ROTATABLE CHUCK FOR GLASS TUBES

Chucks for glass tubes should be designed so that, on the one hand, they grasp the glass tube gently so that the tube is not destroyed, and, on the other hand, so that they hold it securely enough so that a proper processing of the glass tube is possible. This causes a degree of technical complexity...

Zusammenfassung:	Chucks for glass tubes should be designed so that, on the one hand, they grasp the glass tube gently so that the tube is not destroyed, and, on the other hand, so that they hold it securely enough so that a proper processing of the glass tube is possible. This causes a degree of technical complexity which enlarges the dimensions of the chuck and leads to a narrow diameter range for the clampable glass tubes. For other diameter ranges, the chucks have to be changed. The chuck according to the invention has a wide diameter range with small outside dimensions. The chuck has clamping jaws which can be moved radially with respect to its longitudinal axis and has a distance from the longitudinal axis determined by a pressure sleeve, which is connected to the clamping jaws by a forced guidance device. The forced guidance forms an angle of 30 DEG to 60 DEG , and preferably 45 DEG , with respect to the longitudinal axis. The chuck is used to hold glass tubes in a machine for producing vials.
