Assembling the mechanical dobby system
This section only applies if the loom is provided with a mechanical dobby system.
The mechanical dobby head has a wooden roller driven by a treadle. A chain of program
bars (also called dobby bars) runs along this roller. Each time you push the treadle, the roller
makes a quarter turn to bring the next program bar into the proper position for selecting the
shafts for the next shed.
The program bars have numbered holes that correspond with the shafts. The treadling is
programmed by inserting pegs into the holes of the program bars. These pegs push the
dobby hooks into their active position.
1. Mounting the dobby head
Open the hardware bag, which
contains:
•
2 threaded ends m6 x 134 mm with
knurled nut, washer, and barrel nut
•
2 screw hooks
•
1 bolt m8 x 70 mm with two large
washers, steel bushing and barrel
nut
•
2 screws 5 x 50 mm
•
1 screw 4 x 35 mm
•
1 wrench 13 mm
Insert the barrel nuts into the holes in
the sides of the middle section and
screw the threaded ends into them.
Slide the dobby head onto the threaded
ends. Make sure the black plastic knob
faces the front of the loom.
Slide the washers onto the threaded
ends and screw the knurled nuts on
tightly.
