Abstract

Abstract A continuous-motion decorating machine for cylindrical containers is provided with a removable and replaceable overvarnish unit subassembly. The overvarnish unit includes control and transfer metering rolls which supply a film of varnish to an applicator roll. The latter, in turn, applies the varnish as a protective coating over decorations on the outside surface of spindle-mounted cylindrical containers. Paralleling the axes for the applicator roll and spindle is accomplished by tilting the sub-frame of the overvarnish unit relative to the main frame of the machine. Each paralleling and pressure or gap adjustment at the nips between the respective rolls, as well as at the nip between the applicator roll and container being decorated, is accomplished without upsetting adjustments at the other nips.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 331 words
Apparatus for operating on cylindrical containers, said apparatus including a main frame, a coating station on said frame, and conveyor means on said frame including spindles for carrying cylindrical containers along a feed path extending through said coating station whereby containers moved along said feed path receive a filmlike coating at an applicator nip in said coating station, said coating station having a coating mechanism including adjacent control and transfer metering elements forming a metering nip therebetween to receive a coating substance and produce a controlled thickness film of this substance on said transfer element, a transfer roll constituting said transfer element, an applicator roll for applying a coating of this substance to decorated containers, said applicator roll positioned adjacent said transfer roll and forming a transfer nip therebetween whereat the applicator roll receives the film from the transfer roll, first support means to which the control element is mounted, second support means to which the transfer roll and said first support means are mounted, and third support means to which the applicator roll is mounted, said third support means being adjustably mounted with respect to said main frame to adjust said applicator nip without operatively disturbing the transfer or metering nips, said second support means being adjustably mounted with respect to said main frame to adjust said transfer nip without operatively disturbing the metering or applicator nips, said first support means being adjustably mounted to said second support to adjust said metering nip without operatively disturbing the transfer or applicator nips, said coating mechanism also including a sub-frame interposed between said main frame and said second and third supports, means mounting said second and third supports to said sub-frame, adjustable means removably securing said sub-frame rigidly to said main frame whereby said coating mechanism is removable and replaceable as a subassembly, said adjustable means being constructed for operation which tilts said sub-frame relative to said main frame to parallel the cylindrical axis of the applicator roll to the spindle axes.
Claim 2
Dependent Claim 331 words
Apparatus for operating on cylindrical containers, said apparatus including a main frame, a coating station on said frame, and conveyor means on said frame including spindles for carrying cylindrical containers along a feed path extending through said coating station whereby containers moved along said feed path receive a filmlike coating at an applicator nip in said coating station, said coating station having a coating mechanism including adjacent control and transfer metering elements forming a metering nip therebetween to receive a coating substance and produce a controlled thickness film of this substance on said transfer element, a transfer roll constituting said transfer element, an applicator roll for applying a coating of this substance to decorated containers, said applicator roll positioned adjacent said transfer roll and forming a transfer nip therebetween whereat the applicator roll receives the film from the transfer roll, first support means to which the control element is mounted, second support means to which the transfer roll and said first support means are mounted, and third support means to which the applicator roll is mounted, said third support means being adjustably mounted with respect to said main frame to adjust said applicator nip without operatively disturbing the transfer or metering nips, said second support means being adjustably mounted with respect to said main frame to adjust said transfer nip without operatively disturbing the metering or applicator nips, said first support means being adjustably mounted to said second support to adjust said metering nip without operatively disturbing the transfer or applicator nips, said coating mechanism also including a sub-frame interposed between said main frame and said second and third supports, means mounting said second and third supports to said sub-frame, adjustable means removably securing said sub-frame rigidly to said main frame whereby said coating mechanism is removable and replaceable as a subassembly, said adjustable means being constructed for operation which tilts said sub-frame relative to said main frame to parallel the cylindrical axis of the applicator roll to the spindle axes.
Claim 3
Dependent Claim 37 words
Apparatus as set forth in claim 1 in which there is a control roll constituting said control element, said control and transfer rolls having relatively rigid cylindrical surfaces and said applicator roll having a yieldable cylindrical surface.
Claim 4
Dependent Claim 71 words
Apparatus as set forth in claim 1 also including additional means for moving the transfer roll to adjust its cylindrical axis parallel to the cylindrical axis of the applicator roll, said second support being constructed so that with said cylindrical axes of said rolls parallel adjustment of said second support will bodily move the transfer roll relative to the applicator roll without disturbing parallelism between said cylindrical axes of said rolls.
Claim 5
Dependent Claim 17 words
Apparatus as set forth in claim 3 in which the additional means comprises a single eccentric means.
Claim 6
Dependent Claim 91 words
Apparatus as set forth in claim 4 in which there is a control roll constituting the control element, further means for moving the control roll to adjust its cylindrical axis parallel to the cylindrical axis of the transfer roll, said first support being constructed so that with the cylindrical axes of the control and transfer rolls parallel the axes of these rolls will remain parallel during adjustment of said first support and the control roll will move bodily relative to the transfer roll, said further means comprising a single eccentric means.
Claim 7
Dependent Claim 48 words
Apparatus as set forth in claim 5 in which there is a drive gear on said main frame through which driving power is delivered to the rolls of said coating station said second support being mounted on a support axis coAxial with the axis for said drive gear.
Claim 8
Dependent Claim 83 words
Apparatus as set forth in claim 3 in which there is a control roll constituting the control element, further means for moving the control roll to adjust its cylindrical axis parallel to the cylindrical axis of the transfer roll, said first support being constructed so that with the cylindrical axes of the control and transfer rolls parallel the axes of these rolls will remain parallel during adjustment of said first support and the control roll will move bodily relative to the transfer roll.
Claim 9
Dependent Claim 17 words
Apparatus as set forth in claim 7 in which the further means comprises a single eccentric means.
Claim 10
Dependent Claim 48 words
Apparatus as set forth in claim 1 in which there is a drive gear on said main frame through which driving power is delivered to the rolls of said coating station, said second support being mounted on a support axis coaxial with the axis for said drive gear.
