising a base (12) with a crochet and a head (14) that comprises a needle support (30), a fabric pressure foot (24) and its adjusting means (26), motor means (28) to make a needle sew together with the crochet, and lever means (32) to turn the rotary motion of the driving means into a vertical reciprocating motion. The needle support (30) in turn comprises at least two needle bars (46, 48) that are moved vertically by said lever means (32), and a connecting element (50) to couple the lever means (32) with at lead a needle bar (46, 48). Each needle bar (46, 48) is coupled with a needle (16, 18) through a respective thread and actuated selectively in the crochet in order to allow the sewing.

Description

technical field [0001] The present invention relates to a sewing machine, in particular an industrial sewing machine, suitable for mechanically seaming two or more sheets of fabric, while the two or more seams have different characteristics. [0002] The structure of this sewing machine is simple. In addition, this sewing machine can sew two sheet-like fabrics by using two threads having different characteristics such as color, thickness, and the like. Background technique [0003] As is well known, industrial sewing machines for mechanically seaming two or more sheets of fabric are generally designed according to different construction techniques depending on the operations to be performed. [0004] For example, units comprising one or more needles are known to seam articles of clothing such as jeans or slacks in general, overalls, shirts and the like. [0005] In the more common form, the above sewing machine type is provided with an upper head on which the needles are d...
