Abstract: A sliding makeup implement includes a pair of case members that are obtained by dividing a case into two in a protruding direction of a rod-shaped core, one divided case member being slidably combined with the other divided case member. Sliding grooves are respectively formed in inner surfaces of the divided case members for arranging the rod-shaped core so that the core can be advanced and retracted in an axial direction. A core holder is movable along the sliding grooves and holds the core at a base end thereof. Coupling means for pushing out the core by means of one case member and for bringing the one case member and the core into a coupled state when the pushed-out core is returned to its original position, and for bringing the one case member and the core into an uncoupled state when the core is left at the pushed-out position.

Abstract: There is provided an apparatus for producing a paving block comprising a block substrate and a solid top layer selected from a tile-like layer and a cured cement mortar layer firmly bonded onto the upper surface of the block substrate. The apparatus comprises a mortar applicator (21) consisting essentially of a mortar container and a masking bottom board (23) having an opening (24) to be located on the back of a top layer (1-2) or the upper surface of a block substrate (1-1) during application of cement mortar thereon, a clamping plate (25) to be located on the top layer (1-2) placed on the block substrate (1-1) during bonding them, and a scraping frame (26) for scraping excess mortar remaining on the side surfaces of the bonded block. When the apparatus is used to produce a novel paving block comprising a block substrate and a solid top layer having a plane dimension smaller than the substrate, squeeze-out deposits (6) of the cement mortar (7) are further formed around the bonded top layer (1-2).

Abstract: A system for making a composite block, including a block body formed of mortar or concrete and a covering material such as a tile, natural stone or mortar sheet applied to the upper surface of the block body, includes an applicator for applying an adhesive material to the block body or covering material. The system also includes a press for loading vibration and/or pressure on a composite block assembly including the block body, the covering material placed thereon and an adhesive material disposed therebetween. Additionally, this system includes a finishing mechanism for finishing the pressed composite block assembly into the composite block by passing it through a hole of a size substantially corresponding to the contour of the composite block. The hole is formed through a scraper constructed from a flexible material.

Abstract: The fracture-free paving block comprises a cement block substrate and a top solid layer, and is characterized in that the top layer is selected from a cured cement mortar layer and tile-like layer firmly bonded to the substrate with cement mortar; the top layer is bonded to the block substrate with lateral margins of 1 to 8 mm wide in horizontal distance from the peripheral edges of the substrate; and the vertical distance from the surface of the top layer to the peripheral edge of the substrate is 5 to 50 mm.

Abstract: The fracture-free paving block (1) comprises a cement block substrate (1-1) and a top solid layer (1-2), and is characterized in that the top layer is selected from a cured cement mortar layer and a tile-like layer firmly bonded to the substrate with cement mortar; the top layer is bonded to the block substrate with lateral margins (2) of 1 to 8 mm wide in horizontal distance (1.sub.5) from the peripheral edges of the substrate: and the vertical distance (1.sub.6) from the surface of the top layer to the peripheral edge of the substrate is 5 to 50 mm. The method for producing the paving block (1) having a tile-like top layer comprises applying adhesive cement mortar between the back of the top layer (1-2) and the upper surface of the substrate (1-1); placing the top layer on the substrate with the above-mentioned margins (2) of the substrate surface: and applying vibration and/or pressurization between the top layer and the substrate.
