Abstract
An improved separator for separating lumber in a stack of a plurality of layers has a primary profile for minimizing the contact area and maximizing airflow between the separator and the adjacent boards and a secondary profile for improving frictional resistance between the separator and the adjacent boards. The primary profile comprises a plurality of grooves and a plurality of ridges formed therebetween. The secondary profile comprises a plurality of depressions on the ridges.

An improved separator for separating lumber in a stack of a plurality of layers, the separator comprising a length, a height, a width, opposing sides, a plurality of grooves extending transversely to the length, and a plurality of ridges formed between the grooves, wherein each ridge has a length, a height, a peak, and a plurality of depressions formed on the peak extending transversely to the length of the ridge.
An improved separator for separating lumber in a stack of a plurality of layers, the separator comprising a length, a height, a width, a primary profile, and a secondary profile, wherein:
- the primary profile consists of a plurality of grooves extending transversely to the length and a plurality of ridges formed between the grooves, wherein each ridge has a length, a height, a peak, and
- the secondary profile consists of a plurality of depressions formed on the peaks and extending transversely to the length of the ridges.
A method for producing a secondary profile on a separator, comprising the steps of:
- providing a separator comprising a length, a height, a width, and a primary profile, consisting of a plurality of grooves extending transversely to the length and a plurality of ridges formed between the grooves, wherein each ridge has a length, a height, and a peak, and
- pressing a moulding roller over the peaks of the ridges to thereby create a plurality of depressions thereon extending transversely to the length of the ridges.
