Claims
- 1. A method of assembling a stamp printing mechanism using a type carrier set,
- the type carrier set comprising a plurality of endless type carriers which at their outer surface in consecutive fields carry print types, the type carriers being disposed so as to be parallel adjacent each other in a predetermined order for use in the stamp printing mechanism, adjacent ones of the type carriers being connected together by shearable connecting webs, the type carriers being endless bands,
- the stamp printing mechanism having two housing halves, of which one supports rotatably and axially displaceably a setting shaft which can be brought by at least one driver member into a drive connection with setting wheels which in turn are in a drive connection with the type bands for adjustment thereof, a stack of setting wheels being placed about the stack of setting wheels such that a portion of the inner peripheral surface of each type band comes into engagement with a portion of the outer peripheral surface of a setting wheel, the stack of setting wheels being inserted with the type carrier set into one of the housing halves, and after assembly of the housing halves the driver member being brought by axial displacement of the setting shaft consecutively into a drive connection with in each case one setting wheel; and by turning of the setting shaft via the drive connection through the driver member and the drive connection between the respective setting wheel and the associated type band, the connecting webs on said type band are sheared off.
- 2. A type carrier set for a stamp printing mechanism comprising a plurality of endless type carriers which at their outer surface in consecutive fields carry print types, the type carriers being disposed so as to be parallel adjacent each other in a predetermined order for use in the stamp printing mechanism, adjacent ones of the type carriers being connected together by shearable connecting webs;
- a setting shaft and a plurality of setting wheels which are selectively rotatable by said setting shaft, and wherein said connecting webs are sufficiently frangible to permit breaking of said connecting webs on a selected one of said type carriers upon application of a manual torque to said setting shaft applied to a corresponding one of said setting wheels.

Parent Case Info
This application is a continuation of Ser. No. 871,832, filed 6/9/86, now abandoned.
The invention relates to a type carrier set according to the preamble of claim 1 and to a method of assembling a stamp printing mechanism using such a type carrier set.
In stamp printing mechanisms the print types are disposed in consecutive fields on the outer surface of type carriers. In every stamp printing mechanism there is a type carrier set consisting of a plurality of individual type carriers. A type carrier set contains as a rule several identical type carriers with which the digits 0 to 9 and symbols such as a full stop, a dash or a stroke can be printed, and one or more further type carriers with which currency information such as "DM" or the like can be printed. The type carriers are generally kept available in storage boxes and for assembling the stamp printing mechanism the type carriers are removed from the storage boxes and assembled to give the type carrier set necessary for the printing mechanism. The individual type carriers of the set may then be inserted consecutively individually into the printing mechanism to be assembled. The individual insertion of the type carriers into the printing mechanism to be assembled is a time-consuming operation in which moreover there is a danger of the various types of type carriers being mixed up so that with a finished printing mechanism the desired imprints cannot be produced because the type carriers for example have been inserted in the wrong order.
The invention is based on the problem of making a type carrier set of the type outlined in such a manner that from the start up to installation in a stamp printing mechanism it is easy to manipulate and saves time.
The problem underlying the invention is solved with the features set forth in the characterizing clause of claim 1. The method according to the invention for assembling a stamp printing mechanism using the type carrier set according to the invention is set forth in the characterizing clause of claim 5.
In the type carrier set according to the invention the individual type carriers are not separated loosely from each other but hang together on connecting webs which can be sheared off. The entire type carrier set can therefore be treated as a unit and as such also inserted on assembly into the appropriate housing half of the stamp printing mechanism. Since the type carriers in the carrier set are already arranged in the order necessary for use in the stamp printing mechanism it is not possible to mix up the individual type carriers and this facilitates the assembly.
Further advantageous developments of the invention are characterized in the subsidiary claims.
