ОСОБЕННОСТИ БАЗИРОВАНИЯ БРЕВЕН НА ГОРИЗОНТАЛЬНЫХ ЛЕНТОЧНЫХ СТАНКАХ ПРИ ПОЛУЧЕНИИ ПИЛОМАТЕРИАЛОВ
The article deals with the use of horizontal band sawing machines for the production of lumber. The main problems associated with the use of this type of equipment are indicated. The reasons for the decline in the quality of sawn timber obtained when cutting logs on horizontal band saws are identified.Basing logs along the generatrix leads to a deviation of the butt end and a shift of the log axis from the horizontal plane from 30 to 70 mm, which causes an asymmetrical set, a decrease in volume output, an increase in fiber tilt and warping of the boards after drying. A method of calculating sawing schedules when cutting logs with regard to its basing is proposed.
Key words: Bandsaws, base of logs, inclination of fibers, warping of timber materials, cutting theory.
