PFAFF 3801

Quality standards

The pre-gathering of sleeves and the bridle-taping of armholes provide the basis for an ideal fit of the sleeve.
For these requirements the PFAFF 3801 provides a fully developed workplace which is precisely adjusted to the necessary working processes and quality demands and therefore serves as an important manufacturing resource for the work step `pre-gathering sleeves and bridle-taping armholes´.

Subclass - 4/071: without automatic bridle tape feeder
Subclass -12/071: with automatic bridle tape feeder

Features

• Differential top- and bottom feed
  Due to the differential feed it is possible to recall or programm the desired fullness manually (by knee switch) or on the control panel.
  The floating foot supports the even distribution of fullness and guarantees smooth seams.
  By operating the knee switch, it is possible to change between flat sewing and gathering as required, with programmable sewing the change happens automatically after Teach-in.
• Touch-screen-control-panel P1 with integrated SD card reader
• Easy data transfer (from machine to machine) by a SD-card (USB)

• Seam parameters such as amounts of fullness or the number of stitches are combined in one program
• Programme selection:
  0 = manuel sewing
  1 und 2 = sewing with installed programmes (knee switch)
  3 bis 49 = programmable sewing (with up to respectively 15 seam sections for the left and right seam)
• Sleeves can be sewn both flat or closed
• The sewing process can be followed and controlled in the display
• The sewing program is created using the Teach-In process or via direct data input on a standard size
• Size grading and mirroring (left/right) take place automatically. The operator is guided through these processes via simple symbols
• Automatic bridle tape feed and tape cutting (subclass -12/071)

• Central lubrication of sewing hook and needle bar. (semi dry sewing head)
• Closed gearcase with long-time lubrication pad
• Lifetime sealed maintenance-free bearings
• Built-in adjustment gauges for easier and faster adjustment
