The invention relates to an assembly for producing an endless corrugated cardboard web laminated on at least one side, the assembly comprising a first corrugating roller and a second corrugating roller for producing a corrugated web provided with a corrugation as well as a glue application assembly. The glue application assembly comprises a glue container for receiving glue, a glue application roller for applying the glue disposed in the glue container to tips of the corrugation of the corrugated web, and at least one glue wave inhibiting assembly arranged in the glue container for inhibiting the formation of glue waves of the glue disposed in the glue container. The assembly for producing an endless corrugated cardboard web laminated on at least one side further has a pressure assembly for pressing a cover layer against the tips, provided with glue, of the corrugated web.

The present invention relates to a flexible laminate of films of thermoplastic polymer material mainly for applications in which relatively high yield strength and ultimate tensile strength is required, and a method and apparatus for its manufacture. The laminate comprises a monofilm formed or multifilm-formed ply (A) and another monofilm-formed or multifilm formed ply (B) both mainly consisting of orientable thermoplastic polymer material, in which A has a fluted configuration and B on a first side is adhesively bonded in bonding zones to the crests on a first side of A, in which B also has a fluted configuration, the flute direction of B forming an angle from generally about 30° up to and including 90° to the flute direction of A and the said bonding zones being on the crests of the first side of B to produce spot bonding with the crests on the first side of A, the wavelengths of the flutes in A and/or B are no longer than 5 mm, and the wavelengths of the flutes in both A and B are less than 10 mm.

The present invention relates to absorbent articles for retaining body fluids such as urine, menses, or fecal material. In particular, the absorbent article of the present invention comprises a liquid handling member that collapses at a pressure between 2756 Pascal (0.4 psi) and 3447 (0.5 psi) in order to reduce the likelihood of causing skin marking.
摘要:
A buffer material of the present disclosure is a buffer material including a buffer sheet that contains cellulose fibers and a binding material binding the cellulose fibers and has a sheet shape, in which the buffer sheet has a plurality of first projections that protrude toward at least one surface side and are provided in a lattice shape. Further, it is preferable that the buffer sheet further have a plurality of second projections having a projection amount that is greater than a projection amount of the first projections.

摘要:
A sheet of coated abrasive material including a backing having abrasive on one surface and loops projecting from its other surface by which the sheet of coated abrasive material can be held by hooks on the support surface of a pad. The backing comprises a polymeric bonding layer defining its rear surface. The sheet of coated abrasive material comprises a nonwoven sheet of longitudinally oriented fibers having anchor portions bonded in the polymeric bonding layer at spaced bonding locations, and arcuate portions projecting from the rear surface of the backing between the bonding locations to provide the loops.
摘要:
A sheet of loop material adapted to be cut into pieces to form loop portions for fasteners of the type comprising releasably engageable hook and loop portions, or to be incorporated into items such as disposable garments or diapers or into sheets of abrasives. The sheet of loop material includes a sheet of longitudinally oriented fibers having anchor portions and arcuate portions projecting in one direction away from the anchor portions, and a layer of thermoplastic backing material extruded onto the anchor portions to bond to the anchor portions and form at least a portion of a backing for the loop material. The thermoplastic backing material can also bond the sheet of fibers to a sheet of backing material.
