Title
(EN) CUSHIONING CONVERSION MACHINE AND METHOD WITH STITCHING ASSEMBLIES
(FR) MACHINE DE TRANSFORMATION DU PAPIER EN PRODUIT DE CALAGE ET PROCEDE METTANT EN ×UVRE DES ENSEMBLES DE PIQUAGE
Abstract
(EN)
A cushioning conversion machine, method and product characterized by a connecting assembly that provides a mechanical interlock between overlapped portions of sheet-like stock material to prevent 'unzippering' of a low density cushioning product produced by the cushioning conversion machine. The connecting assembly comprises a pair of rotatable stitching members, a first one (102) having a plurality of radially outwardly extending projections (120), or teeth, around the circumference thereof, with the projections having at least two axially spaced apart segments defining a recess therebetween. The second stitching member (100) includes at least one axial punch segment (132) which includes a peripheral edge portion dimensioned to be received in the recess in the first stitching member during rotation of the stitching members. The peripheral edge portion is cooperative with the projections of the first stitching member to produce at each corner edge thereof a row of slits in the overlapped portions of the sheet-like stock material, thereby forming at least one row of tabs for interlocking the overlapped portions of the stock material. The second stitching member may include another axial segment relatively adjacent the punch segment, such other axial segment having a plurality of radially outwardly extending projections (120) meshing with the projections of one of the axial segments of the first stitching member. The stitching members may be formed by a plurality of flat disc members stacked side-by-side with the several axial segments being formed by one or more of the flat disc members.

L'invention concerne une machine de transformation du papier en produit de calage, un procédé et un produit caractérisés par un système d'assemblage assurant une solidarisation mécanique des parties à recouvrement du papier stratiforme pour empêcher le 'déroulage' d'un produit de calage à faible densité fabriqué par la machine de transformation du papier. Ce système d'assemblage comporte une paire d'éléments de piquage rotatifs, un premier élément (102) présentant une pluralité de saillants (120) s'étendant radialement vers l'extérieur, ou des dents, autour de sa circonférence, ces saillants possédant au moins deux segments espacés axialement et définissant un évidement entre eux. Le deuxième élément de piquage (100) comprend au moins un segment axial de perforation (132) pourvu d'une partie marginale périphérique dimensionnée pour se loger dans l'évidement du premier élément de piquage lors de la rotation des éléments de piquage. Cette partie marginale périphérique coopère avec les saillants du premier élément de piquage pour pratiquer à chaque bord cornier une rangée de fentes dans les parties à recouvrement du papier stratiforme, formant ainsi au moins une rangée de pattes pour solidariser ces parties à recouvrement. Le deuxième élément de piquage peut comporter un autre segment axial relativement adjacent au segment de perforation, cet autre segment axial présentant une pluralité de saillants s'étendant radialement vers l'extérieur (120) et engrenant avec les saillants de l'un des segments axiaux du premier élément de piquage. Les éléments de piquage peuvent être constitués d'une pluralité de disques plats empilés côte à côte, plusieurs segments axiaux étant constitués d'un ou de plusieurs disques plats.
