METHOD AND MACHINE FOR PRODUCING CROSS-BRACING INSERTS DESIGNED FOR DIVIDING BOXES INTO SECTIONS AND CROSS-BRACING INSERTS OBTAINED BY SAID METHOD

摘要

The invention concerns a method and a machine for automatic production of inserts made of undulated board sheet, for dividing boxes into sections. The method consists in: forming two opposite stacks of blanks, namely one first stack consisting of first blanks (1) designed to form by folding a first part of cross-bracing insert or a first cross-bracing insert, and a second stack of blanks (2) designed to form a second part of cross-bracing insert or a second cross-bracing insert; gripping on one side the first blank (1), and on the other side the second blank (2); simultaneously moving by a pivoting motion the first blank (1) and the second blank (2) so as to bring them in contact with each other by the edge in a common horizontal plane, then in simultaneously folding down on either side of the central panel, the two sets of flaps to form two half-cross-bracing inserts or two cross-bracing inserts
