摘要:
A hand-held labeller for printing and/or applying self-adhesive labels which adhere as a strip or separately at equal distances on a carrier strip, the apparatus comprising a frame; a supply member mounted with respect to the frame for mounting the carrier strip and labels; a label separation member mounted with respect to the frame; a feed wheel or winding drum mounted with respect to the frame; means for guiding the carrier strip from the supply member by the label separation member and then to the feed wheel; a hand lever so pivotally mounted with respect to the frame that the lever may be pivoted by an operator's hand as the labeller is being held in the hand of an operator; coupling means for coupling the hand lever to the feed wheel to operate the feed wheel each time the hand lever is pivoted and thus advance the carrier strip from the supply member so that the labels are successively separated from the carrier strip at the label separation member and the carrier strip is incrementally wound upon the feed wheel; sensing means for sensing the advancement of the carrier strip a predetermined distance; de-coupling means for de-actuating the coupling means so that the hand lever is de-coupled from the feed wheel in response to the sensing means sensing the advancement of the carrier strip the predetermined distance and thus ensure that the feed wheel advances the carrier strip the predetermined distance each time the hand lever is actuated regardless of the amount of carrier strip wound upon the feed wheel.

A manual, or hand-held labelling device has a printing apparatus and a pivoting lever on which pivoting lever there is a journal pivot pin on which an inking roller can be loosely mounted. For axially securing the inking roller on the journal pivot pin, within the housing of the manual labelling device, there can be at least one raised, guide track in the form of a circular arc, on the housing of the labelling device, and on the side opposite to the pivoting lever. This guide track essentially corresponds to the path of the inking roller on the pivoting lever as the pivoting lever is moved during a labelling operation, and thus supports the inking roller from moving axially off of the pivot pin during movement of the pivoting lever during the labelling operation.

A portable hand-held labelling device can generally have a printing mechanism, which in the case of an embodiment with printing belts and print-side guide wheels, can have the guide wheels rotationally mounted on a shaft which is fixed to the housing. The shaft can be fabricated as a single piece with the housing or a part of the housing, and the free end of the shaft can be centered and laterally fixed in a blind locator in another part of the housing. The shaft can be provided with a longitudinal groove into which a locking strip with a number of guide channels for locking elements, corresponding to the number of guide wheels, can be inserted, and in particular, inserted and locked into place. The locking elements are preferably components of a locking mechanism, which locking mechanism also includes locking locators in the bearing hole of each guide wheel, which locking locators interact with the locking elements to rotationally position the guide wheels on the shaft. The number of locking locators determines the number of defined rotational positions of each guide wheel.

The process for the preparation of 2(3H)-benzothiazolones which are optionally substituted on the benzene ring by reacting a 2-aminobenzothiazole which is optionally substituted on the benzene ring with a diazotization agent in the presence of aqueous hydrochloric acid, if appropriate with addition of a chloride, to give a diazonium chloride, reacting the diazonium chloride directly to give a 2-chlorobenzothiazole, which is optionally substituted on the benzene ring, and hydrolyzing the 2-chlorobenzothiazole, without intermediate isolation, at 120.degree.-200.degree. C. under reaction pressure.

A hand labeling device for imprinting and dispensing self-adhesive labels comprises a housing (110) in which is disposed a printing mechanism (10) movable between a raised inoperative position and a lowered printing position. The printing mechanism comprises a plurality of axially adjacent setting wheels (16) with which type carriers (20) carrying printing types (22) are in a drive connection. A setting shaft (42) extending in the direction of the axis of the setting wheels (16) and connected to the printing mechanism (10) projects outwardly at a housing wall (110a); it is displaceable at a side face of the printing mechanism (10) between an inserted and an extended position and with the aid of said shaft the setting wheels (16) can be adjusted relatively to each other in such a manner that desired printing types (22) on the type carriers (20) move into a printing zone at the printing mechanism (10). Connected to the setting shaft (42) is a stop body (128) which extends parallel thereto and is displaceable with the setting shaft (42) between an extended and an inserted position. In the path which the stop body (128) describes in the extended condition when the printing mechanism (10) is lowered into the printing position a stop edge (126) fixed with respect to the housing is disposed.
摘要:
A printing mechanism is described comprising a housing (12, 14) in which a plurality of type carriers (20) are disposed which are in a drive connection with coaxially disposed setting wheels (16) each having a center bore. In a space formed by the center bores of the setting wheels a setting shaft (42) is axially displaceable and rotatable. By axial displacement the setting shaft can be brought into a drive connection with each of the setting wheels. On the setting shaft an actuating knob (48) is disposed with the aid of which said shaft can be displaced and turned. In the housing a display indicator means (26, 27, 29) is disposed displaceably parallel to the setting shaft; said means is connected to the setting shaft in such a manner that the latter turns relatively thereto but can be displaced axially only jointly therewith. The display indicator means makes it possible to recognize the type carrier which can be adjusted in the respective axial position of the setting shaft. The connection between the setting shaft and the display indicator means is formed by a substantially circular cap ( 64) which is mounted with a hub (62) on the setting shaft and on the edge of which the display indicator means is secured.
