Abstract
Abstract An adjustable squeegee supporting device of a rotating screen in a sheet material printing machine of the type wherein the squeegee is supported by a bar, the two ends of which are connected respectively to two exterior fixed points through two links and is subjected to the action of position adjusting means. One of the ends of the links is rigidly connected to the bar and the other is pivotally mounted on an axis along the line of contact of the screen with the material. The inclination of the links may be adjusted through two rods connected to two simultaneously adjustable disk-cranks. The free edge of the squeegee is applied against the screen by means of an inflatable tube interposed between the squeegee and its supporting bar.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
207 words
A device for adjustably supporting a flexible squeegee within a rotating horizontal cylindrical screen of a sheet material printing machine, said screen engaging the material to be printed along a nip, said squeegee having a securing edge and a free operative edge, said device comprising: a supporting bar extending axially through said cylindrical screen and longer than the axial length of said screen, said supporting bar having end portions, said securing edge of said squeegee being secured to said supporting bar, fixed support means, two links located at either end of said screen, the end portions of said supporting bar being respectively rigidly secured to one end of one of said links, the other end of each of said links being pivotally mounted to said fixed support means on an axis which is in alignment with said nip, supporting bar adjusting means connected to said fixed support means for adjusting the angular position of said two links relative to the radial plane containing said nip, said operative edge of said squeegee always being located substantially along said nip, and means for biasing said squeegee to cause said operative edge of said squeegee to press the inner surface of said screen at said nip with a predetermined pressure.
Claim 2
Independent Claim
207 words
A device for adjustably supporting a flexible squeegee within a rotating horizontal cylindrical screen of a sheet material printing machine, said screen engaging the material to be printed along a nip, said squeegee having a securing edge and a free operative edge, said device comprising: a supporting bar extending axially through said cylindrical screen and longer than the axial length of said screen, said supporting bar having end portions, said securing edge of said squeegee being secured to said supporting bar, fixed support means, two links located at either end of said screen, the end portions of said supporting bar being respectively rigidly secured to one end of one of said links, the other end of each of said links being pivotally mounted to said fixed support means on an axis which is in alignment with said nip, supporting bar adjusting means connected to said fixed support means for adjusting the angular position of said two links relative to the radial plane containing said nip, said operative edge of said squeegee always being located substantially along said nip, and means for biasing said squeegee to cause said operative edge of said squeegee to press the inner surface of said screen at said nip with a predetermined pressure.
Claim 3
Dependent Claim
85 words
A device as defined in claim 1, wherein said supporting bar adjusting means comprises: two crank-disks each having a crank-pin, two further links, each further link having one end pivotally connected to the crank-pin of one of said crank-disks and the other end pivotally connected to one end of said supporting bar, a horizontal shaft parallel with said squeegee rotatably mounted on said fixed support means, said crank-disks being rigidly secured to said pivoting shaft, and means for adjusting the angular position of said shaft.
Claim 4
Dependent Claim
52 words
The device as defined in claim 1, wherein said biasing means comprises an inflatable air tube eXtending lengthwise between said supporting bar and said squeegee, said inflatable air tube engaging said supporting bar and a longitudinal area of said squeegee located between said securing edge and said operative edge of said squeegee.
