The article establishes the actuality of the research of energy-power parameters
of book block processing by tools without an individual drive. An experimental test
bench has been designed with purpose to perform the research of conveyor drive of
perfect binding machine upon a condition of use the cylindrical milling cutter without an
electromechanical drive. The experimental test bench has been mounted on perfect binding
machine Trendbinder (Muller-Martini, Switzerland). Such an approach gives grounds to
assert the maximum approach of experiment conditions to production. The article shows
the character of torques change depending on tractive effort. The author has discovered
that the increase of book block transportation velocity causes the dynamic improvement
of chain conveyor vibrations. The study analyses the reasons of onset of vibrations in
conveyor chain of perfect binding machine and substantiates their decrease with chain
velocity increasing. The article shows that maximum torque values on drive sprocket
increase with velocity increase of book block transportation. Analytical dependencies of
work computation needed for blocks spine processing by cylindrical milling cutter have
been achieved by the approximation of experimental curves. The reliability coefficient
of experimental curves approximation by trend line is k=0.92–0.97 gives reasons to
assert reliability of results got by analytical processing of trend line by polynomial of
the six degree. The study evaluates polynomial coefficients for the studied book blocks.
The author evaluates dependencies for power calculations of conveyor drive upon a
condition of book blocks spine processing by the cylindrical milling cutter without an
individual drive. The article analyses the impact of blocks transportation velocity and
paper type on conveyor drive power. The study shows that use of the cylindrical milling
cutter without an individual drive for book blocks processing reduces the process energy
consumption by 1.5–2.2 kW compared to traditional technology.
