A floor tile for a raised floor. The floor tile is defined by a shallow upwardly-opening metal pan defining a shallow compartment in which a main preformed one-piece concrete block is secured. The main concrete block is preferably formed from a plurality of one-piece preformed concrete sub-blocks which are adhesively adhered in sideward abutting relationship to define a plan profile corresponding to the main concrete block. The main concrete block is then adhesively secured within the compartment of the metal pan.

Synthetic shingles are made and treated, such that upper surfaces thereof that are to be weather-exposed in the installed condition, are scuffed, abraded, or scraped in such a manner that different visual appearances occur between abraded zones and unabraded (or lesser abraded) depressions, to enhance the natural-appearing materials that the synthetic shingles are designed to resemble. The shingles and the abrading medium have motion relative to each other. The abrading medium may take on various forms, such as a roller, a brush, a pad, etc. Some portions of the upper surface of the shingle remain unabraded, preferably being those portions that are depressed relative to higher portions of the shingle. The shingle may be of a single layer construction, or a multi-layer laminate.

An adjusting device for the conveying belt of a planer includes a fundamental plate assembled on the base of a planer. The fundamental plate has its rear end disposed with a rear roller unit connected with the base of the planer and composed of two adjusting plates and a rear roller. The two adjusting plates are respectively bored with longitudinal insert slots preset in number to enable the adjusting plates to be slidably assembled on the fundamental plate. Each adjusting plate has its front end extending outward vertically and forming a positioning wall pivotally fixed thereon with a positioning member and movably fastened on the base of the planer. The adjusting device for the conveying belt of this invention is simple in structure and easy to be assembled, lowering processing and assembling cost.

A linear sander has a base, at least one rough abrasive assembly, at least one fine abrasive assembly and a reciprocating device. The base has two sides and a belt. Each rough abrasive assembly is mounted on the base above the belt and has a rotating axle and an abrasive brush mounted around the rotating axle. Each fine abrasive assembly is rotatable mounted on the base is aligned obliquely to the mounting shafts and has two mounting brackets, two mounting shafts and multiple abrasive rollers. The reciprocating device is connected to the abrasive assembly and has a pivot bracket mounted securely on one of the mounting brackets, two drive bars mounted on move the abrasive rollers linearly along the mounting shafts and a linear driver connected to the drive bar.
摘要:
A machine for finishing an object comprising feed members to feed the object along a reference plane (P1), and at least a work station provided with a tool which contacts the object in a work zone (Z) near the reference plane (P1). The machine comprises two lateral supporting walls arranged substantially orthogonal both to the reference plane (P1) and also to the median plane (P2), which support the work station laterally, in order to define with the work station a modular structure able to be selectively associated with other modular structures along the direction of feed of the object.
摘要:
An abrading group comprises a plurality of abrading units rotationally mounted on a crossbar extending along a transverse direction that is transverse with respect to an intended advance direction of pieces to be abraded, a driving arrangement for rotating each abrading unit around a longitudinal axis thereof, a further driving arrangement for oscillating said crossbar along said transverse direction, said further driving arrangement is such as to oscillate said crossbar also along said advance direction.

A sanding machine includes a conveyer and a sanding assembly for sanding a workpiece by moving the sanding assembly in multiple linear and/or nonlinear motions relative to the conveyed workpiece.
摘要:
A rotary grinding machine includes a rotary grinding member for grinding a workpiece on a workpiece feeding member. The grinding member is coupled with an output shaft of a motor through a drive transmission mechanism. The feeding member is coupled with the output shaft of the motor through a reduction gear mechanism, a transmission shaft and an endless tensible transmission member. To maintain an operating tension of the tensible transmission member when the feeding member is moved relative to the grinding member, a tensioning mechanism is disposed to enable effective transmission of a drive force from the reduction gear mechanism to the feeding member.
摘要:
The facing machine for hard-fired ceramic tiles comprises: a structure for supporting, and setting the cutting depth of, at least one pair or rotary rollers at a grooving station, the axis of said rollers lying transverse to the infeed path of said tiles as carried on a belt transport; said rollers comprising a plurality of disks formed with diamond-tipped cutting teeth and a facing station comprising a plurality of vertical-axis grinding wheels with abrasive diamond-tipped tooling; said rollers are carried on a common supporting structure, being adjustable in height to set the tool cutting depth in the tile; said structure being pivotable about a parallel shaft to the work surface in a transverse direction to the feed direction of the surface, and being associated with a device for adjusting and inhibiting the pivotal movement of the structure in order to accommodate varying cutting diameters of the rollers at said station.
