AI Technical Summary

Benefits of technology

The present invention provides a frame, machine, and method for sewing upper pillows on covering shells for mattresses. The frame simplifies the process, allowing for easy and efficient coupling of the pillow and covering shell. The machine produces consistent quality, while the method requires minimal labor. The frame, machine, and method are low cost, easy to use, and safe in practice. The technical effects include simplifying and streamlining a process that was previously cumbersome, resulting in improved efficiency and quality.

Problems solved by technology

This therefore determines a considerable increase in the costs of mattresses provided with these pillow tops, which relates to the cost of the labor necessary for their production.

Furthermore the production times are rather long, with consequent production limits that are linked to the need for manual intervention on each one of the mattresses: an increase in productivity is necessarily associated with the hiring of additional specialist craftworkers, who are able to carry out the necessary work.

The artisan nature of the work, furthermore, does not permit a standardization of the product within narrow margins, without providing for a high number of production discards.
