Abstract
The efficiency of primary wood processing largely depends on the optimal utilization of macines
and tools. Beyond the rational use of sawlogs in sawmilling, the profitability and effective operation of
sawmill capacities critically rely on the efficient application of primary processing machines. These
machines are primarily tasked with transforming logs into semi-finished products, through which logs
are converted into sawn timber through the sawing process. Among the most implemented machines for
primary processing are band saws. These types of primary machines allow individual log sawing, where
each log is processed separately according to its dimensions and quality class. In such operations,
determining the technological capacity is essential, defined as the volume of logs a machine can process
within a given timeframe. A key factor affecting technological capacity is the processing time per log,
which represents the cumulative duration of all sawing operations and factors involved in sawing , such
as log rotation, number of cuts, log length and other related activities. The processing time can be divided
into components dependent on the machine’s technological parameters and those influenced by the
organization of production within the sawmill. This study presents a detailed analysis of processing
times for Scots pine (Pinus sylvestris) sawlogs using a vertical band saw.
