An example of an exercise bar is provided. The exercise bar includes a first piece of wood having a first substantially flat surface with a first recess formed in the first substantially flat surface. The exercise bar also includes a second piece of wood having a second substantially flat surface. The second substantially flat surface is configured to mate with the first substantially flat surface and includes a second recess formed in the second substantially flat surface. The second recess is to align with the first recess. Furthermore, the exercise bar includes a weight disposed between the first piece of wood and the second piece of wood. A first portion of the weight fits in the first recess and a second portion of the weight fits in the second recess.

A movable conveyor 42 of a post-gluing conveyor 33 (sliding extendable roller conveyor) is provided, in a front portion, with a non-driving roller 42d (guiding roller) disposed so as to be inclined toward a reference surface (ruler) 42e at a predetermined angle with respect to a width direction such that a leading end of a veneer is guided toward the reference surface (ruler) 42e (one lateral side) of a movable conveyor 42. When the veneer is detected by a veneer detecting sensor 45 (veneer detecting means), a post-gluing conveyor controller 47 (slide movement control means) retracts the movable conveyor 42 in an extended state, in a contracting direction in a state in which forward rotational driving of a driving roller 42a of the movable conveyor 42 is maintained.

The invention provides a method for method for producing construction timber planks, construction timber and laminated planks or beams. The method includes the steps of sawing debarked and plantation dried logs from Eucalyptus trees having a moisture content of 18% or higher into planks having lengths suitable for the next step as described below. The planks are cross cut into lengths of about 0.5 m to 2.5 m and their end edges are profiled for finger jointing. The end edges of a series of profiled planks are joined by longitudinally pressing end edges together using a polyurethane glue to lengths required for construction timber planks.

A miter joint assembly system. The system comprises a generally planar assembly plate. A clamping assembly is attached to the assembly plate. At least one drill guide is detachably coupled to the assembly plate at a predetermined orientation. The clamping assembly is configured to releasably secure a first and a second mitered molding to the assembly plate such that the first and second mitered moldings are oriented generally orthogonally to each other. The drill guide is configured to bore a pocket hole and a pilot hole into the first mitered molding, the pocket and pilot holes receiving a fastener to draw and secure the second mitered molding to the first mitered molding.

An assembly and method is disclosed for providing an interlocking angular end joint. The interlocking angular end joint is capable of providing a virtually invisible end joint and comprises at least a first board capable of being longitudinally ripped from lumber to a predetermined width, at least a first angle cut at a predetermined angle into at least one end portion relative to the longitudinal length of the first board, and at least a first interlocking member capable of being machined into at least one end portion of the first board.

In known methods of preservative or upgrading heat treatment of wood, the starting material (2) is subjected to a selection process in order to select out wood with defects (6) (knots, cracks, resin ducts). A not inconsiderable part of the starting material is hereby not used to obtain thermally preserved wood. According to the invention the defects (6) are sawn out of the starting material, whereafter the remaining defect-free parts (14-1) are once again combined by finger jointing to form larger parts (16). The thus jointed wood structures (16) can be further assembled by lamination into even larger wood structures, the laminated wood structures (18). These can be applied particularly well as exterior cladding or as window or door frame in the building industry.

A lumber unscrambler and conveyor having first and second rigid units mounted at an incline on a support structure. Each unit has a plurality of spaced apart parallel plates in series along the incline and parallel thereto. The plates on the respective first and second units are interleaved in alternate relation. The plates have an upper article supporting surface and a leading edge generally transverse to the incline. The leading edge of plates proximate the in-feed end are of greater depth than those further along the path toward the out-feed end. The units are supported on the support structure to move relative thereto and one another. The units are driven in synchronized out of phase relation reciprocating along the inclined path. A hopper at the in-feed end receives and holds a supply of lumber pieces of selected dimension and as the plates reciprocate they move pieces of the lumber from the hopper to the out-feed end discharging normally only a single stick one after another.

The invention relates to a continuously operating device for directing pressing or pulling force at an object fed in relation to the device, at that part of the object which is at the location of the device, by using the at least two pairs of rolls or the like belonging to the device, which are at a distance from one another in the direction of movement of the object and through the nips between which the object is arranged to travel, whereby to at least one roll of at least one pair of rolls is connected, supported on the roll and thus rotating with the roll, an actuator effecting a rotary movement concentric with respect to the axis of rotation of the roll, the actuator being in turn arranged to transmit the rotary movement by mechanical power transmission means to at least one roll of the other pair of rolls. For supplying the driving power of the actuator is arranged a drive shaft which is arranged to rotate concentrically with respect to the axis of rotation of the roll, but independently with respect to the axis of rotation, and which drive shaft is, on the other hand, arranged to be rotated by a power means.

A system for defining and making wooden panels and similar items for furniture includes the following in sequence: a first station for loading an unworked piece of defined thickness (S.sub.h) onto a second station for cutting the unworked piece lengthways into two or more strip elements of equal width (LR.sub.hi); a third station for working the leading end and the trailing end of each strip element as it moves forward so that the strip elements can then be glued together end to end in sequence to form a continuous strip of strip elements and a fourth station where the continuous strip is cut crossways into a plurality of unworked panel strips whose length (LU.sub.hij) is defined by a sum of multiples of the panels needed to make a unit required or programmed.
