Definitions
- the invention relates to a thermoregulator for a printing form placed around a printing form cylinder for waterless offset printing according to the preamble of the first claim.
- waterless offset printing uses a special silicone layer to keep the non-printing areas of the printing form free of color. This property of the silicone surface breaks down above a certain temperature, which is around 35 ° C. The optimal operating temperature is 25 ° C or below.
- a blow box installed instead of the conventional dampening roller system distributes the cold air over the entire width of the printing form cylinder to the printing form.
- the blow box is connected to a thick air supply hose, which takes over the transport of cold air from a refrigeration system installed next to the printing press to the printing form cylinder of the printing unit.
- thermoregulator for the printing form.
- the object of the invention is to provide a thermoregulator for a printing form placed around a printing form cylinder for waterless offset printing, which makes it possible to blow on the printing form by means of tempered air which is produced directly in the area of the printing form cylinder.
- any conventional offset printing machine can be converted in a simple manner by removing the dampening application rollers, hanging the blowing case according to the invention into the printing machine and then connecting it to existing dampening solution cooling devices.
- the machine can be prepared for the normal offset process at any time. Additional cooling systems or other units in addition to the printing press are no longer required, since the existing dampening solution cooling devices are already integrated in conventional printing presses for offset printing. Since the printing form cylinder heats up only slowly during operation and the printing form is also isolated by washers, no great cooling capacity is required for temperature control.
- a blow box 3 which has blow-out openings opposite the printing form cylinder 1 in order to blow it at a certain angle with the blowing air.
- the blow box 3 extends over the entire width of the printing form cylinder 1. It is preferably installed in the offset printing machine instead of the conventional roller dampening unit.
- At least one fan 4 is first provided, which is mounted inside the blow box 3.
- a cooler 5 is provided in the direction of flow of the blown air, which cooler 6 from outside half of the blow box 3 is supplied with a coolant 7, preferably with water.
- a cooling coil 11 in the form of finned tubes having a cooler 5 is suitable.
- the cooling coils 11 are provided with a water inlet line 10 and a water outlet line 9 of a refrigeration system 6, preferably in the form of a water cooling device, e.g. of a commercially available fountain solution cooling unit.
- a sensor 12 which detects the temperature of the coolant 7 and a controller 8 are provided which regulate the cooling of the cooler 5 as a function of the temperature of the coolant 7.
- a thermostatically controllable throttle valve is suitable, which is provided in the water drainage line 9.
