Calender, a machine employed in manufactories to press woollen and silken stuffs, and linens, in order to make them smooth, even, and glossy, also to give them waves, as is done with mohairs and tabbies. This apparatus consists of two thick cylinders or rollers of very hard and well-polished wood, round which the stuffs intended to be calendered are wound. The rollers are then placed cross-wise between two very thick boards, the lower of which serves as a fixed base, while the upper one is moveable by means of a thick screw, with a fastened to a spindle that form-axis : the uppermost board is also laden with large stones of above twenty thousand pounds weight.

Calender. - In the year 1797, the Society for the Encouragement of Arts conferred a reward of 30 guineas on Mr. Edmund Bunting, for his improve-rnent of calender-mills. - The me-D chanism of Mr. B.'s ingenious contrivance being such as cannot be described without delineation, the inquisitive reader will consult the 15th vol. of the Society's " Transactions, " where the whole is illustrated with an engraving. We shall, therefore, only add, that these improvements have received the sanction of able mechanics, who consider them as a valuable acquisition to calenderers; and who, from its cheapness and practicability, conceive them to be worthy of public attention.
