… working daily with wood measurement, in order to get a valid evaluation of the logs. Eight sites were included in the survey, and on each site 50 logs were marked. Approximately one third of the marked logs were pulpwood, and the remaining logs marked were timber. The sites had …
utvärdering av analysprogrammet Stockholmen för automatiserad timmersortering i dimensions- och kvalitetsklasser hos BARO WOOD AB
… made at BARO WOOD AB today, analyse differences in center board quality from logs with a good quality and logs with a bad quality, suggest new sorting criterias developed from analyses made with Stockholmen and to evaluate the program Stockholmen. All analyses are based on data …
… work towards decreasing the frequency of bucking splits in their saw timber logs. SCA Forest supplies the Munksund sawmill with pine timber. Periodically the sawmill experiences problems related to bucking splits in their logs. The purpose of this study was to find an available …
… the sawn yield, for sawmills with straight-sawing. It is desirable that these logs could be sorted based on more criteria, if it increases value-yield and consequently the utilization of raw-material. Bow-heights over 1 cm have a negative effect on sawn yield, since the surface …
… in production and data was received from different drivers. Totally 1680 logs were checked, half butt logs and half middle logs. The result showed that 3,8 % of the butt logs, and 6,8 % of the middle logs had bucking splits. The average length of the splits were 10,2 centimeters …
… enduse orientated quality grading of Scots Pine (Pinus sylvestris) saw logs by using a gamma-ray log scanner. Iggesund Timber AB has the possibility to grade logs automatically with TINA, a two way gamma-ray log scanner. Grading and classification of Scots Pine logs in Sweden …
… be used I field. Under the field-study data were collected from 570 saw timber logs, 30 logs from each one of the tested harvesters. Logs of log-types middle- and topplogs of pine and spruce was cheched and were a part of the study. 56 percent of the logs were pinelogs and 44 …
The measuring of logs is important in the sawmills process to the sawn products. The technology of automatic wood measurement is continuance developing. This study has the purpose to see how the different techniques and the routines works of measure frames for determining of …
… was performed in the reserve. In some places where coarse dry woody debris (logs and stumps) was present, the fire consumed the wood, as well as parts of the humus layer, creating deep-burned patches. The low intensity ground fire also created dead woody debris by burning off …
… During year 2000, Hallstavik used approximate 1.200 m3f spruce, either as logs or chips from sawmills. Due to that the production is running continuously the mill also needs raw material at the same rate. At some periods the supply of raw material cannot keep up pace. Especially …

… thinnings is the "long top method? (LT-method). With this method saw logs and non-delimbed tops are recovered, i.e. no pulpwood is recovered. Branches from delimbed sawlogs are not recovered and only long top (with branches and needles still attached) is hauled the landing site …
The aim of this thesis is to find a statistical model that sort logs according to a predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable …
… close to Uppsala in Sweden, which is a spruce dominated forest. In 1995 logs with dense populations of C. chrysomelinus were translocated into two locations within this reserve. Circular study plots were established with a radius of 75 m around the translocated logs in both …
preparing for the unpredictable
… cases working with reduced efficiency was preferred over losing the quality of logs. The main cause for the loss of efficiency is increased harvesting expenses from working with storm-felled logs, increased storage costs, and slightly increased costs from hiring external …
