Systems and methods for adjustable interlacing of drying rollers in a print system. One system is an apparatus that includes first rollers that conduct heat from a heat source, and dry a web of print media as the web travels over a front side of the first rollers in a first direction. A last roller of the first rollers turns the web in a second direction. The apparatus also includes second rollers disposed a distance above the first rollers and that transport the web in the second direction. The apparatus further includes a movement mechanism that reduces the distance between the second rollers and the first rollers to cause the second rollers to occupy spaces between the first rollers so that the web traveling in the second direction contacts a back side of the first rollers to further dry the web.

An apparatus for removing fluid, such as condensate, from the inside of a rotating cylinder 10. The apparatus comprises a syphon shoe 50 proximate to an inside surface 35 of the rotating cylinder 10. The syphon shoe 50 is connected to a syphon pipe 28. The syphon shoe 50 further comprises two opposing circumferential openings 51, 52 and a divider 60. The two opposing circumferential openings 51, 52 are disposed substantially parallel to the direction of rotation of the rotating cylinder 10. The divider separates the opposing circumferential openings 51, 52 and extends radially from the end of the syphon shoe 50.

A dryer for conveying and drying an object to be dried, the dryer includes a conveyor including a first path and a second path along which the object to be dried is conveyed, a conveyance direction of the second path being different from a conveyance direction of the first path, and a blower to blow air onto the object to be dried. The blower includes a first air outlet that faces the first path and blows the air onto the object to be dried conveyed along the first path, and a second air outlet that faces the second path and blows the air onto the object to be dried conveyed along the second path.

A conveyor for printer includes, a first guide, a second guide disposed separately from the first guide, a third guide disposed between the first guide and the second guide, the first guide, the second guide, and the third guide defining a conveyance path along which a medium is conveyed, and a loading guide movable to guide the medium between the first guide and the second guide. The third guide is movable between a first position and a second position. The third guide presses the medium to the first guide and the second guide at the first position and is separated from the medium at the second position. The loading guide is disposed at a guiding position to guide the medium and is disposed at a retracted position retracted from the guiding position in response to the third guide disposed at the first position.

Systems and methods for concentric arrangement of web conditioning modules in a dryer of a printing system. In one embodiment a dryer includes a drum, first rollers positioned in an arc around the drum to define a web path between an entrance of the dryer and the drum, and second rollers positioned along the arc between the first rollers and the drum that reverse the web path between the drum and an exit of the dryer. The dryer further includes first web conditioners positioned along the arc and beyond the first rollers from the drum that direct energy toward a portion of the web path that is between the entrance of the dryer and the drum. The dryer further includes second web conditioners positioned along the arc between the second rollers and the drum that direct energy toward a portion of the web path that wraps around the drum.

Systems and methods for evenly heating a drum dryer of a print system. In one embodiment, the dryer is configured to rotate about an axis oriented in a lateral direction, to receive a radiant energy source disposed inside the drum that extends between each lateral end of the drum in the lateral direction, and to receive a reflective assembly inside the drum that includes an inner portion and an outer portion. The inner portion surrounds the radiant energy source and removably attaches the reflective assembly to a lateral end of the drum. The outer portion extends from the inner portion in a radial direction of the drum that is perpendicular to the lateral direction. The outer portion includes a reflective surface that reflects radiant energy from the lateral end to the central portion of the drum in contact with the web.

A thermal roller (1) includes: a cylindrical body (2) extending along a longitudinal direction (X-X), the cylindrical body (2) including at least one inner tubular element (3) and at least one outer tubular element (4) that is concentrically arranged around the inner tubular element (3), the inner tubular element (3) includes an outer diameter d and the outer tubular element 4 includes an inner diameter D, being D>d; two hubs (6), each arranged at one end of the cylindrical body (2); at least one heat-exchange chamber (10) realized between the inner tubular element (3) and the outer tubular element (4). The roller includes: a coating layer (11) for the inner tubular element (3) made of plastics, and at least one helical channel (13) between the coating layer (11) and the outer tubular element (4). The helical channel (13) is realized at least partially in the coating layer (11).
