Machine for digital printing on tape
A machine for digital printing on tape, which comprises a frame that supports elements of entraining at least one tape along an advancement path and is provided with at least one printing assembly, which comprises at least one ink-jet printing head; downstream of the printing assembly, along the advancement direction of the tape, there is at least one assembly for drying the inks applied to the tape; the drying assembly comprises a temperature-adjustable drum for supporting and entraining the tape, adhesion elements adapted to allow the retention in adhesion of the tape on the outer lateral surface of the drum, and hot air emitter elements which face at least one portion of the outer lateral surface of the drum.
METHOD FOR DRYING A SUBSTRATE, DRYER MODULE FOR CARRYING OUT THE METHOD, AND DRYER SYSTEM
Methods for drying a substrate. The methods include the following steps: (a) emitting infrared radiation towards a substrate moving through a process space using an emitter unit comprising at least one inflated emitter, (b) generating at least two process gas streams of a process gas directed towards the substrate, (c) drying the substrate by the action of infrared radiation and process gas on the substrate, and (d) extracting moisture-laden process gas from the process space via an extraction duct, forming an exhaust air stream leading away from the substrate. To specify a drying method which is reproducible and effective and leads to an improved result, in particular in terms of homogeneity and speed of drying of the substrate, the at least two process gas streams are guided to the infrared emitter before they act on the substrate, and an exhaust air stream is spatially assigned to each process gas stream.
Dryer, printer, and treatment liquid applicator
A dryer for drying a drying object includes a hot air generator to generate hot air to be blown onto the drying object, a contact heater to contact and heat the drying object, and a controller to control a heating temperature of the contact heater and a temperature of the hot air. The controller controls the heating temperature of the contact heater to be above a first predetermined temperature from a start of generation of the hot air by the hot air generator until the temperature of the hot air reaches a second predetermined temperature.
Heated roller, in particular for a textile printer, and textile printer comprising this roller
A heated roller, in particular for a textile printer, comprising: a pair of stationary supports, an elongated tubular element located between said stationary supports and rotatably carried by said stationary supports about a longitudinal axis, a stationary infrared lamp extending inside said tubular element and having opposite ends supported by said stationary supports, a lamp support device extending between said stationary supports inside said tubular element and supporting the infrared lamp between said stationary supports, and an elastic device which applies an elastic tension to said lamp support device between said stationary supports in the direction of said longitudinal axis.

Infrared-heated air knives for dryers
Systems and methods are provided for enhanced dryers for printing systems. One embodiment is an apparatus that includes a dryer for a continuous-forms printing system. The dryer includes heating elements located within an interior of the dryer that radiate infrared energy onto a web of printed media as the web travels through the interior, and an air knife that is interposed between the heating elements. The air knife includes a shell that directly absorbs infrared energy from the heating elements and also defines a passage for air to travel through the air knife onto the web. The shell directly absorbs infrared energy from each heating element that would otherwise overlap on the web with infrared energy from another heating element.
