20220126737 · 2022-04-28 · ·

A foam molded product having a reinforcement layer including a short fiber provided on a surface layer is a cushion member of a seat cushion on which an occupant sits in a vehicle seat. A reinforcement range with the reinforcement layer is set in a predetermined range of an exterior surface along a lower surface of the seat cushion. In the reinforcement range, a plurality of recesses recessed from the exterior surface toward inside of the foam molded product are formed, and the reinforcement layer is formed on the surface layer including an inner surface of each recess. A method of manufacturing the foam molded product includes adhering and depositing the charged short fiber onto a cavity surface of a mold to form a fiber layer, compressing the fiber layer with a silicone rubber sheet, and then molding the foam molded product.

Compression apparatus
11312046 · 2022-04-26 · ·

A compression apparatus (10) for compressing a tubular structure (12) to be formed into a hollow structure (20) such as a pipe comprises contact elements (60) arranged in two sets, (61, 62). The contact elements (60) are adapted to move along a compression section (41) in a coordinated sequence, whereby a portion (12a) of the tubular structure (12) within the compression section (41) is compressed between pairs (63) of opposed contact elements. The apparatus (10) includes registration means (110) for causing respective pairs (63) of opposed contact elements (60) to be maintained in registration with each other while moving along the compression section (41).

Web packaging machines with variable depth forming

A packaging machine is for forming a product cavity in a web including a forming die box defining a recess into which the product cavity is formed. An insert is axially movable in the recess to thereby vary a depth of the recess. A variable depth mechanism selectively moves the insert to vary the depth of the recess. The packaging machine includes a latching mechanism that moves the forming die box into and between a first position in which the forming die box is spaced apart from the die box base and a second position in which the forming die box is supported by the die box base.
