Abstract
This invention relates to a process and an apparatus for achieving cost-effective and loss-free chipping of lumber which is supplied in lengths of the customary transportation width of approximately 2.50 m. According to the invention, the process comprises a loading operation in which a feed compartment which opens into a chipping space is loaded from above with a compact, aligned lumber pile and then a feed thrust acts directly on the lumber pile to cyclically load it into a chipping unit. The cyclic feed of the lumber pile continues with pieces of lumber of equal length being loaded while a pile for the next load is formed into another compact, aligned lumber pile. An apparatus comprises a loading magazine with pivotable load flaps forming a V-shaped bottom and arranged above a trough and a thrust plate longitudinally displaceable in a controllable manner to thrust lumber into a chipping compartment.
