In rolls of winding equipment in a hot-rolling factory, each roll includes a lower cladding layer formed on the surface of the roll barrel and a self-fluxing alloy layer formed on the lower cladding layer by thermal spraying and containing carbide particles dispersed therein. The lower cladding layer includes an Fe-based cladding layer which has a Shore hardness of 60 or greater and which contains, in terms of mass %, 0.1-0.4 C, up to 2.0 Si, up to 3.0 Mn, 1.0-15.0 Cr, and 2.5-5.0 Ni. The lower cladding layer further contains one or more of Mo, V, and Co, the contents of Mo, V, and Co being 0.1-5.0 mass %, 0.1-3.0 mass %, and 0.5-5.0 mass %, respectively.

A roll for winding equipment in a hot rolling factory is obtained by forming a base build-up layer on the surface of the body of the roll and forming on the base build-up layer a self-fluxing alloy thermal spraying layer, in which carbide particles are dispersed. The base build-up layer has a Shore hardness of 60 or higher and includes an iron-based build-up layer that contains, in terms of mass %, 0.4-1.0% of C, 2.0% or less of Si, 3.0% or less of Mn, 1.0-15.0% of Cr and 0.5-5.0% of Nb.

The invention relates to a method for winding a metal strip (1) into a reel with a winding mandrel (2), to which the metal strip (1) is routed through a pair consisting of a first and a second driver roller (5, 6), at least one of which is driven. The method is characterized in that a difference between the strip speed (V.sub.B) of the metal strip (1) and the speed) (v5, v6) of the driver rollers is adjusted on the basis of measuring, from measurable process variables, the strip speed and the speed (v5, v6) of at least one of the driver rollers (5, 6).

A method is provided for the handling of coreless auger produced by an auger production machine from which the coreless auger emerges with a linear motion component and a rotational motion component. The method includes guiding the rotating auger for linear movement away from the production machine toward a temporary storage facility that has a cylindrical receptacle rotatable about its own axis and a coaxial rotatable feed guide having an axial inlet for formed auger and an outwardly directed outlet for directing formed auger toward an inner periphery of the cylindrical receptacle; rotating the cylindrical receptacle and allowing the feed guide to rotate about the axis of its inlet that is roughly coincident with the axis of auger entering the axial inlet of the feed guide such that the outwardly directed outlet may move around the interior of the receptacle in a circular path to direct auger toward the inner periphery of the cylindrical receptacle and form a coil thereof. The cylindrical receptacle is rotated at a speed selected to counteract the rotation of the auger about its own axis.

An absorption apparatus 1 that is an example of a loop amount absorption apparatus of a slitter line to which the present invention is applied is disposed in a region of a loop pit 3 provided in the slitter line 2. The absorption apparatus 1 includes a negative pressure roll 9 that grips and conveys strips and an up-down moving device 10 that enables the negative pressure roll 9 to move up and down. By gripping and conveying the strips 14 by the negative pressure roll 9, two loops 15 of the strips are formed. The negative pressure roll 9 includes a rotating shaft 16, an inner cylinder 17, an intermediate cylinder 18, and a non-woven fabric laminated outer layer 19.
