A method and apparatuses are disclosed for making shingles. The method consists of clampingly holding a block of material to be cut and conveying such block while it is clamped along a selected path through the clamping mechanism and causing relative movement between two cutting means which are inclined relative to one another to firstly cut a shingle from the block tapering in one direction and followed by a second shingle tapering in the opposite direction. The apparatus includes means for receiving and clampingly holding blocks as they are fed in sequence thereto and means to feed the block while it is clamped. The block is fed into the path of two cutting mechanisms and upon relative movement of the clamped block and the cutting mechanisms, the first cutting mechanism cuts first one shingle tapering in one direction and the second mechanism thence cuts a second shingle from the block tapering in an opposite direction, the cutting mechanisms being inclined relative to one another providing the appropriate taper for the shingles cut thereby from the block. The cut shingles are conveyed to an edge trimming apparatus and are moved by conveying means through at least one trimming station having cutting means for trimming the edges of the shingle. Upstream of the cutting means there is located a scanner that provides information to a computer that processes the information and actuates movement of the trimming saws to trim the edges of the shingle minimizing the amount of waste for each shingle. Defect cutting devices are also provided for removing defects in shingles and they too are controlled by information provided by the computer.
A method of making tapered shingles comprising:
Apparatus for cutting tapered blocks in sequence one after the other from blocks of material, comprising:
Apparatus for cutting blocks of wood of selected length into shingles and which shingles taper in thickness from one end to the other, comprising:
Apparatus for cutting tapered shingles from blocks of wood comprising means to clampingly hold a block and feed the clamped block incrementally into a path traversed by cutting devices, first and second cutting means movable alternately along predetermined paths across the direction of feed of the block for cutting shingles from the leading face of the block when it is fed in increments into the path of the cutting means, said first and second cutting means being inclined in opposite directions relative to one another for alternately cutting firstly a shingle tapering in thickness from one end to the other, followed secondly, by a shingle tapering in thickness from one end to the other in the opposite direction and means inter-relating the incremental feed and movement of the respective first and second cutting means along their respective paths.
Apparatus for conveying shingles flatwise and means associated therewith to align the shingles being conveyed to ensure edge trimming of the shingle is squared with the butt end of the shingle, said apparatus comprising a conveyor having bars each with a shingle engaging edge disposed perpendicular to the path of travel and movable along said path of travel over a shingle supporting flat surface and means on said shingle supporting flat surface, over which the shingles pass, impeding sliding movement of the shingle thereby causing the butt end of the shingle to come into alignment with said shingle engaging edge of the bar as it is pushed thereby over the movement impeding means.
