Machine for assembling and sewing sleeve-head rolls.

Sleeve-head rolls may be made up of 1 to 7 pieces each and the pieces may be sewn flat or with effect.

The machine consists of the following devices:
• a rotating disc with 8 divisions on which the pieces of the sleeve-head roll are put
• a device for assembling the sleeve-head roll
• a robot with a gripping hand with 7 grippers for moving the sleeve-head roll under the sewing machine
• a PFAFF sewing machine mod. 3801-3/071, but a different type may also be installed
– an electrical panel with PLC and color operator panel

During the rotation of the disc step by step, one or more operators put the pieces of the sleeve-head rolls into the respective shapes, and at the same time, there is a device that assembles them.

The robot picks up the assembled sleeve-head roll and moves it under the sewing machine for stitching.

All these operations are performed in synchronism without pauses.

The machine produces the right sleeve-head rolls separately from the left ones; it is not possible to produce the pair consecutively.

Machine is suitable for the production of sleeve-head rolls for both men and women.

The rolls may be made up of 1 (one) to 7 (seven) pieces each and the pieces may be sewn flat or gathered.

This machine is composed of n.2 storage areas, each of which may contain up to a maximum of 7 (seven) containers for the pieces which make up the roller, a loading device for collecting the pieces, an automatic unit for assembly of the pieces making up the roller, an automatic sewing unit which includes a sewing machine (an overlock machine with double transportation or an ordinary sewing machine with knotted stitch bobbin).

During automatic operation, the loading device collects the pieces from one storage area while the other one remains free, thus enabling the user to load the containers.

In this way, the machine works continuously and never stops. The autonomy of one storage area and its containers loaded with pieces is about 30 minutes. Only a few minutes are needed to load the containers again, and during this interval the machine continues to work picking up the pieces from the other storage area.

This timing enables the user to easily take care of two machines simultaneously.

The whole machine is handled by an electronic programmer and various data are visualized and various controls are performed by an operator’s panel with a keyboard and liquid crystal display.
