Abstract

Provided are: a strip end detection device that is capable of accurately detecting a strip end and reducing maintenance work burden; and a brushing device comprising the strip end detection device. This end detection device 7 moves back and forth in the width direction of a strip 2 together with a brush roll 3 and detects the width-direction ends of the strip 2. The end detection device 7 comprises: a light projection unit 8 for emitting light from the front or back surface side of the strip 2 toward the other side, a reception unit 9 that is disposed on the opposite side of the strip 2 from the light projection unit 8 and receives the light projected from the light projection unit 8, a plurality of covers 100 for individually covering the projection unit 8 and reception unit 9, air jetting means 11 that are provided in each of the covers 100 and are for continuously jetting air toward the light projection unit 8 and light reception unit 9, and water jetting means 12 that are provided in each of the covers 100 and are for jetting water toward the light projection unit 8 and light reception unit 9 at a prescribed timing.

Abstract

The present invention provides a roll shaft having high corrosion resistance and rigidity against bending, and a brush roll comprising the roll shaft. The roll shaft 2 is for use in a brush roll 1 for brushing a strip of metal sheet. The roll shaft includes: a shaft body 7 to which multiple annular discs 4 having multiple brush bristles 5 implanted around the outer peripheral edge of the discs 4 are attached; key bases 8 attached to recessed grooves 72 provided on the outer peripheral edge of the shaft body 7, the key bases comprising keyways 80 into which insertion members 6 projecting from the inner peripheral edge of the annular discs 4 are fitted, and the key bases 8 comprising a corrosion-resistant metallic material, a corrosion-resistant alloy, or a corrosion-resistant resin material.

Abstract

Provided are: a bristle material for brushes, which has adequate polishing power and is capable of suppressing abrasion of a rolling mill roll as much as possible; and a brush roll. A bristle material (1) for brushes, which is used for a brush roll (B) for polishing a rolling mill roll that rolls a metal plate (S), and which comprises one or more monofilaments (2) formed from a thermoplastic resin and containing polishing material particles. The polishing material particles have a hardness that is lower than the hardness of the rolling mill roll but higher than the hardness of the metal plate (S).

Abstract

Provided is a bristle element for a brush and a method of manufacturing the bristle element for the brush such that productivity can be improved. The bristle element for the brush is provided with a core thread (2) containing first monofilaments (21); and a covering thread (3) containing second monofilaments (31) which are bonded to the core thread (2) in a state where the second monofilaments (31) are wound around the outer periphery of the core thread (2). The second monofilaments (31) each comprise at least two layers consisting of a central section (311), and an outer peripheral section (312) having a melting point higher than that of the central section (311). The outer peripheral section (312) is bonded to the core thread (2) by being heat-fused to the core thread (2).
