An apparatus for applying a sleeve on a pipe comprises a dispenser for wrapping material and guides which define the path followed by the dispenser around the pipe. The guides are held on the pipe so that they are immovable as the sleeve is formed.

An apparatus for wrapping wrapping material on an elongated cylindrical substrate to form a sleeve on the substrate, the apparatus comprising: (a) at least one guide for placement around the circumference of the substrate and holding means for securely holding the guide in place around the substrate

An apparatus for wrapping wrapping material on an elongated cylindrical substrate to form a sleeve on the substrate, the apparatus comprising: (a) at least one guide for placement around the circumference of the substrate and holding means for securely holding the guide in place around the substrate so that (i) the guide is in plane perpendicular to the longitudinal axis of the substrate, (ii) the guide is immovable axially on the substrate, and (iii) the guide is immovable circumferentially around the substrate; and (b) a wrapping material dispenser comprising (i) means for supporting a roll of the wrapping material so that the wrapping material can be dispensed from the roll, (ii) at least one roller for pressing dispensed wrapping material against the substrate, and (iii) tracking means for tracking the guide around the substrate for dispensing wrapping material around the pipe to provide a sleeve, any overlapping portions of the sleeve being substantially coincident. A method for forming a sleeve on an elongated cylindrical substrate comprising the steps of: (a) placing a pair of guides around the circumferential periphery of the substrate with the guides parallel to each other and spaced apart; (b) selecting a dispenser comprising (i) means for supporting roll of wrapping material so that the wrapping material can be dispensed from the roll, (ii) at least one roller for pressing dispensed wrapping material against the substrate, and (iii) tracking means for tracking the guide around the substrate; (c) securing the guides to the substrate so that the guides are in a plane perpendicular to the longitudinal axis of the substrate and so the guides are (i) immovable axially on the substrate and (ii) immovable circumferentially around the substrate; and (d) moving the dispenser around the circumference of the substrate with the tracking means tracking the guides to provide a sleeve, any overlapping portions of the sleeve being substantially coincident.
