Abstract
Abstract A machine for printing on articles having two inking stations each with a printing block and a carriage carrying a squeegee movably mounted for sweeping over and inking the printing block and a single printing station common to the two inking stations. A transfer unit with two transfer arms carrying transfer pads is pivotally mounted for reciprocating movement parallel to the stations and axial reciprocating movement perpendicular to the stations, and the inking stations are arranged symmetrically with respect to a plane passing through the pivotal axis of the transfer unit and the central zone of the printing station. Each transfer pad may print the same or different colors. With twocolor printing the same color order can be maintained with a high printing rate. The transfer arms may also be provided with a plurality of said transfer pads for simultaneously printing on a plurality of objects.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
252 words
A machine for printing on articles, comprising a first inking station, a second inking station, each inking station having a printing block and a carriage with inking means and wiping means mounted for sweeping movement over its associated printing block, a single printing station common to both said inking stations and having a support for articles to be printed, and a transfer unit including a pair of arms each carrying a transfer pad, means mounting the transfer unit for rotational movement between a first travel position in which one of the transfer pads is above one of the inking stations and the other transfer pad is above the printing station and a second travel position in which the other transfer pad is above the second inking station and the one transfer pad is above the printing station, means connecting the transfer unit with each of the carriages for movement therewith, the inking means at one of the stations and the wiping means at the other of the stations being operative during the displacement from the first travel position to the second travel position, and the wiping means at the one of the stations and the inking means at the other of the stations being operative during the displacement from the second travel position to the first travel position, and means mounting the transfer unit for axial reciprocating displacement from each of said first and second travel positions of the transfer pads to corresponding operative positions at the respective stations, and vice versa.

Dependent Claim
252 words
A machine for printing on articles, comprising a first inking station, a second inking station, each inking station having a printing block and a carriage with inking means and wiping means mounted for sweeping movement over its associated printing block, a single printing station common to both said inking stations and having a support for articles to be printed, and a transfer unit including a pair of arms each carrying a transfer pad, means mounting the transfer unit for rotational movement between a first travel position in which one of the transfer pads is above one of the inking stations and the other transfer pad is above the printing station and a second travel position in which the other transfer pad is above the second inking station and the one transfer pad is above the printing station, means connecting the transfer unit with each of the carriages for movement therewith, the inking means at one of the stations and the wiping means at the other of the stations being operative during the displacement from the first travel position to the second travel position, and the wiping means at the one of the stations and the inking means at the other of the stations being operative during the displacement from the second travel position to the first travel position, and means mounting the transfer unit for axial reciprocating displacement from each of said first and second travel positions of the transfer pads to corresponding operative positions at the respective stations, and vice versa.
Claim 3
Dependent Claim
21 words
A machine as claimed in claim 1, wherein said transfer arms are located substantially at 90* with respect to each other.
Claim 4
Dependent Claim
38 words
A machine as claimed in claim 1, wherein the means connecting the transfer unit with the carriage comprises a crank-rod system provided between each transfer arm and the carriage of the associated inking station, for driving said carriage.
Claim 5
Dependent Claim
40 words
A machine as claimed in claim 3, wherein the crank-rod system comprises a crank-rod pivotally connected at one end of its associated carriage and carrying at the other end a pin received in a slot in its associated transfer arm.
Claim 6
Dependent Claim
19 words
A machine as claimed in claim 4, wherein said pin has a flanged member adjustably mounted in the slot.
Claim 7
Dependent Claim
31 words
A machine as claimed in claim 3, further comprising guides for guiding said carriage above the associated printing block and an ink reservoir mounted at the side of said printing block.
Claim 8
Dependent Claim
35 words
A machine as claimed in claim 6, wherein said inking means and wiping means comprises two squeegees mounted on said carriage, one for inking the printing block and the other for wiping the printing block.
Claim 9
Dependent Claim
71 words
A machine as claimed in claim 7, wherein each said squeegee is carried by a fork member movably mounted on said carriage perpendicularly to said printing block, the fork members being coupled together by a rocking lever pivotally mounted about an axis intermediate said fork members, and limit stops for limiting rocking movement of the rocking lever in the vicinity of the ends of the path of movement of the carriage.
Claim 10
Dependent Claim
23 words
A machine as claimed in claim 8, wherein at least one of said squeegees is adjustable in position, perpendicular to said printing block.
Claim 11
Dependent Claim
22 words
A machine as claimed in claim 9, wherein at least one of said squeegees is inclined with respect to said printing block.
Claim 12
Dependent Claim
32 words
A machine as claimed in claim 1, wherein each transfer arm is provided with a plurality of transfer pads for simultaneously printing on a plurality of objects in said single printing station.
