(FR) MACHINE DE TRANSFORMATION DU PAPIER EN PRODUIT DE CALAGE ET PROCEDE METTANT EN OEUVRE DES ENSEMBLES DE PIQUAGE
Abstract
(EN)





A cushion 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.
