Operation Description
(See section 4, simplified view)
The strapping head is in home position. The camshaft display indicator is on - 0 - position, and
the camshaft is blocked against rotation in anti-clockwise direction further than the - 0 - position
on the camshaft display. The switch B104 is activated, indicating that the shutter is closed.
With start of the strap cycle program, strap feeding will be initiated. While strap feeding the
motor M24 (see drwg. 464631, pos. 82, page 33) is running in clockwise direction. The small
clutch Y37 "high speed" (see drwg. 100.36, pos. 41, Page 43) of the transmission is activated
and the strap is fed through the chute system at high speed.
On re-entry of the strap into the head, the limit switch B102 positioned in the strap guide wedge
will be activated (see drwg. 464631, pos. 76, page 33). The activated strap feed switch initiates
the large clutch Y22 after a delayed time, causing the motor M24 to interrupt feeding after a
certain time, depending on the setting of the time relay. This setting directly influences the strap
overlap length. During strap feed the camshaft brake Y38 is energised.
Next step; strap being clamped, will be initiated. The motor changes into counter clockwise
direction, at the same time the strap drive brake Y36 will be activated and the "camshaft brake"
Y38 is de-energised. The large clutch Y22 will be activated and the camshaft rotates in
clockwise direction from position 0 into position 1. The proximity switch B106 "max strap tension
reached" will be activated for the first time. The camshaft stops at position 1 and the tip of the
strap will be clamped by the gripper (see drwg. 464655, pos. 8, page 39). Camshaft brake Y38
will be activated again. The strap drive brake Y36 will be de-activated.
