Paavo Aro. (1954). On the reasons for differences in the measurements of exported pulpwood. Acta Forestalia Fennica vol. 61 no. 7 article id 7419.
Keywords: pulpwood; measurement; export; paper wood
Abstract | View details | Full text in PDF | Author Info

Exported wood is measured at the port in Finland by certified measurers. Wood is paid according to these measuring certificates. However, in many cases the buyer measures the wood again in the country of destination, and gets smaller amounts. This sometimes causes awkward situations.

To examine the phenomenon one lot of pulpwood was measured both in Finland and in the destination country Germany. Several differences were found for the amounts of wood, and the author discussed the possible reasons for these differences.

However, because of the possible scattering in the measurements, several reductions are always made to the measurements. Hence it was proved that the buyer got the amount of wood they paid for. It is clear that the current practices and tools used to measure the amount of wood do not allow for any more accurate measures.

Repairing of a saw after work is described in detail. The seven phases of the work are: fastening and tightening the saw to the frame, evening the row of the saw tooth, determining the depth of the gullet area, sharpening the teeth, setting of the saw, and check-up of the repair.

Original keywords: aikatutkimus; katkonta; sahanterät; halkosaha
English keywords: time study; cross-cutting; saw blades; wooden bow saw; bow saw
Abstract | View details | Full text in PDF | Author Info

Effectiveness of 18 different saw blades of wooden bow saw from four producers (Oy Suomen Sandvik Sahat, Epilä Oy, Ab Orsa Sågbladsfabrik Oy, Kone ja Terä Oy) was tested in 1937. The experiments were divided into test series according to type of maintenance of the blade and tree species (Scots pine, Norway spruce and birch) to be sawn. Each saw blade was sharpened into four different sharpening angles (54°, 60°, 64°, 70°). Four blades had markedly longer sawing times compared to the others. These blades had a special serration. In addition, two blades with sparse serration had slightly poorer results than the blades in general. When the tree species were compared, birch (Betula sp.) was slowest to saw followed by Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.).

Abstract | View details | Full text in PDF | Author Info

A psychological and technical test was planned for selecting students to Forestry School of Tuomarniemi in Finland. This was the first attempt to use psychological and technological tests to choose forest professionals in the country. The entrance examination of the forestry school included tests for knowledge about forest work, estimation of distance and dimensions of a tree, dexterity and memory. The article suggests that similar test should be generally used in forestry.
