Title: Process of and means for coating of thread-like material with a plastic mass, particularly for dipping candles
IPC: C11C5/02
Filed: 1928-06-29
Abstract: 294,957. Opacki, Z., and Oelwein, L., (trading as Fabryka Swiec, F. Sezemski). June 29, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 3, 1928]. Candles.-In a machine for coating wicks with a plastic material the wick, in endless form, is repeatedly passed through a bath of the coating material and subsequently through a gauge the opening of which is automatically and gradrually increased. The gauge consists of a pair of cooperating discs 1, 2 (Figs. 2 and 3) having circumferential grooves 5 of conical form so that as the discs rotate the aperture enclosed by them at their point of contact increases while remaining circular. In a modification, the grooves may extend more than once round the discs in helical form. The disc 1 is mounted on an eccentric sleeve 9 on the shaft 6, the eccentric being rotated by a spring acting in the direction 11 so as to maintain the discs in contact. The discs are driven by gearing from the drums over which the thread passes and the size of the aperture is indicated on a rotating scale. An adjustable stop mounted on one of the gear wheels automatically stops the machine when a predetermined thickness of coating has been applied to the thread. To ensure gradual acceleration on starting, the elimination of the starting resistances of the motor and the shifting of the belt from the loose to .the fast pulley are effected by the longitudinal movement of a shaft operated by a screw requiring several turns of a handwheel to effect the necessary movement.
