Patent CA-2257549-A1 (CA)
Inventor: BLOECHLE WALTER
IPC: G01D5/347
Filed: 1999-01-05
Abstract: The present invention represents a new method for reading the position of an encoding mask. This method significantly increases the resolution without increasing the encoding mask resolution. An array of light cells is placed at one side of an encoding mask and consists of four elements. An array of photocells is placed on the other side and also consists of four elements. All cells in a photocell array are exposed in cell-by-cell order with 50% overlapping. The distance between cells in a light cell array is equal to the distance between cells in a photocell array. A photocell array is aligned with a light cell array. The output signal from a photocell array is made by summarizing the signals of each cell. The output signal from each cell is proportionate to the amount of the cell's surface being exposed.   An encoding mask is designed in such a manner, that the output signal from a photocell array is sine-wave shape analog signal. The phase shift of analog signal defines absolute position of an encoding mask above a photocell array.
Patent CA-2258331-A1 (CA)
Title: Variable cutoff offset press unit
Inventor: ERBSTEIN BOB
IPC: B41F13/44
Filed: 1999-01-19
Abstract: A fixed cutoff press is adapted to a variable cutoff press while maintaining thesize of the blanket cylinders. A plate cylinder is mounted on a frame and includes a plate cylinder sleeve and a blanket cylinder is mounted on the frame, includes with a gapless blanket cylinder sleeve. The gapless blanket sleeve contacts the plate cylinder sleeve at a first nip. The press has an impression plate mounted on the frame in the case of a non-perfecting press or an identical, mirror image assembly of plate and blanket cylinders in the case of a perfecting press. A material to be printed passes through a second nip. Inkers are provided for transferring an ink film to the plate cylinder sleeve, the ink pattern being subsequently transferred to the blanket cylinder sleeve at the first nip and the ink pattern being subsequently transferred from the blanket cylinder sleeve to the material to be printed at the second nip. The press also includes drivers to drive in rotation the plate cylinder and drivers to drive in rotation the blanket cylinder. A controller is provided for controlling each of the drivers so that the surface speed of the sleeve of the plate cylinder and the surface speed of the blanket cylinder sleeve are equal at the first nip. The plate cylinder sleeve is variable, whereby a length of an image to be printed is varied proportionally to the variable outer diameter while maintaining the outer diameter of the gapless blanket cylinder sleeve constant. Accordingly, since the size of the blanket is fixed and offset presses presently require changing plates for each job, changes in cutoff are made in a manner similar to today, i.e. plates but not blankets are changed for each job. Ideally, the residual ink on the blanket, once the image is transferred to the web, is small enough that a secondary image will not appear on the web. The invention also provides for the inclusion of a blanket washer or scrapper, which continually removes the residual ink and recirculates it through the ink train to avoid any secondary images.
