3.1. Description of the machinery
The machine is designed in a modular way which allows easy replacement or adjustment of all major technology units
and their individual parts. The machine consists of three basic parts:
The basis of each machine is a basic section to which you can connect, according the required cut length, the
extension sections. Basic and extension sections are tted with xed log loading surfaces, clamps of material and
angular adjustable rests.
On traversing sections moves the bridge of the band saw arm. The movement of the bridge on sections is manual -
pushing. On the bridge is placed the arm of the saw band which is placed on pulleys in order to move up and down.
The vertical movement of the arm is secured by a chain drive and worm gear. The movement of the arm is manually
operated by handle with arrestment. Precise adjustment of the arm height allows a circular scale indicator.
On the right side of the arm is a drive wheel of the saw band, driven by a spark ignition engine through a two-stage
belt gear. The clutch function represents the belt tension by the move of the entire motor, and a quick stop of the saw
band is secured by the brake shoe acting on the pulley. Position of the drive wheel pin is adjustable. On the left side
is located a tension wheel system. The movable body of the tensioning system moves in the cast iron guiding. Both
wheels are made of light alloy. In the circumference of the wheel is a machine cut groove for V-belt which forms the
interface between the wheel and the saw band. When cutting, the saw band is guided on both sides with guides of
hard metal.
3.2. Machine design
The basic design of the machine is possible, for an extra fee, to supply with special accessories.
The basic version:
Traversing frame, with length of 4.5 meters can cut logs of a maximum 3.45 m, is equipped with three sets of angular
rests and clamps. Material handling and clamping is manual.
Special accessories:
Extending sections: the total length of 2.25 m, it extends the cutting length of the basic section by 2.25 m, contains
1x angular rest and 1x clamp. The number of extending sections is not limited.
Angular rest with clamp: The basic version can be tted with a maximum of 6 angular rests with the clamp. Each
extension section can be equipped with a maximum of 3 angular rests with clamp.

The cutting lengths of the machine
To use the minimum length of the cut is necessary to place the clamp so that it is possible to clamp a log by two
clamps. Each extending section increases cutting length by 2.25 m
The noise measurements were made at machine steady state . During the operating state of a load, the most
commonly used technology process was measured. During operating statuses with the technology, the noise levels
were measured at a work station.
Measured according to EN ISO 3746:2011
The measured value exceeds the value specied in Decree 176/2008, Article 1.7.4.2. point, therefore it is necessary
during operation to use hearing protection devices and monitor the noise characteristics of the device.
The values of the measured noise level of the machine may vary according to the type of material and technology
used. These values are emission levels and may not represent the safe working level. Although the correlation
between emission levels and exposure levels, these values can not be used to reliably determine whether or not
further action is required. Factors that affect the actual level of exposure include the characteristics of the work area,
other sources of noise, etc., such as the number of machines and other adjacent processes. Maximum permissible
levels of exposure may also be different in different countries. This information is intended to serve users as better
tools for hazards and risk assessment.

20. Move the travel bridge cross to the parking zone at the start of the track
21. Remove the cut material from the saw
22. Adjust the height of the band for the next cut
4.4. Setting up and the clamping of material
Any material handling perform only when traversing bridge with a band saw arm is
Before loading a log (logs) on the table, it is necessary the angular rests tilted so that the logs does not fall from the
table. This device is also used for slabing when producing the squared timber. Log clamping is carried out by material
clamps. Clamps can be moved on the machine frame according the length the cut log. The actual log clamping is
performed using the spikes of the clamp that can be adjusted in height by folding clamp arms according to shape
and size of timber.
4.4.1. Angular rests
Serve:
• To prevent rollover of the log via the machine table when loading
• As the rest when clamping
• To create a right angle
Before cutting or traversing a saw bridge, the angular rests must be set in such a position (height)
4.4.2. Material clamps
They are collapsible, allowing their height adjustment. They can be used in two ways:
1. Clamping against angular rests
The wood is pushed by spikes set to the appropriate height to angular rests
2. Clamping against the stop on the frame cross member
Applicable only for prisms
Angular rests are folded and the clamps are adjusted as low as possible
saw band and the guide rollers.
The sliding guide roller of the saw band must be as close as possible to the material being cut. Material must not with
its length exceed the length of the cutting machine.
When loading material on the machine frame store it gently and avoid greater impact - it could cause deformation of
the machine or its displacement.
Check logs before their cutting (stones in the bark, mud, sand, tie pins, etc.). Very dirty logs is necessary, especially
from the side where the saw band get into the log, to get rid of bark or clean (e.g. with a wire brush).
