5.5 Setting of engaging and disengaging of
the trimming mechanism, of the engaging
and carried lever stop
5.5.1 Description
The material trimming mechanism is formed by a moving part
- lever (1) on the shaft, which is connected by means of the
lever (2) and the connecting rod (3) with the trimming
mechanism drive, and by a carried part - lever (4), the
component part of which is also the knife holder (6) by means
of the shaft (5).
The levers (1) and (4) are set up by means of mutually clamping
joints in such a way, so that the carried lever (4), when being
turned by 90
°
, fits into the moving lever (1) by means of the
pawl (7).
When the trimming mechanism is engaged, the carrying part
is connected with the carried pawl (7) which controls at the
same time the mechanism of the trimming drive (8).
The trimming mechanism, which is situated on the vertical
divided shaft (5) is put into its working position by the hand
lever (9) in turning it to the right. After having engaged the
trimming mechanism, the hand lever returns into its starting
position up to the stop (10) by means of the torsion spring
(11).
The trimming mechanism is disengaged by depressing the
push button (12) which loosens the pawl (7) from the slot in
the lever (1).
At the same time, the operating device of the microswitch is
being shifted and stops the running of the driving motor.
5.5.2 Setting of the engaging lever stop
The stop screw (1) is to be screwed in and locked by the nut
(2)in such a way, so that the engaging lever (3) is in its starting
position perpendicularly to the longitudinal axis of the
machine.
5.5.3 Setting of the position (shifting)
of the carrying lever
When the carrying lever (1) is in the half of the lift of its reversing
motion, the pawl (2) is to be situated symmetrically to the axis
of the switching off push button (3).
5.5.4 Setting of the carried lever stop
The stop screw (1) is to be screwed in and locked with the nut
(2) in such a way, so that, when being the trimming mechanism
disengaged, there is a clearance of 1 mm between the engaging
lever pin (3) and the pawl (4).
