Programmed application of fullness

• The following work processes can be carried out on the class 3801 ;
  • Pre-gathering sleeves (sleeve head)
  • Sewing in an interface strip (when pregathering)
  • Bridle-taping armholes (jacket backs and fronts).
• Sleeves can be sewn both in closed and poen states.

Instruction for use

• For working with bridle tape it is recoommended that the machine be equipped with the tape feeder 91-084 381-90.
• When pre-gathering sleeves while simultaneously sewing in an interface strip,a bridle tape is no necessary. In this case it recommended to use the machine with therad trimmer(-1/071).
• It is now possible to sewing sleeves and to carry out the programmed application of fullness in one workphase (PFAFF3834-3/11). There are the following reasons for pre-gathering with the PFAFF3801:
  • The interface strip sewn in when pre-gathering with the 3801 fills out the fullness
    area in the sleeve better and prevents creasing in the front.
  • Almost the same amount of time is required as when sewing in directly, because in the direct process the interface strip must be sewn in using a separate workstep.
  • Shorter training time and low qualification-requirement when subsequently attaching the sleeve.
• With the PFAFF 3801 for pre-gathering and the PFAFF 3834 for sewing in the pre-gathered
  sleeve, you have the perfect, most effective combination in every respect.
