Abstract: The present invention concerns a convective system for a dryer installation for a passing web, more particularly paper. The convective system 7 is an assembly of an exterior casing 13 for suction of combustion products with opening 14 towards the web, with a first 15 and second 16 suction ducts sucking the combustion products into the convective system 7. The combustion products coming from the first suction duct 15 are guided through the exterior casing 13 to a mixing and blowing device 17. Cold air 18 is mixed in this mixing and blowing device 17 with the combustion products 19, resulting in a gas mixture with lower temperature 20. The convective system 7 also has an internal casing 21 inside the external casing 13. This internal casing 21 has at least one opening towards the web 22 and has also openings 34 allowing gas flow from the mixing device 17 to the internal casing 21 of said gas mixture 20. Under the internal casing 21, there is also a blowing duct 23.

Abstract: A dryer operable in close proximity to and in series with an inkjet printhead comprises a heat source and an air bearing structure on one side of the predetermined path and having a pressurized air inlet and an air outlet adjacent to the drying position of the receiver medium. Air flow from the air bearing structure outlet forms an air bearing for the receiver medium. A microporous filter positioned at the outlet and being adapted to convert the air flow from the outlet to a diffuse flow, the microporous filter being formed of an inner layer of very fine screen for optimum air diffusion and an outer layer of courser woven screen to add rigidity and protection from scuffing.

Abstract: A wheel includes a peripheral outer wall onto which are sequentially loaded veneer panels. The panels are held in place by cable runs against a heated outer surface of the wheel outer wall. Drying of the veneer panels occurs during wheel rotation. A heated fluid medium such as hot oil flows through an annular chamber of the wheel. A series of inlet conduits supply the annular chamber with the heated medium while return conduits return same to a heat source. Multiple tensioned runs of cable confine each panel in place during wheel rotation. A modified form utilizes a continuous screen for panel retention. A drive system imparts rotation to the wheel by powered components in contact with the wheel periphery. A panel pre-heater and jet dryers are supplemental heat sources.

Abstract: A system and method for fabricating flexible circuits. The inventive system includes an oven and three or more independent tensioners for moving a strip of flex tape therethrough. In total, N tensioners are provided per side. The tensioners provide a cumulative tension force T on the tape and each tensioner applies T/N of the total tension. The tension is applied tangentially in a single plane of the tape along a direction parallel to the longitudinal axis thereof In the illustrative embodiment, the tensioners are sprocket wheels. Eight sprocket wheels are disposed on a supply side of the system and eight wheels are disposed on a take-up side of the system. The sprocket wheels are adapted to engage sprocket holes in the tape. The tape has a sprocket wheel area and a die area. A silicon die is typically bonded to the die area with a suitable epoxy. Copper conductors on the tape communicate electrical signals from a printer or other mechanism to the silicon die.
