Description

Device for cutting laminate floorboards

The invention relates to a device for cutting a porous, substantially rigid plate, in particular laminate floorboard with a frame, a support formed by the frame support for the plate, a support associated with the immersion slot and on the frame about a pivot bearing pivot axis formed such fixed cutting knife, that its cutting edge when pivoting the cutting blade from an open position into a closed position immersed in the immersion slot, wherein a lying in the pivot plane intersection between support and cutting edge during the closing of the cutting blade from the pivot bearing proximal side of the support towards the migrates to the pivot bearing distal side of the pad.

Such a cutting device is known from FR 575749. FR 612747 A and FR 847014 A also describe such cutting devices.

The invention has for its object to further develop the generic cutting device nutzsvorteilhaft.

The object is achieved by the invention specified in the claims, wherein not only the independent claims, but also the dependent claims each represent advantageous developments of the prior art.

A first development of a generic laminate cutter relates to a hold-down. If a laminate slab to be sliced is divided stepwise by incomplete individual slices, then the slicing knife must be swung back after each individual slit through the generated slit gap. The flanks of the kerf however adhere frictionally to the broadside surfaces of the cutting blade, so that there is a tendency to raise when opening the cutting blade from the closed position to be cut plate. This, deemed disadvantageous lifting is prevented by the hold-down invention. The latter acts on the upper side of the plate in the direction of the support when the cutting blade is pivoted from its closed position into the open position. Preferably, the hold-down is formed by a lever arrangement. The lever arrangement may be associated with the cutting blade. For this purpose, a two-armed actuating lever is preferably articulated on the cutting blade. The actuating lever has a hold-down, the end in the course of the opening movement of the

Cutting knife applied to the plate to be cut from above. This is preferably done with the free end of the low halterarms. The second arm of the actuating lever forms a handle arm, at the end of a handle is attached. With the handle, the cutting blade can be pivoted about the pivot axis. The pivot bearing, with which the actuating lever is attached to the cutting blade, may be formed by a screw. In a preferred embodiment, the actuating lever is formed by two identically shaped metal, in particular steel plates, which receive the cutting blade between them. It is provided a stop limit, with which the pivot angle of the actuating lever is limited relative to the cutting blade. For this purpose, a stop pin connecting the two steel plates with one another can pass through an arc slot of the cutting blade. Furthermore, a locking device is provided with which the pivoting of the actuating lever relative to the cutting blade can be blocked. The lock preferably consists of a knob which is screwed onto a threaded pin. In the blocking position, the threaded pin lies in an open-edged slot of the cutting blade. By tightening the knob, the two steel plates forming the operating lever are pressed against the broad sides of the cutting blade. A second development of a generic laminate cutter relates to the design of the cutting blade. It is envisaged that the cutting blade has a cross-section-reduced zone extending between the breast and the back of the cutting blade, which runs parallel to the support in the open position of the cutting blade. This reduced cross-section zone thus extends in a straight line between the cutting edge forming the breast and the back pointing away from the cutting edge. This cross-section reduced zone has two parallel or acute-angled edges. In the open position of the cutting blade, the lower edge of the cross-section reduced zone runs below the support. The upper edge of the cross-section reduced zone runs above the support. The upper edge is spaced far enough from the support so that it extends above the surface of the plate to be cut. Preferably, the cross-section reduced zone is formed by two groove-like depressions, which are incorporated in the two opposite broad sides of the cutting blade. The edges of the cross-section reduced zone are formed by steps or curves. It can also be a fluid transition here. These reduced cross-sectional areas prove to be advantageous if a wide laminate slab is to be cut with the laminate slicer in several successive slices. After the first cut, the cutting knife is brought into the open position. The part cut produced in this first cut has a width which is greater than the material thickness of the cutting blade in the area of the cross-section reduced zone. In the open position, this cross-section reduced zone runs directly above the support, so that the laminate plate can be pushed relatively smoothly relative to the cutting blade. Alternatively, the cutting blade can be moved relative to the frame in the manner already described above. In this case, the cross-section reduced zone moves through the cut into the laminate slab part. A third development of a generic laminate cutter relates to a support block. The support frame is temporarily attached to the frame. The attachment can be done via a snap or clip connection. The support block is preferably an arcuate part which is placed on the frame formed by two hollow bodies. In this case, a head portion of the support bracket is above the support of the frame. Two foot sections each form a lower peripheral edge with which the support bracket can be placed on a base. Between the foot portion and the head portion extends a central portion. The latter has one

Cross-section contour line that follows the outer wall of the frame. The height of the support bracket corresponds to the height of the frame. The support bracket can be placed at a distance from the frame to the ground. His head surface is then spaced about the same amount from the ground as the support of the frame. The support bracket serves to rest a plate to be cut.

A fourth development of the prior art provides that the pivot bearing, with which the cutting blade is attached to the frame, can be displaced in the extension direction of the immersion slot, ie in the cutting direction. According to this embodiment, by using a stop, a laminate plate wider than the effective cutting length of the cutting blade can be cut. The cut can be carried out in several successive steps, whereby the laminate plate can remain in the stop position in its contact position. It is not the laminate plate relative to the frame, but the cutting blade relative to the frame displaced. In a further development of the invention, a locking mechanism is provided which blocks the displaceability of the pivot bearing when the cutting blade has been pivoted by a predetermined pivot angle from the open position in the direction of the closed position. In the open position is the cutting knife preferably pivoted about 90 ° relative to the support. In this open position, the pivot bearing can be displaced in the extension direction of the immersion slot, ie in the cutting direction. As soon as the cutting blade is displaced by a certain angle from this fully open position towards the closed position, ie at the beginning of the cut, the locking mechanism comes into effect. The latter preferably has an eccentric cam. This eccentric cam is rotatably connected to the cutting blade. It thus rotates when the cutting blade is pivoted. The eccentric cam forms a radial board, which cooperates with a terminal block. He moves the terminal block against a supporting flank of the frame, so that the terminal strip applies friction there. This creates a braking force that blocks the displaceability of the pivot bearing relative to the frame. The eccentric cam is part of a pivot axis with which the cutting blade is mounted in bearing supports. The bearing carriers preferably form a bearing guide. The latter can be formed by two link elements. The bearing block is preferably guided linearly on guide ribs. The guide ribs may protrude from two spaced-apart opposite guide walls and have a dovetail contour. These dovetail webs engage in dovetail grooves of the bearing block. The two sliding shells can be formed by plastic injection molded parts. These can form a pocket in which the terminal strip is located.

A development of the generic state of the art relates to the design of the cutting edge of the cutting blade. The latter has spaced-apart teeth, which dig when closing the cutting blade successively in such a way in the surface of the plate to be cut, that the plate is displaced during cutting only slightly in the cutting direction. As a result of such a configuration, it is possible to dispense with the use of a stop when an endless cut is to be carried out. The teeth preferably have two flanks meeting in a vertex. The flanks of adjacent teeth are spaced apart by straight and slightly curved portions of the cutting edge. The flanks pointing with their flank surface to the axis of rotation have a steeper angle of attack than the flanks facing away from the pivot axis with their flank surface.

According to a fifth development of the prior art teeth are provided in the region of the support. These teeth serve to support the workpiece on the support and are capable of digging into the back of the workpiece when pressure is applied to the workpiece from above. To avoid a risk of injury in the open position of the cutting blade is proposed that the teeth change during pivoting of the cutting blade from the open position in the direction of the closed position of a hidden position in a leading position. It can be provided that the teeth move during pivoting of the cutting blade in the open position in a recessed position. As soon as the cutting blade is displaced from the open position in the direction of the closed position, the teeth change from the hidden position to the initial position. The teeth are preferably assigned to a toothed strip. This rack is inserted in a receiving groove which extends parallel to the immersion slot. On both sides of the immersion slot such receiving grooves can be provided, which are each equipped with a rack. The toothed racks can be raised and lowered. In a further development it is provided that the teeth, which may also be formed by a rack, sit firmly on the frame. The teeth also run in rows parallel to the immersion slot. There is a bar next to the teeth. The surface of the strip having a substantially rectangular cross-section forms the support for the plate to be cut. In an unloaded state, the imaginary plane, in which the top of the strip lies, overhangs the tips of the teeth. The top of the bar can be displaced in the downward direction by applying a pressure. the. For this purpose, the strip may be formed from a compressible, in particular rubber-elastic material, for example foam rubber. The downward displacement of the top of the bar is done for example by supporting the plate to be cut or by exercising the cutting force. The upper side moves downwards under the tips of the teeth so that the teeth of the row of teeth can dig into the underside of the plate. A row of teeth and a strip extend in each case on both sides of the immersion slot, the two rows of teeth extending between the two strips extending parallel to one another.

A sixth development of a generic laminate cutter concerns the design of the frame. The latter is preferably formed by one or more hollow bodies. Preferably, the frame has two substantially identically shaped, mirror-symmetrically arranged hollow body. The hollow bodies are preferably aluminum extruded parts. The two ends of the hollow body are preferably connected to front side panels. These face panels can also form the feet of the cutting device. The front panels hold the two hollow bodies at such a distance from one another that the immersion slot is formed between them. In addition, the two hollow bodies also form the two above-mentioned, mutually spaced guide walls on which the bearing guide is guided.

In a further development of a genus in contemporary laminate cutter is provided that the remote from the bearing axis end of the cutting edge forms a last tooth. Its tooth flank pointing away from the pivot axis essentially crosses the support at right angles when the cutting blade is closed. As a result, this last tooth produces a substantially perpendicular to the cutting direction extending end edge in section. This last tooth is adjacent to a stop buffer. A seventh development of a generic laminate cutter relates to the stop. This is fastened with a fastening screw above the support, whereby the fastening screw protrudes through the immersion slot and is screwed into a tensioning slide. The clamping slide is supported below the support in the area between the two hollow bodies, which form the frame, on stiffening webs. Friction-enhancing elements are provided with which the tensioning guide is supported on the stiffening ribs. In addition, detent webs protrude from the tensioning scenery. These grip through the immersion slot and in a recess of the stop to fix it in a 90 ° position. Several detent recesses may be provided in order to fix the stop in a 45 ° position or, for example, in a 30 ° or 60 ° position.

Fig. 28 is a perspective view of the laminate cutter of FIG. 27 with the end cap removed and

29 shows the laminate cutter according to FIG. 27 with the support block 71 in the functional position.

The frame 2 of the laminate cutter is formed by two substantially mirror-symmetrically arranged hollow bodies, which are manufactured in the aluminum extrusion process. The two hollow bodies each have a bottom denwand 46, an outer wall 43, an inner wall 44 extending parallel to the outer wall and a guide wall 45 extending between outer wall 43 and inner wall 44. While the guide wall 45 extends substantially in the vertical direction, the bottom wall 46 extends substantially horizontally.

The two housing halves are spaced apart. The distance between the two housing halves defines a slot 4. The slot extends between two web extensions 55, which each form Abstützflanken 18. At the two ends of the supporting flanks 18 directed towards one another there are stiffening webs 19, which form an upwardly open pocket.

Towards the top, the web extensions 55 form a support 3 for a laminate plate 1. In each of the two pockets extending parallel to the immersion slit 4, racks 20 are located. There may be provided an unillustrated mechanism to shift these toothed racks 20 in the vertical direction.

In the embodiments shown in the drawings, however, the toothed racks 20 are stuck in the grooves 50. In addition to the two on each side of the slot 4 extending toothed racks 20 lie in recesses 56 of the web extensions 55 foam rubber strips 53 a. The upwardly facing surfaces of the foam rubber strips 53 lie in a common plane E, which extends above the tips 52 of the teeth 51 of the toothed bar 20. The strips 53 can be compressed. This is done by a vertical pressure from above. In the unloaded state, the plane E of the tops of the strips 53 extends over the tooth tips 52, so that a risk of injury is minimized. If, as shown in FIG. 20, a laminate plate 1 is placed on the upper side of the strips 53 and a vertical pressure is exerted downward on the latter, the upper side of the strips 53 displaces according to a compression The latter is down. The tips 52 of the teeth 51 can dig into the underside of the plate 1 to be cut.

If a cutting blade 6 hinged to the frame 2 is in the completely open position shown in FIG. 1, the teeth of the toothed strip 20 are in a position of concealment. They are in a retracted position relative to the top 3 of the strips 53 forming the support. If the cutting blade 6 is displaced clockwise from the open position shown in FIG. 1 in the direction of the closed position, the point of intersection 8 between cutting edge 7 and support 3 shifts towards a stop 22, the toothed racks 20 come out of the recessed position. You can thus dig into the bottom of the laminate plate to fix it.

The two housing halves are fixed to each other by means of end covers 40, which may be made of plastic. These face panels also form the feet with which the frame 2 can be placed on a level surface. They protrude beyond the bottom wall 46. In the area of the corner between the bottom wall 46 and inner wall 44 is a guide slot 47. The two opposite guide slots 47 of the two housing halves form a guide for a designed as a plate drawer 39. With this drawer 39, the gap between the two housing halves can be closed. This space forms a Spansammeikammer. A bottom plate of the drawer 39 is seated on an end plate 42, which lies in a recess 41 of the front panels when the drawer is closed. There are two drawers 39 are provided, which can be inserted from the opposite ends.

The cutting blade 6 has at its bearing end a bearing opening and at its other end a handle. A marginal edge of the cutting blade 6, which adjoins the bearing end directly, forms a cutting edge 7. The opposite edge forms the back of the cutting blade 6 and is substantially rectilinear. The cutting edge 7 extends in such an arc shape that, when the cutting blade 6 closes, the point of intersection 8 between the support 3 and the cutting edge 7 moves away from the pivot bearing of the cutting blade 6. The arcuate cutting edge 7 has a multiplicity of spaced-apart teeth 17. The flanks 17 "of the teeth 17 facing the pivot bearing axis 5 have a steeper angle to the contour line of the cutting edge 7 than the tooth flanks 17 'facing away from the pivot bearing Teeth 17 when closing the cutting blade 6 successively in the surface of the laminate plate 1, so as to reduce slippage of the laminate plate 1 during the cut.

With the laminate cutter laminate plates can be cut, which are wider than the length of the cutting edge 7. Such a laminate plate 1 is placed with a peripheral edge against a contact edge of the angle stopper 22, wherein the angle stopper 22 has a greater spacing from the pivot bearing axis 5, as the length of the Cutting edge 7. In a first section, starting from the position of the cutting blade 6 shown in FIG. 1, a first partial section is produced. The cutting blade 6 is located there at the maximum distance from the angle stop 22. The cutting blade 6 can be displaced in the direction shown in Fig. 1, fully open position in the direction of the angle stop 22. For this purpose, the user can attack on a handle 21 attached to the back of the cutting blade 6.

The subsequent cut can then take place from the operating position shown in FIG. 2, in which the cutting blade 6 is mounted closer to the stop 22.

To enable the above-described operation, the pivot bearing axis 5 is supported by a bearing slot 9, along the guide walls 45 can be moved in the cutting direction. The pivot bearing axis 5 consists of two bearing halves, which are connected to one another the bearing eye of the cutting blade 6 by cross-connecting screw 13. The two axially facing away from each other end portions of the pivot bearing axis 5 form eccentric 12 of. A first section 12 'consists of a tangential surface. A circular cylinder jacket surface 12 "adjoins this secant surface 12 '. The circular cylinder jacket surface 12" is mounted in a bearing opening 14 of a slide shell 9 of the bearing guide. The eccentric 12 also has a stop 12 '".

The guide shells 9 each store one of the two mutually path-pointing eccentric sections 12 and form, following the bearing opening 14, respectively pockets 10, in each of which a clamping strip 11 rests. The guide shells 9 also form dovetail grooves 16, engage in the dovetail webs 15. The dovetail webs 15 run on the outer sides of the guide walls 45, thus face each other and extend parallel to the immersion slot 4. The clamping strips 11 rest on one side on the eccentric portion 12 of the pivot bearing axis 5. On the other side, the terminal strips 11 bear against the supporting flanks 18.

In the open position of the cutting blade 6 shown in FIG. 7, the flank 12 'of the eccentric section 12 running on a secant lies in the bottom plane of the pocket 10, so that the clamping strip 11 is not pressed against the supporting flank 18.

In this operating state, the stop 12 '"is located on a counter stop of the guide shell 9. The bearing guide 9 can thus be displaced in the extension direction of the immersion slot 4. It slides along the dovetail webs 15. If the cutting blade 6 is pivoted in the direction of its closed position, the clamping strip 11 is acted upon by the peripheral section 12 ".The clamping strip 11 then presses against the supporting flank 18, so that the loadability of the bearing guide 19 is frictionally locked.

The angle stop 22 rests on the support 3 and has an opening 30 through which a screw 23 is inserted. The opening 30 is closed with a plug 31 which overhangs the head of the screw 23. The threaded shank of the screw 23 is screwed into a threaded opening 27 of a clamping slide 24. The clamping slide 24 is located in the intermediate space between the two guide walls 45. It has two projecting into the immersion slot 4 locking webs 28, which may protrude beyond the support 3. The clamping slide 24 also has two mutually parallel grooves 26 in which threaded pins 25 einliegen as reibschlussvergrößernde elements. When tightening the screw 23, the jacket walls, so the threads of the rib body 25, pressed against the stiffening webs 19. Thus, there is a frictional securing the angle stop 22 against displacement.

If very wide plates are to be cut, ie those whose width exceeds the length of the frame 2, the angle stop 22 can be removed by loosening the screw 23. For captive mounting of the clamping slide 24 in the distance space between the two guide walls 45, protrude from the underside of the clamping slide 24 each terminal tongues 29, which can be supported on the dovetail bars 15.

In a 90 ° - or 45 ° - angular position of the angle stop 22 engages a latching web 28 in a latching niche 34 of the angle stop 22 a. To adjust the angle stopper 22 in a different angular position, the screw 23 is released. The device has optional stiffening means. These consist of two mutually parallel steel rails 36, which are arranged below the support flank 18 and which limit the displacement of the bearing block 9. The stiffening rails 36 are fastened with a plurality of fastening blocks 37 in the intermediate space between the guide walls 45. The dovetail webs 15 serve for fastening purposes. For stabilization, two reinforcing rails 36 arranged on different sides of the immersion slit 4 are connected to one another by means of connecting webs 38. The connecting webs 38 each connect two Halteböckchen 37 with each other.

The last tooth 48 already mentioned above forms the cut-end end of the cutting edge 7. This last tooth 48 is adjoined by a stop buffer 49 which is located at the grip end of the cutting blade 6.

The embodiment shown in Figures 21 and 22 substantially corresponds to the embodiment described above, but here on the end plate 42, a foot 57 is provided. The embodiment of the cutting blade 6 is essential in this embodiment. While in the embodiment described above, the handle is seated on an arm of the cutting blade which is formed integrally with the actual blade, in this exemplary embodiment the grip arm 59 is formed by an arm of a two-armed actuating lever 58. At the end of the handle arm 59 of the handle 62 is placed. It consists of two handles.

The operating lever 58 consists of two substantially identically shaped steel plates which receive the steel cutting blade 6 between them. The two steel plates forming the actuating lever 58 are connected to one another by a hinge axis 61. The hinge axis 61 extends through a joint bore of the cutting blade 6. The actuating lever 58 can be pivoted relative to the cutting blade 6 about this hinge axis 61 become. To limit the pivot angle of the actuating lever 58 relative to the cutting blade 6 stop means are provided. These consist of a stop pin 65 which passes through an arcuate slot 66 of the cutting blade 6. The two ends of the arcuate slot 66 limit the pivoting angle of the actuating lever 58.

The second arm 60 of the actuating lever 58 extends approximately at a 180 ° angle to the first arm 59. Both arms 60, 59 are approximately equal in length. The free end 60 'of the second arm 60 is capable of exerting a hold-down function for a plate 1 to be cut. Accordingly, the second arm of the operating lever 58 forms a hold-down arm 60. The pivoting angle of the actuating lever 58 and the length of the hold-down arm 60 are so focused on the position of the axis of rotation 61 that when opening the cutting blade 6 from a closed position toward an open position, the end 60 'the support 3, but at least the top one to cutting laminate plate 1 applied downward. The opening of the cutting blade 6 is thus not only connected to a pivoting of the cutting blade 6, but also with a relative pivoting movement of the actuating lever 58 relative to the cutting blade 6, wherein the free end 60 'of the low-ter- terarmes 60 from the axis of rotation A of the cutting blade 6 and slides on the top of the cut laminate plate 1 along while exerting a force on the laminate plate 1, which is directed towards the support 3.

There is a locking device 63 is provided, which consists of a threaded pin and a screwed thereon knob 63. The cutting blade 6 has an open-edge slot 64 into which the threaded shaft can enter. If the rotary knob 63 is tightened in this position, the pivotability of the actuating lever 58 is blocked because the cutting blade 6 is clamped between the two steel plates of the actuating lever 58. The operation of the hold-down device is as follows: If a multiple cut is required to cut a wide laminate plate 1, the cutting blade 6 must be swung back upwards after each cut through the kerf in the laminate plate 1. Since the walls of the cutting gap frictionally adhere to the broad side surface of the cutting blade 6, there is a tendency to lift the laminate plate 1 when opening the cutting blade 6. When the lock 63 is released, however, a torque is exerted on the actuation lever 58 when the handle arm 59 is raised, since the latter is easily pivotable about the axis of rotation 61. The hold-down arm 60 tilts down until its end 60 'comes into abutting contact with the top of the laminate plate 1. The end 60 'then rests against the top of the laminate panel 1 and forms a fulcrum about which the operating lever 58 rotates as the handle 62 is pulled further upwards. The cutting blade 6 is then pulled out of the cut slot, with a hold-down force being simultaneously exerted on the laminate plate 1 via the ends 60 '.

For the subsequent cut, either the cutting blade 6 is displaced in the direction of the angle stop 22 or the laminate plate 1 to be cut is displaced in the direction of the cutting blade 6. Will thereafter the

Handle 62 loaded again in the downward direction, so first swiveled the actuating lever 58 in its stop position in which either the stop pin 65 abuts the upper end of the curved slot 66 or the threaded shaft at the bottom of the open-edged slot 64. When this swivel end position is reached, a torque can be applied to the cutting blade 6 via the gripping arm 59 and its then rigid coupling to the cutting blade 6 so that the next cut can be made.

Also in this embodiment, located below the immersion slot 4 is a pull-out plate, which is a Schub- for receiving chips fold 39 forms. In this embodiment, however, the plate is not divided into two parts. It is a single, over the entire length of the frame 2 extending plate provided.

The two respectively the ends of the two mutually parallel hollow sections of the frame 2 closing end face panels 40 form end caps, which form a bottom surface 78 with its underside, with which the laminate cutter can be raised to a substrate. From the end caps 40 project from both sides wings, which are each provided with a Befestigungsboh- tion 67. In this mounting holes 67 mounting screws can be screwed to permanently secure the frame on a countertop.

The embodiment shown in Figures 21 to 29 has only one drawer 39, with the formed below the immersion slot 4 cavity is closed. Also in this embodiment, the drawer 39 consists essentially of a metal strip having an end plate 42 at its end. The end plate 42 forms a handle with which the drawer 39 can be moved back and forth in a guide.

The cutting edge 7 of the cutting blade 6 also forms a fine toothing in this embodiment. These are teeth with a tooth height of about 1.5 mm and a pitch of 3 mm. This gearing forms the chest 6 ^{1 of} the cutting blade. The breast 6 ¹ runs on a contour line, which is designed arcuate. The peripheral edge of the cutting blade opposite the breast 6 ¹ forms its back 6 ", the latter running essentially in a straight line and carrying a plastic handle 21.

Between plastic handle 21 and pivot bearing axis 5 is a cross-sectional reduced area. This cross-section reduced zone is of two Breitseitenausnehmungen 68 formed. These are groove-like depressions 68. The two grooves 68, which are only a few tenths of a millimeter deep, run parallel to one another and are assigned to the wide broad sides of the cutting blade 6 pointing away from one another. The two grooves 68 have a lower step 70 and an upper step 69 which are parallel to each other. In the fully open position of the cutting blade 6 shown in Figures 25 and 26, the steps 69, 70 extend parallel to the support 3. While in this open position, the groove extends in the horizontal direction, the back 6 "of the cutting blade 6 extends in the vertical direction Step 70 of the recess 68 is below the support 3. The upper step 69 of the recess 68 is above the support 3. The distance of the upper step 69 to the support 3 is greater than the material thickness of the plate to be cut.

The function of the bilateral recess 68 or the cross-section reduced area achieved thereby is explained below: If a porous plate, for example laminate plate, to be cut, whose width is greater than the effective length of the cutting edge 7 of the cutting blade 6, the plate must several, consecutive cuts are cut. First, a first cut takes place, which extends over only a part of the width of the laminate plate. This is done by pivoting the cutting blade 6 from an open position to a closed position. Thereafter, the cutting blade must be swung out of the partial section again. This is done with the help of the already described above hold-60 and its hold-down function surface 60 '. The cutting blade 6 is pivoted to the full open position shown in Figures 25 and 26. When the cutting blade 6 is opened, the stopper pin 65 strikes against one end of the arcuate slot 66, as shown in FIG. In the fully open position, in which the back 6 "of the cutting blade 6 extends approximately in the vertical direction, the cross-section reduced zone 68 extends in the horizontal direction immediately above the support 3. The lying on the support 3 workpiece can now be moved further or it can be displaced in the direction of the stop 22, the cutting blade 6. This results in a relative displacement of the cutting blade 6 and laminate plate 1. This shift is therefore smooth, since only the reduced cross-section area 68 is moved through the slot of the laminate plate 1. The bottom of the recesses 68 has a small distance to the walls of the cut gap in the laminate plate 1, so that a Gleitreibungsverminderung takes place.

FIGS. 27 and 28 show a support bracket 71 clipped onto the frame. The latter consists of a U- or V-shaped shaped part whose inner cross-sectional contour corresponds approximately to the outer cross-sectional contour of the frame 2. The support bracket 71 has a head portion 75 which rests on the support 3. In the middle of the head portion 75 has an indentation 76, which projects into the immersion slot 4. On both sides of the head section 75 protrude center sections 74 which follow the outer wall 72 of the two hollow bodies which form the frame 2. Each foot section 73 is adjoined by the two middle sections 74. The foot portions 73 extend substantially in the vertical direction and parallel to each other. They form a lower peripheral edge 73 ', the section from the head 75 is spaced by the height of the support 3. In the transition region between central portion 74 and head portion 75 of the support block 71 has inwardly projecting locking lips 77, which underpin the hollow body forming the frame 2 like a snap. With these locking lips 77, a temporary fixation of the support bracket 71 to the frame 2 is possible.

The laminate cutter can be used with support frame 71 clipped on the frame 2. The supporting block 71 is not located in the cutting area of the cutting blade 6.

The support bracket 71 can be removed from the frame 2 to serve as a support for a laminate plate 1, as shown in FIG. 29. Since the distance between see bottom surface 78 and support 3 and edge 73 'and head section 75 is the same, the laminate plate 1 runs parallel to the Aufständerungsfläche of frame 2 and support bracket 71st
