In this molded surface fastener, plural engaging elements having a stem portion and an engaging head portion formed integrally on the stem portion are standing on the base portion, at least one pawl portion having a pawl width dimension narrower than a width dimension at a boundary between the stem portion and the engaging head portion is protruded on an outer peripheral edge part of the engaging head portion, and a back surface of pawl of the pawl portion is formed at different angles with respect to a back surface of head portion of the engaging head portion. Such a molded surface fastener of the present invention has a substantial engaging force with respect to a female surface fastener and can make a texture of its surface comfortable.

The present invention relates to a stable mat (10) based on thermoplastic materials, comprising a core of compacted plastics (14), the cohesion of which is provided by spot thermal fusion (18) in the core of the mass, and a skin obtained by surface thermal fusion and/or a thermoplastic shell (12) firmly attached to the core by localized thermal fusion. Such a mat may serve as bases for civil engineering constructions, for the distribution of loads in the case of loose, unstable, or marshy soils, the stabilization of embankments or of unstable soils, earthquake-resistant protection of foundations of structures and composition of absorbent ballasts of railroads. They may also be used for the manufacture of prefabricated road elements.

A method is provided for manufacturing recyclable inorganic paper, which has a composition comprising 60-85 wt % mixture of natural inorganic mineral powders, inorganic glass powders, and sand powders, 5-40 wt % bonding agent of polypropylene (PP), and 1-5 wt % assisting agents, through the following steps: feeding and mixing of the constituents of the composition; stirring and mixing the composition; pressing to cause bi-directional extension of the composition so as to form a sheet; subjecting the sheet to operation of a high density squeezing machine for further mixing and pressing the sheet; reversely turning and shaping the sheet for further extension of the sheet; and continuous compression and extension of the sheet to induce further bi-directional extension of the sheet in both lateral and longitudinal direction and to control thickness of the sheet.

An insulating sheet is pushed into a first mold portion, and formed in a first shape along a shape of the first mold portion. The insulating sheet of the first shape inside the first mold portion is pushed into the second mold, and is deformed by a front mold portion, a front guide portion, and a bent convex portion of the front mold, and a rear mold portion and a rear guide portion of the rear mold, and is formed in a second shape. The insulating sheet of the second shape is inclined such that the front end portion overlaps the rear end portion in a first direction, and the width in a front-rear direction becomes narrower toward the front and the rear end portions. The insulating sheet inserted in the second mold and formed in the second shape is inserted into a slot of a stator core.
