THE MOVEMENT OF THE TRUNK IN THE FRAME AS A BASIC
TECHNICAL RULE OF THE WORK OF THE FRAME.


The governement of the Federative Republic of the Peoples of Yugoslavia
prescribed in the end of last year an order for the introduction of the technical
ruling of the work in all enterprises. The determination of the operative time of
work on the machine with mechanical movement is done by tecnical calculation
of the time. The basic tecnical normativ of this calculation for the frame is the
movement of the trunk per 1 walk of the saw frame. Analysing the whole process
of the calculation and of the kinematics of the frame, the author comes to the
principal conclusion, that, because of the condition of our installations,
the koeficient of the useful walk of the saw frame must be included into the formula
for the calculation of the movement. Because of existing kinematic relations at
the frames on our managements, it will be necessary, to fixe certainly the
useful walk of the saw frame, to indicate the frames. Only by an indicator diagram
it is possible to accomplish the rectification of the mechanism for the movement, and
the existing koeficient of the useful walk of the saw frame fixe and include into
the calculation. Besides the work of the frame must be measured by chronometer, to
find out the norm of the operativ time of the frame as sure as possible.


After all he describes in short treats the limits of the rationality of making
use of producting capacities of the frame.
