10.02 Sewing – Unit with cutter and rack
In contrast to the basic machine described in 10.01, the “Plus” machine sepa-
rates the pocket blanks after hemming with a cutter. An integrated extraction
device removes the loose threads during the cutting process and collects them
in a container under the work table. The individual pocket blanks are automati-
cally fanned out with an automatic racking device and placed on a round table.
