Claims
- 1. A method of producing cut timber from round logs in a manner to increase the cut timber yield by increasing the average useable diameter of the logs, comprising the steps of precutting all of the round logs to the same predetermined substantially constant length with the said length being within the range of between two to three meters, measuring the minimum useable diameter of each precut log, providing longitudinal guide surfaces on the periphery of the precut logs for establishing a guide surface relationship for each log in accordance with narrow useable diameter ranges of their minimum useable diameters, sorting the logs in accordance with their said measured minimum useable diameter and dividing them into a plurality of groups of logs having useable diameters within said narrow useable diameter ranges respectively and the same guide surface relationship, separately storing the groups of logs, presetting a timber cutting saw for each group of logs in accordance with its useable diameter range and guide surface relationship to provide a predetermined optimum timber yield for the respective guide surface relationship, and cutting the logs of each group of logs in succession with the timber saw into timber sections with the saw preset for that group of logs while guiding each log for cutting with its longitudinal guide surfaces to provide said optimum timber yield.
- 2. A method of producing cut timber from round logs in a manner to increase the cut timber yield by increasing the average useable diameter of the logs, comprising the steps of precutting all of the round logs to the same predetermined substantially constant length with the said length being within the range of between two to three meters, measuring the minimum useable diameter of each precut log, providing longitudinal guide surfaces on the periphery of the precut logs for establishing a guide surface relationship for each log in accordance with narrow useable diameter ranges of their minimum useable diameters to provide the same guide surface relationship for all of the logs within each said narrow useable diameter range, sorting the precut logs in accordance with their said measured minimum useable diameter and dividing them into a plurality of groups of logs having useable diameters within said narrow useable diameter ranges respectively, separately storing the groups of logs, presetting a timber cutting saw for each group of logs in accordance with its useable diameter range and guide surface relationship to provide a predetermined optimum timber yield for the respective guide surface relationship, and cutting the logs of each group of logs in succession with the timber saw into timber sections with the saw preset for that group of logs while guiding each log for cutting with its longitudinal guide surfaces to provide said optimum timber yield.
