The invention provides a web winding device for attaching a leading edge of a web to a take-up roller positioned at an end of a transport path. A guide device is rotatable around the roller axis of the take-up roller from a first to a second angular position. The first angular position is positioned adjacent the end of the transport path and the second angular position is positioned in a space between the transport path and the take-up roller. The guide device is arranged for:

Web winding device

A printer is provided for forming a phase change inkjet image on a print substrate. The printer includes a sheet transport unit for advancing the sheet along a print station. The sheet transport unit includes a sheet support platen, a sheet attraction mechanism and a feed mechanism. The sheet support platen includes a print surface for supporting a contact side of the print substrate. The sheet attraction mechanism is arranged for attracting the print substrate to the print surface. The feed mechanism is arranged for advancing the print substrate in a transport direction over the print surface, wherein the feed mechanism is arranged upstream of the print surface. The print station includes a print head assembly, the print head assembly being arranged for providing ink droplets for forming the phase change inkjet image on a process side of the print substrate, the print substrate being arranged on a print area of the print surface, the process side being opposite to the contact side. The print surface has an average surface roughness Ra being in the range of 1 micron to 4 micron.

Printer for forming a phase change inkjet image

The present invention relates to a printer for forming a phase change inkjet image. The printer comprises a platen comprising a print surface, an advancing mechanism adapted for moving a print substrate in a transport direction over the print surface and a print station adapted for providing the phase change inkjet image on a first surface of the print substrate in a print area of the print surface. The advancing mechanism comprises a plurality of feed nips, said plurality of feed nips being arranged upstream of the print surface. Each of said plurality of feed nips comprising a feed roller which comprises a main rotational axis, wherein each main rotational axis of said plurality of feed nips is aligned with respect to each other in a second direction, which second direction is substantially perpendicular to the transport direction. The advancing mechanism further comprises a star wheel. Said star wheel is arranged in between two adjacent feed nips in the second direction and faces a support surface. Said star wheel in printing operation is arranged in rolling contact with the first surface of the print substrate upstream of the print area in the transport direction of the print substrate and is adapted for urging the print substrate towards the support surface.

A magnet knife assembly for a toner developing device including a ferromagnetic strip held between like poles (N) of two permanent magnets such that a knife edge portion of the strip projects outwardly beyond the two magnets and is subject to a magnet force that tends to urge the strip in a direction in which the knife edge projects further out of the magnets, wherein the length of the strip is selected such that a portion of the strip opposite to the knife edge is subject to a magnetic force that at least counterbalances said magnetic force on the knife edge portion.
