Spread Drive System
Use the illustrations (Figure 5-20, 5-21) below
to identify the mechanical components of the
spread drive system, which actually consists
of separately powered upper and lower drive
subsystems.
Upper Spread Subsystem
In the right endframe, the upper spread motor
(A) powers the upper spread subsystem. A shaft
from this motor extends directly into a drive
pulley (B).
This pulley drives a belt (C) which spans the
width of the machine to another pulley in the left
endframe (D) which sits on a jackshaft (E).
When the belt moves, the two spreader jaws,
one attached to the upper portion of the belt, the
other to the lower, move in opposite directions.
The action of the spreaders is pneumatically
controlled.
Lower Spread Subsystem
There are two lower spread subsystems, each
an exact mirror of the other. In each endframe,
a lower spread motor (F, O) powers each lower
spread subsystem.
A shaft from each motor extends directly into
a drive pulley (G, P). These pulleys drive belts
(H, Q) which in turn power two sets of oppositely
turning pulleys (I-J, R-S). These pulleys turn two
sets of shafts (K-L, T-U).
The shafts drive two sets of pulleys (M-N,
W-V), which power the lower spreader belts,
causing them to stretch the flatwork toward the
left and right sides.
