Application of waistbands to garments
View Patent ↗A method of attaching a waistband to a garment is disclosed which comprises providing a strip ( 26 ) of waistband fabric having outer portions more extensible than the centre section, and presenting the fabric to a sewing machine through a folder ( 18 ) for attachment to a garment, characterized in that the folder is angled to the sewing zone ( 16 ) whereby to force the outer sections of the waistband strip to proceed faster than the central section resulting in a curve being formed during attachment to the garment. Since the strip does not have a shape until it is treated in accordance with the invention, it may be provided on a reel for continuous operation. Moreover, the angle at which the folder presents the waistband to the sewing zone can be altered whereby to give shapes that are not of constant curvature. The folder may be mechanically linked using, for example, a pneumatic or hydraulic cylinder arrangement, to a knee-switch or foot-switch, to enable different degrees of curvature to be achieved at the operator's control.
1. A method of attaching a waistband to a garment which comprises the steps of:
providing a strip of waistband fabric having outer sections more extensible than a centre section,
presenting the fabric to a sewing machine through a folder for attachment to a garment,
angling the folder relative to a sewing zone to force the outer sections of the waistband strip to proceed faster than the centre section resulting in a curve being formed during attachment to the garment, and
altering the angle at which the folder presents the waistband to the sewing zone during attachment of the fabric to the garment to incorporate shapes that are not of constant curvature.
2. A method as claimed in claim 1 wherein the strip which will form the waistband has outer sections more extensible than the centre section so that, when folded, one side is more extensible than the other.
3. A method as claimed in claim 1 further including the step of mechanically linking the folder to an adjustment device to enable different degrees of curvature to be achieved at an operator's control.
4. A method as claimed in claim 1 further including the step of stabilizing a work piece as the work piece leaves the swing zone by passing the work piece under a pair of rollers that are mounted downstream of the sewing zone.
