New integrated workplace for closing rub-down seams, such as heel-, front- and side seams on street shoes, slippers and leg boots. The PFAFF 3806 is equipped with two-thread chainstitch high-speed seamer head PFAFF 5487 with drop feed and variable top feed, high lift and adjustable top feed pressure, which ensures consistently high quality. Reinforcing tapes, which may be applied from top impart greater durability to the seams and prevent fine leathers from being pulled out of shape. Automatic control sequences (via parameter or photocell) reduce the manual handling and increase the process reliability and output.
