Abstract
A machine or apparatus for installing resilient or elastomeric strip seals of indefinite length in expansion joints in, for example, highways and bridges. The machine includes an open, upper frame connected to a lower frame supported at its four corners by four freely rotating wheels. A pair of clamping pistons on the lower frame includes rollers which are adjusted to engage one face of the expansion joint. A toothed wheel or blade rotates about an inclined axis and is powered by a motor through a speed reducing gearbox. The toothed wheel engages the seal and forces it into a channel on the side of the expansion joint opposite to the side engaged by the rollers.
