In belt chamfering machines, the glass sheet being machined is gripped and conveyed during the machining (chamfering) of its edge between two facing portions of two belts. The rear belt extends downwards more than the front belt as it has to provide a support for the sheet at or in proximity to the edge being machined. Small sheets cannot be machined by known machines of this type because they would not be adequately gripped between the two belts. To obviate this drawback, the invention provides for the rear belt to be able to be adjusted in height so as to vary the downward projection of said belt relative to the front belt. At the same time, the position of the conveyors on which the sheets rest before and after machining can be adjusted to the same degree. |
