A splicing and truss assembly apparatus for securing connector plates (63, 64, 65; 106) to sides of wood members (20, 21; 103a, 103b) includes a pair of entrance pinch rollers (A), a track system (B), two pairs of assembly rollers (C) and a roller drive (D). The assembly rollers (C) continuously drive the wood members (20, 21; 103a, 103b) and compress the toothed connector plates (63, 64, 65; 106) into embedded engagement with the wood members as they pass through the rollers (C). Adjustability of both entry pinch rollers (A) and assembly rollers (C) is provided for on-edge or flat orientation of the wood members. To provide camber for the finished truss joint, the truss is assembled upside down with entry and departure tracks (23a) on either side of the assembly rollers (C) oriented in slightly sloping relation. In order to splice wood members (106), the assembly rollers (C) are semi-cylindrical of which two pairs of different size are used to assure positive drive abutment. The pairs of rollers (C,A) are provided with synchronized drive. |
