FOLDING DEVICE FOR MAKING TWO PARALLEL FOLDS ON A SHEET OF PAPER OR THE LIKE Russian patent published in 2022 - IPC B42C5/00 B31F1/00 

FIELD: bending devices.

SUBSTANCE: bending device for making two parallel folds on a sheet, while the device (1) contains two clamps (5) with a bending edge (9), each formed by two clamping strips (6) with clamps (7) that can move relative to each other between open position and closed position, and at the same time the clamps (5) that feed the sheet (4) are placed opposite each other with their bending edges (9), parallel and opposite at a distance (B) equal to the required distance between the folds to be made, and the folding device (1) also contains means (10) for moving the clamps (5) to their closed position relative to each other in such a way that one of the clamps (5) with its bending edge (9) makes a circular motion around the bending edge (9) of the other clamp (5) to form both parallel folds at the bending edges (9) of both clamps (5).

EFFECT: bending device improvement.
