Embodiments of a paint roller support (10) for rotatably supporting a conventional paint roller cover (8) are disclosed. In one embodiment, a paint roller support comprises a frame (12) having an elongated shaft (18) and at least one hub (24, 26) rotatably coupled to the shaft for supporting a conventional roller cover. A locking spring (16) exerts a retaining force against an inner surface (12) of the roller cover for frictionally retaining the roller cover on the hub while the paint roller support is used to deliver paint to a surface. Embodiments of a method for manufacturing a paint roller support also are disclosed.

The invention relates to a segmented roll comprised of a plurality of end-to-end mounted roll segments (10, 10'), each adapted to rotate on bearings supported on a separate support shaft (11). In both axial end surfaces of the support shafts (11) of the roll segments (10) there are coupling means such as an annular projection and an annular recess serving to disengageably connect two adjactent roll segments (10) to each other. The support shaft (11) contains of at least two parts (16, 18) whose mutual disposition is made alterable for the purpose of altering the axial length of the support shaft (11) so much that the coupling means (29, 41) of the facing axial ends of two adjacent roll segments (10) can be engaged and disengaged with each other. This arrangement makes it possible to change a single roll segment from the central area of the segmented roll without the need for disassembling the entire row of roll segments.

An apparatus (10) for producing a fissured, acoustical ceiling panel wherein pins (22) used to fissure the panel are roll applied thereto. The pins (22) are embedded in flexible, resilient polymeric plates (21), and a plurality of the plates (21) are attached to a rotary drum (20) which is used to apply the fissuring pins to the surface of the panel. The invention also includes the method for manufacturing the polymeric plates which are molded and formed with the fissuring pins embedded therein.

Surface finishing or polishing rollers are made by successively mounting disk-shaped surface finishing elements on a spindle rotating in operation. The surface finishing elements are formed of a slitted, preferably rectangular sheet having a continuous portion of material with lamellae protruding perpendicularly therefrom. The slitted sheet is shape-fixed with binder, and the periphery of the protruding lamellae forms an ellipse. The surface finishing elements, each of which comprises an oval disk with lamellae, are mounted inclined on the shaft of the spindle so that the contour of the successively mounted surface finishing elements forms a cylinder in the axial direction of the spindle.

Ein Metallkörper, insbesondere als Walzring, weist einen Grundkörper 2 und einen am Umfang sitzenden Verschleißring 6 auf, wobei der Grundkörper 2 aus einem Material besteht, das einen höheren Wärmeausdehnungskoeffizienten und einen geringeren Verschleißwiderstand als das Material des Verschleißrings 6 hat. Um eine gute Verbindung zwischen Verschleißring 6 und Grundkörper 2 bei geringen Herstellungskosten zu gewährleisten, ist der Verschleißring 6 über eine Lötverbindung 16 mit dem Grundkörper 2 verbunden, wobei Verschleißring 6 und Grundkörper 2 im Verhältnis zueinander derart dimensioniert sind, daß nach der für die Herstellung der Lötverbindung 16 notwendigen Erhitzung von Grundkörper 2 und Verschleißring 6 infolge der Abkühlung radial nach innen gerichtete Schrumpfkräfte von dem Grundkörper 2 über die Lötverbindung 16 auf den Verschleißring 6 übertragen werden.
