Darts and pleats appear to be simple seams at first sight, but they have a great impact on the fitting shape of trousers, skirts and blouses as well as on the location of the piped pocket on the rear side of trousers. One basic problem with these seams is that the sewing part is placed over a blade. In doing so, the sensitive materials (stretch, among others) are stretched and drawn. This has an unfavourable impact on the sewing result. In order to counter this problem, we have developed the automatic short seamer BASS 5950.
The use of the BASS 5950 ensures an enormous gain in productivity and seam quality, and overlapping working method as well as consistent sewing results with different materials.
The pre-programmed seam is selected on the control panel.
Three marking lights ensure accurate positioning of the sewing part on the pre laying station.
The pre laying station with the sewing part positioned and fixed by vacuum moves to the transfer station. This accepts the sewing part and moves to the programmed dart depth (controlled stepper motor, programmable in 0.1 mm steps). Now the clamp accepts the sewing part (X-axis) and feeds it to the sewing head (Y-axis).
At the end of the seam, the clamp brings the sewing part to the stacking position where the de-stacking operation takes place. During the stitching, the next sewing part can be positioned on the pre laying table. This moves in after reaching a specific clamping position. This provides completely overlapped working method.
The system must be operated as a workstation in standing position. The height of the table can be adjusted to the body height of the operator.
