Description

Known machines for puttying plywood sheets using a hopper for putty and drive rollers for agitating plywood sheets under the bunker do not provide the required quality of putty while simultaneously processing the entire width of the sheet.

In the described machine, this disadvantage is eliminated. For this, the bunker is equipped with a drive putty roller located inside the bunker with a gap above the passage w; there is a plywood sheet under it and a plate spring putty spatula whose length is equal to the length of the putty roller. For the final removal of excess layer of putty from plywood, a second sprue trowel is used, located at the end of the machine.

The drawing shows schematically a machine for puttying plywood sheets, a general view.

The machine consists of a bunker / for putty, inside which the drive putty roller 2 is fixed, and a spring plate spatula 3 attached to the bunker over the entire width of the machine, and the length of this putty is equal to the length of putty 2 2. The second spring putty knife 4 is located at the end of the machine and serves for the final removal of excess from the plywood - a layer of putty. Under the spatula 3 there is an idle shaft 5, and under the spatula there is a 4-idle shaft 6. These shafts are designed to level the plywood at the points of pressure of the spatulas and reduce its weight on the machine bed. For the supply of sheet 7 of plywood under the bunker, the drive shafts of 8 p .9 are used.

The process of applying putty on plywood is as follows.

Depending on the width of the plywood sheet, two movable partitions are placed in the bunker, resting on the putty roller, and putty is laid between the installed partitions. At its turn, the roller 2 is covered with a layer of putty and across the entire width of the sheet the putty is applied with a roller to the moving under the bin 127149 2 -

Rum plywood sheet, while the plate spatula 3 removes all excess LAYER putty and leaves it only in the recesses. In those cases where the spatula 3 for any reason does not remove excess, the institute layer putty, this role will be performed by another spatula 4, it is ush, according to the cyntecTEty stripping spatula.
