摘要:
A resilient material shaped into a bent strand with a preferred length from 1.5 to 7 inches forms a filling element for cushions, pillows and upholstered articles. The strand may be bent so as to have a Z-shape or an S-shape or a V-shape or a C-shape along a portion of its length. The length of the strand is greater than its nominal cross-sectional thickness. A quantity of filling elements (e.g., the filling material), preferably formed from flexible, open cell polyurethane foam, is inserted or blown into a casing for a cushion, pillow or upholstered article. Following compression, the filling elements rebound substantially to their uncompressed state without clumping together or leaving pockets within the casing.

An apparatus for continuously shaping a compressible or cellular polymer material, such as polyurethane foam, by cutting portions of the material from a surface of a slab of the material includes a compression roller, a support surface, a blade and a moving patterned platform interposed between the compression roller and the support surface. The moving patterned platform, preferably an endless belt or a series of interconnected panels, defines at least one recess, and may define a pattern of recesses of complex or simple shapes and at various depths. When the slab of cellular polymer material is compressed between the compression roller and the support surface, a portion of the material fills the recess or recesses in the moving patterned belt. The blade then transversely cuts from the surface of the slab a portion of the material within the recesses in the platform just as the slab emerges from between the compression roller and the support surface. After the cut portions are removed, the resulting product has a profile-cut surface with cut-out portions corresponding in mirror image to the pattern and shape of the recesses. Depending upon the compression factor of the material, the cut-out portions will substantially correspond in depth to the recesses provided on the moving patterned platform.

A method for shaping a slab of compressible or cellular polymer material, such as polyurethane foam, by cutting portions of the material from one surface uses a compression roller, a support surface, a blade and a moving patterned platform interposed between the compression roller and the support surface.

When the slab of cellular polymer material is compressed between the compression roller and the support surface, a portion of the material fills the recess or recesses in the moving patterned belt. At least a portion of the compressed material within the recesses is then cut from the surface of the slab by the blade just as the slab emerges from between the compression roller and the support surface.

摘要:
A gutter insert formed of a flexible open cell porous foam has five or more sides and forms an inverted “V” or check-mark shape. Four gutter inserts may be cut from one column of foam material, thereby reducing foam waste. The four gutter inserts may be shipped nested together in columnar form, and separated at the jobsite just before installation.
