摘要： A method and apparatus is provided for heating vinyl composition tiles which are then amenable to cutting with a knife along complex contours without damaging the tiles. A stack of heating trays are located within a protective housing. The housing is supported on wheel means for ease of transport about the worksite and has one open side so that tiles can be loaded onto each of the trays. A discrete electrical heating element heats each tray and tile to a uniform temperature which renders the tile sufficiently elastic to be cut along any desired contour without fracturing. The trays are spaced appropriately so that tiles can be individually seized for cutting by the installer. The combination of the number of trays and the heating element's heat transfer capability enables an installer to repeatedly seize a sufficiently heated tile, re-load the vacant tray, and then seize another heated tile from the next sequential tray on a cyclical, sustainable basis. For added convenience, it is preferable that each tray be provided with a mechanical tile extractor and that the housing contain a cold tile storage compartment.
