Abstract
From an extruded panel manufactured continuously by means of a twin-belt conveyor, shorter sections may be profitably removed by a cutting device equipped with an adjustable program controller which fixes optimum start-of-cut positions related to a reference point and lying immediately in front of the edges of the extruded panel. The cutting blade is brought into the optimum start-of-cut position in good time before each cut.
Claims10
A method for removing a section of defined length from a continuously manufactured extruded panel comprising a rigid foam core disposed between two outer layers comprising:
- a) bringing a cutting device with its cutting blade into cutting position,
- b) cutting the extruded panel in a manner such that the cutting blade is displaceable with and parallel to the extruded panel at the same rate as the feed rate of the extruded panel to remove a section of the extruded panel,
- c) positioning the cutting blade while moving it back into cutting position, to begin the next cut, if necessary, and
- d) returning the cutting device with its cutting blade to an optimum start of cut position fixed by an adjustable program controller, and
- e) repeating steps b), c) and d).
A device for removing a section of defined length from an extruded panel manufactured continuously on an upstream twin-belt conveyor which panel comprises a rigid foam core disposed between two outer layers comprising
- (1) a cutting device which
- (a) is displaceable with and parallel to the extruded panel at the feed rate of the extruded panel,
- (b) is capable of return travel at increased speed after a section of the extruded panel has been cut,
- (c) has a blade capable of being returned to cutting position after removal of a section of the extruded panel,
- (2) a position sensing element to detect when the blade is in optimum start-of-cut position and
- (3) a program controller to determine the optimum start-of-cut position.
