The present invention relates to a dryer for treating a moving printing web in a rotary printing press with gas, having a nozzle body. The dryer according to the invention is characterized in that the nozzle body has at least one opening for the exit of heated gas and has at least one opening for recirculating the cooled gas.

Sensor units that includes a power source, a communication interface, and a sensor coupled to the power source and the communication interface. The sensor is calibrated to connect the power source to the communication interface upon an occurrence of a condition in an appliance. The sensor, thereby, permits the communication interface to transmit data indicating the condition to a computing device. Methods, systems, and apparatus, for monitoring such sensor units.

The present invention provides a conveyor belt tracking system for a dryer having a web of a mesh material having a protrusion extending along the length proximal one lateral edge and above a flat surface and a first generally cylindrical roller having a three-tiered slot for receiving the protrusion and two flanking shallow tracks for receiving base flanges.

A treatment-liquid application device includes a treatment liquid applicator to apply a treatment liquid to an application target object to which a black liquid and a color liquid other than the black liquid are applied. The treatment liquid applicator applies a greater amount of the treatment liquid per unit area to at least a region to which the color liquid is applied than a region to which the black liquid is applied.

A web drying apparatus, comprises: two blower units which are arranged vertically between an upper dry path and a lower dry path disposed below the upper dry path and at least partially overlap each other when viewed from a vertical direction. One blower unit disposed on an upper side, the other blower unit disposed on a lower side. The lower end part of the one blower unit deviates from the upper end part of the other blower unit in the horizontal direction and protrudes to be lower than the upper end part in the vertical direction.

The apparatus (100) comprises several stations for treating fabric (10). For example, a cleaning station (20) is provided that is arranged to remove loose debris from the fabric and move the fabric in a continuous motion through the cleaning station. A treatment station (40) is then arranged to receive the fabric from the cleaning station and to transfer treatment fluid to the fabric in a treatment zone. Finally, a drying station (50) is arranged to receive the fabric from the treatment station and to dry the fabric in a drying zone. Advantageously, the treatment station is arranged to transfer the treatment fluid by spraying the treatment fluid under pressure onto a side of the fabric.
