Abstract
Abstract A drying arrangement located in a drying station and intended for drying printed material includes a material-conveying path (10), preferably arranged to convey the material through the print drying station, and further including one or more drying and/or curing means (19). The print drying and/or curing means (9) is, or are, arranged to operate intermittently. A control means (12) for controlling the intermittent operation of the means (9) is arranged to activate the drying and/or curing means over a period of time in which the wet coating in the material is located adjacent the drying and/or curing means (9). There is also included a multi-ink printing or multi-coating printing arrangement which comprises a plurality of sequentially arranged and interconnected printing machines (1, 2, 3) having intermediate drying arrangements (4 and 5). The printing arrangement has a single, intermittently operating gripping system (10) which is common to all printing machines and drying arrangements in the printing arrangement. A gripper (10a) in one printing machine (1) and a gripper (10a') in an adjacent drying arrangement (4) form a sealing means for sealing the infeed and outfeed openings of the drying arrangement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
213 words
An arrangement including at least one drying station for drying print deposited on material received from a printing machine, said drying station comprising conveyor means for conveying material along a path through the drying station, said conveyor means including a plurality of gripping bars which are spaced apart according to a predetermined path-length, said gripping bars extending transversely with respect to said path, a source of radiation for print-drying, and control means for intermittently operating said plurality of gripper bars and for intermittently energizing the source of radiation for drying said print during a period of time when wet print coating said material is adjacent said source of radiation, wherein said drying station is provided with a hood positioned about said source of radiation, said hood having an infeed opening and an outfeed opening for receiving and discharging, respectively, printed material, said infeed opening and said outfeed opening being spaced apart according to said path-length, said plurality of gripper bars being driven intermittently such that members of said plurality of gripper bars are registered with said infeed opening and said outfeed opening when said source of radiation is energized for drying said print so that said members substantially prevent the passage of light and heat through said infeed opening and said outfeed opening.
Claim 2
Dependent Claim
213 words
An arrangement including at least one drying station for drying print deposited on material received from a printing machine, said drying station comprising conveyor means for conveying material along a path through the drying station, said conveyor means including a plurality of gripping bars which are spaced apart according to a predetermined path-length, said gripping bars extending transversely with respect to said path, a source of radiation for print-drying, and control means for intermittently operating said plurality of gripper bars and for intermittently energizing the source of radiation for drying said print during a period of time when wet print coating said material is adjacent said source of radiation, wherein said drying station is provided with a hood positioned about said source of radiation, said hood having an infeed opening and an outfeed opening for receiving and discharging, respectively, printed material, said infeed opening and said outfeed opening being spaced apart according to said path-length, said plurality of gripper bars being driven intermittently such that members of said plurality of gripper bars are registered with said infeed opening and said outfeed opening when said source of radiation is energized for drying said print so that said members substantially prevent the passage of light and heat through said infeed opening and said outfeed opening.
Claim 3
Dependent Claim
79 words
The arrangement according to claim 1, wherein said source of radiation comprises at least one mercury lamp which generates ultra-violet radiation, said at least one mercury lamp being controlled by a choke device and an igniter element included in said control means, said at least one mercury lamp being energized by said control means in an operational sequence wherein the igniter element provides an ignition period of sufficient duration to cause ignition of said at least one mercury lamp.
Claim 4
Dependent Claim
43 words
The arrangement according to claim 2, wherein the control means energizes said at least one lamp for a predetermined time period so that energy radiated by said at least one lamp exceeds a lowest energy emission to the material, per unit of area.
Claim 5
Dependent Claim
21 words
The arrangement according to claim 3, wherein the level of energy radiated per unit of time is selected solely for skin-curing.
Claim 6
Dependent Claim
20 words
The arrangement according to claim 1 wherein the level of energy radiated per unit time is selected solely for skin-curing.
Claim 7
Dependent Claim
63 words
The arrangement according to claim 1, wherein said arrangement is a multi-coating printing arrangement which includes a plurality of sequentially arranged printing machines which are coupled together, and intermediate drying stations between adjacent printing machines, wherein said multi-coating printing arrangement includes a single, intermittently operating gripping bar system which is common to all printing machines and drying stations in the multi-coating printing arrangement.
Claim 8
Dependent Claim
38 words
The multi-coating printing machine arrangement according to claim 6, wherein a gripper bar in one printing machine and a gripper bar in an adjacent drying station register with the infeed and outfeed openings in said adjacent drying station.
