The invention relates to the woodworking industry, in particular to the production of lengthy blanks.

The purpose of the invention is to increase productivity by combining operations.

Fig. 1 is a diagram of the lines of the splice of workpieces along the length; figure 2 - scheme of cutting defects and f | ermirovanny spike.

 The length of the blanks along the length of the HJe includes the supplied blanks 1 to the milling and milling machine 2, the device ™ for applying glue 3 to the billets 1, the press 4 and the longitudinal milling machine with | ganok 5 from the miter Saw 6 and pa-K |

Implement as follows.

: The workpiece 1 is fed to the trimmer-milling machine 2, where they cut out the ef | ekty and form a toothed spike. Next, the workpiece 1 goes to the device 3 for applying glue to the end face of the G (ethos 1. The ends of two workpieces 1 with the applied binder are joined and pressed. The workpieces 1 are machined on a longitudinally-milling machine 5 and stored in a foot bagger 7.: Example 1. Used blanks 1 80 mm wide and 16 mm thick, with defective areas of 50 mm. Distance between defective areas 300 to 500 mm. First, the defective ones were removed by cutting them with a miter machine. defective segment 70 mm. Further defect-free from cutting lengths of 300-500 mm were applied to the splice line along the length, where a single end of the segment (10 mm skip size) was sawn off at the tenoning machine of the sleep | 1a and the spikes were milled on it, and then the second end of the segment was subjected to the same treatment. machining of both ends was applied to the spikes glue and spliced from

cutting lengthwise. :

Example 2. They took workpieces 1 with a width of 80 mm and a thickness of 16 mm with dimensions of defective areas of 50 mm. The distance between the defective zones is 400 mm. Defective areas were removed by milling using a milling cutter with a diameter of 70 mm. At the same time, the same milling cutter formed toothed spikes with a turn about the longitudinal axis of the workpiece 1 on the polo; guilt step. The length of the removed defective segment is 70 mm. Next, glue was applied to one of the adjacent ends and spliced lengthwise.

Example 3, Took the workpiece 1 with a width of 80 mm and a thickness of 16 mm with dimensions of defective areas of 65 mm. The distance is irae between the defective zones 400 mm. The defective zones were installed on the miter machine. The size of the cut off defective cut is 85 mm. Next, the defect-free sections 400 mm long were fed to the splice line along the length, where one end of the segment (allowance size 10 mm) was first sawed off with a pinching machine and the spikes were milled on it, and then the second end was machined. After processing both ends, glue was applied to the spikes and spliced into lengths.

The total length of the removed segment is 85 + 10x2 105 mm.

Formula of the invention

The method of splicing the workpieces along the length, including the removal of defects, the formation of jagged spikes using a milling cutter, applying glue, pressing and cutting, which, in order to increase productivity by combining 5 operations, remove defects and form jagged spikes jointly with a turn of the cutter in imocosity, perpendicular to the plane of the workpiece and passing through its longitudinal axis by half the spike pitch.

After processing both ends, glue was applied to the spikes and spliced lengths along the length.

The total length of the removed segment is 85 + 10x2 105 mm.

Formula of the invention

A method of splicing workpieces along the length, including removing defects, shaping jagged spikes using a milling cutter, applying glue, pressing and cutting, which, in order to increase productivity by combining operations, removing defects and shaping jagged spikes, is carried out together with a turn milling cutters in imocosity, perpendicular to the plane of the workpiece and passing through its longitudinal axis by half of the spike pitch.
