Title
(EN) Cushioning product and its mfg. method
(ZH) 衬垫产品及其制造方法
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.

一种衬垫转换机器、方法及产品,其特征在于,连接装置可在片状纸料的重叠部分之间提供一种机械互锁,从而可防止衬垫转换机生产的低密度衬垫产品“拉开”。连接装置包括一对可转动的滚压部件,第一个部件(102)绕其周边有多个径向伸出的凸起(120)或齿,凸起具有至少两个轴向间隔部分,其间形成一个凹槽。第二滚压部件(100)包括至少一个轴向冲压部分(132),它包括一个周边部分,在滚压部件的旋转过程中,该周边部分可以装入第一滚压部件的凹槽中。周边部分与第一滚压部件的凸起相配合,从而通过每个角边在片状纸料的重叠部分制成一行狭缝,这样就产生至少一行可以互锁纸料重叠部分的接头。第二滚压部件可包括靠近冲压部分的另一个轴向部分,这个轴向部分有多个与第一滚压部件其中一个轴向部分的凸起相啮合的径向伸出的凸起(120)。滚压部件可由多个平圆盘部件并排叠在一起构成,其中一些轴向部分由一个或多个平圆盘部件构成。
