Headstock for a panel cutting machine

A headstock of a panel cutting machine for cutting panels having a laminate, said headstock comprising:

• conveyor means for feeding a laminated panel in a feed direction on a feed path;
• panel cutting means comprising a disc blade rotatably mounted on a first shaft and disposed in said feed path for cutting the panel;
• panel cutting drive means comprising a motor connected to said panel cutting means for rotating said panel cutting means and cutting the panel;
• laminate cutting means comprising a rotary milling blade mounted on a second shaft spaced from said first shaft and disposed in the feed path in front of said panel cutting means in said feed direction and in alignment with said panel cutting means for cutting the laminate of the panel;
• a plate rotatably mounted on said first shaft of said disc blade, said second shaft with said milling blade being rotatably mounted on said plate;
• laminate cutting drive means connected to said laminate cutting means for rotating said laminate cutting means;
• and laminate cutting pressure means comprising a spring loaded member engaged with said plate for biasing said plate and said milling blade thereon downwardly at a selected pressure onto the panel.

A headstock of a laminated panel cutting machine comprising, a conveyor table for advancing a panel in a feed direction on a feed path, a circular saw having a disc blade rotatably mounted and disposed in the feed path for cutting the panel, said disc blade being mounted on a shaft, a motor for driving said disc blade shaft, a plate pivotally mounted on said disc blade shaft, a laminate cutting tool rotatably mounted on said plate and disposed in the feed path in advance of said disc blade in the feed direction and in alignment therewith for cutting the laminate of the panel, a cross belt connected between said disc saw shaft and said laminate cutting tool for rotating said laminate cutting tool in a direction opposite from the rotation of said disc saw and in a direction adjacent a panel tangentially the same as the feed direction of the panel, a spring loaded member engaged with said plate for biasing said plate with said laminate cutting tool toward the panel to be cut at a selected pressure, a housing disposed around said plate and said laminate cutting tool having a slot adjacent a panel to be cut for exposing a portion of said laminate cutting tool to the panel, an adjustment means engaged with said casing for adjusting the depth of the cut of said laminate cutting tool in a panel to be cut to a depth equal to at least the thickness of the laminate, wherein a pre-incision is made in the laminate of the panel after which the panel is cut by said disc blade.
