I~ferring now to Fig. 1 the present device comprises a spindle 1 mounted on a holding plate 2. Spindle 1 incorporates within a conv~ntion-q-l electrical rotor assembly (not shown). A bit or a cutter means 11 of a spindle 1 extends through a first guiding means or template 3. This 10 template 3 is mounted on the holding plate 2 and is provided with an inner perim~ter to guide bit 11 during the steps of forming left and right miter lines dçfining the inside corners of a frame 12 supported on a support frame 13. One part of said iMner p~rimet~r of the template 3 (see Fig. 4) comprises an isosceles triangle havind two sides meet at a 90 degrees angle to each other, said sides are oriented to be substqnti~lly parallel to left and right miter lines of the frame 12 15 respectively. The holding plate 2 is slidably mounted by means of set of bearings 4 and 5 on a sliding cylinders 7 and 6 respectively, which in turn are mounted on the support frame 13. Those sliding cylinders 6 and 7 in combination with bearings 4 and 5 represent second guiding means adapted to guide the movement of spindle 1 alongside the frame 12 to form the remqin(ler of groove portions located between miter lines d~finin~; an inside corners. It is very important to 20 place the frame 12 under the predet~rmined angle in the relation to horizontal surface for forming a groove of desired shape on the face portion ofthe panel or frame 12. Referring to Fig. 2, the frame 12 is releasably mounted on the supporting frame 13 by means of supporting plate 8 provided with ret~inin~ grips 9. Said ret~inin3~ grip 9 has a spring biased me~ h~ni~m 18 mounted between the movable portion of said ret~inin~ grip 9A and an abutting wall 10 for releasably retain the frame 12. Depending on the size it is possible to mount a number of frames to be processed in one step. The supporting plate 8 may be adjusted to any desired angle by means of gradated disk plates 14 provided with a corresponding circular slot and pressure knob 19, thus allowing to form grooves in the frame 12 of any desired angle. The bit 11 is also interchangeable which allows to form a groove of any desired configuration. As it clearly shown on Figs 1 and 2, template 3 is provided with a stop means or stopper 15 pivotally mounted on the upper surface ofthe holding plate 2 by means of pivotal arm 16 mounted on a stop support 17. The stopper 15 is extPnlling through the opening in the holding plate 2 and is provided to restrict the movement of cutter bit 11 beyond predetermi1led area ofthe frame 12 design~ted for formation of miter lines defining left and right inside corners. Tn the absence of such stopper, the bit 11 may go beyond the de~ign~ted area and spoil the desired configuration ofthe groove. Tn case there are more than one frame to be treated, the stopper 15 may be m~ml~lly retracted to allow to move the cutting assembly to the next frame.
Tn operation the frame 12 is preli~ .ary machined by any conventional means to remove a central portion thus forming a one-piece frame PlemPnt Further said frame 12 is positioned onto supporting plate 8 mounted under predetermined angle in the relation to plane surface. Ret~ining grip 9 provided with spring biased mech~ni.cm 18 allows to releasably hold said frame 12. Then holding plate 2 is moved on top ofthe frame 12 and spindle 1 is first positioned at the 90 degrees corner of the triange identif~ing the apex of template 3 . While moving along the left side of said triangle portion oftemplate 3, the bit 11 is shearing a miter line defining the left inside corner of frame 12. The stopper 15, ext~nllin~ through the holding plate 2, prevents the bit 11 from moving beyond the dçci~ted area. A~er the left miter line is formed, the cutter assembly including spindle 1 and holding plate 2 are slidably moving alongside the frame 12 to shear the rem~inder of groove portion located between left and right miter lines. When the cutter assembly reach the right corner, bit 11 will move along the left side of said triangle portion of template 3 to form the miter line definin~ the right inside corner of the frame 12. As in a previous step, the stopper 15 will restrict the movement of the bit 1 lwithin the desi~ted area. The steps of forming both left and right inside corners and the groove ext~n~ling between those corners is continuous. Similar steps are taken to shear grooves on all other sides of frame 12. It is also possible to treat ~iml~lt~neously a number of frames supported on said supporting plate 8 depending on their dimensions. In this case the stopper 15 should be retracted m~ml~lly during switching from one frame to the other.
The finished product, illustrated on Figs 5 and 6 is a one-piece el~m.ont having a continuous groove of predetermined configuration. Suggested n~qteri~l~ to be used are: wood, presswood, fibre, plastic, etc.
Figures 7 and 8 represent a second modification ofthe present embodiment specially designed for m~mlf~cturing of large size frames. This arrangement additionally comprises vertical eillrolcement bars 20 ext~ in~ from both sides of the support frame 13. Those bars 20 are connected by means oftransverse bar 21, which in turn is re;~olced by means of angled support bar 22 and vertical central rod 23 provided with a tension nut 28. Holding plate 2 is additionally provided with vertically oriented plate guiding element 24 having an inverted U-shaped configuration. Figure 8 shows that transverse bar 21 in the cross-section has an inverted T-shaped configuration, which allows to gl~ in~ly move holding plate 2 by means of respective guiding rollers 25 and 26 mounted on said plate guiding element 24.
The new machine and method provides the following advantages with the known systems:
in the present invention it is possible to use pine fibre which is light in weight, less expensive and allows to manufacture a one-piece frame. In the same time known systems use wood "hner"
which is heavy in weight, more expensive by the foot and consists of four pieces which have to be cut in order to make one frame. Besides, each of those four pieces has to be cut individually;
the process according to the present invention is less time con~lming in comparison with known processes, wherein it is necessary to cut ffiur separate pieces, bevel them separately and then glue together and sand every corner;
the present invention produces a long lasting product, since it is not cut in corners, wood is more rigid and therefore keeps its initial form; cracks do not appear in the corners under the liner as it happens in known products, thus keeping the appearance for many years;
one ofthe most important advantages is the fact that the present machine allows to use pine fibre, which is recycled product which in turn may be further recycled.
Although the invention has been herein shown and described in what is conceived to be the most practical and prt;relled embo-lim~nt~, it is recognized that depallul~s may be made therefrom within the scope of the invention, which is not to be limited to the details disclosed herein, but is 20 to be accorded the filll scope ofthe clairns, so as to embrace any and all equivalent devices and apparatus.
