Definitions
- the present invention relates to a means for sawing elongate units from a tree-trunk.
- These units may be substantially rectangular in cross section. It is known to join two elongate units by means of a glueing process to form a single product for use as studs, for instance. Such units have previously been produced from a dried trunk, with the
- the object of the present invention is to avoid such changes in appearance. According to the invention this is achieved by means of an installation having a number of stations where in a first station a damp trunk is sawn up into lengths and the lengths are then split
- 1- agent has been selected in which the glueing process is only completed when the stack clamped together is in the sixth station.
- the speed of transport from the glueing station to the drying station is so selected that said glueing process is only completed in the drying station.
- the glue chosen shall have such properties that the glueing process does not terminate until the glue is in the drying station.
- the glue is thus dependent on the transport time from glueing station to drying station.
- the glue is also dependent on moisture deprivation in the drying station.
- Figure 1 shows a block diagram of the installation
- Figure 2 shows the appearance of the timber in the various treating stations
- Figure 3 illustrates a plan of how the various machines are arranged.
- An untreated tree-trunk having a moisture content of approximately 30 % is supplied to a saw 1.
- the stock is shown in Figure 2 where it is designated 0.
- a first station 1 the trunk is sawn into lengths designated la.
- the trunk is thereafter supplied to a station 2 and there sawn in such a manner that the lengths produced in station 1 are split lengthwise.
- the split lengths are designated 2a.
- the saw in station 1 may be a circular saw or a band saw.
- the saw in station 2 may be of the same type as that in station 1.
- the trunk is illustrated at 2a after two sawing processes.
- the sawn trunk designated 2a is composed of a number of similar units, two or more of which are joined together, glueing being performed first in station 3.
- a polyurethane type of glue is used for the purpose.
- the units to be glued are designated 3a.
- the units may also be turned in said glueing station so that the annual rings in the two units to be joined face away from each other.
- the glue is applied by spraying.
- the units glued together are supplied to a fourth station 4 functioning as a stacking station. In this station a number of layers of glued units are stacked one on top of the other. The procedure in the fourth station 4 is carried out in conventional manner. A stack is illustrated and designated 4a.
- a stack is conveyed to a fifth station 5 where it is clamped together both from above and from the side.
- a stack is bandaged so that the compressed shape of the stack is retained.
- the bandaged stack is designated 5a.
- the bandaged stack is supplied to a drying station 6.
- the drying station may be of the type described on page 91 of "General sawmill techniques" issued by the Employers 1 Federation of Swedish Forest Industries.
- the temperature in the drying station is over 60°. Drying should continue until a moisture content of approximately 10 % has been reached.
- a stack is bandaged the units in the stack are extremely flexible and can therefore be shaped to the correct shape. This correct shape is retained thanks to the bandaging.
- the glued units cannot become deformed during the drying process, and when they leave station 6, therefore, they are the correct shape without any sign of distortion, as is illustrated at 6a.
- Figure 3 shows the purely practical arrangement of a means according to the present invention.
- the designations used in the following description are independent of those used in the preceding figures.
- 1 is a unit to receive timber.
- Said timber is conveyed to a debarker 3 by means of a supply conveyor 2.
- the debarker 3 cooperates with a feed-out conveyor 4 which carries the debarked timber to a transverse conveyor 5.
- Timber from said conveyor is supplied to a feed-in conveyor 6 which feeds the timber to a sawing machine 7.
- the sawing machine 7 cooperates with a feed-out conveyor 8 which supplies the timber to a sorter 9. From the sorter the timber is carried to a splitting machine 11.
- Split timber is then supplied by a conveyor 12 to a glue- supplying unit 14.
- the glued products are supplied by a conveyor 13 to a stacking device 16.
- the stacked timber is supplied to a sorting means 17.
- Stacked timber is compressed in a unit 18 and also bandaged.
- the bandaged timber is supplied to an elevator 19 and from there to one of the conveyors 20 and 21, both of which cany the bandaged timber to a dryer 22.
- a supply conveyor 10 is shown in the figure which can either supply timber which has not yet been debarked from unit 1 to the dryer 22 or supply dried timber from the dryer 22 to the unit 1.
