Tape feeder No. 91-084 381-90 (option) for sewing bridle tapes. 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.
