Definitions
- the invention relates to a blanket device in particular for a printing machine of the type with two blankets mounted side by side on a printing cylinder.
- the blankets are fixed at their two ends in grooves made in the peripheral face of the cylinders.
- the grooves are offset by 180 ° or 90 ° so as to minimize the beats created by the passage of the grooves.
- Machines of this type have the advantage of being of simple construction and of allowing a lower cost of manufacturing presses than that of presses of the "satellite" type.
- they have the great disadvantage that the paper is not supported continuously as on the counter cylinder of a satellite press. This can result in a longitudinal fold of the paper which can cause it to break or cause difficulty in folding the paper and this all the more if several strips of paper go in the same folder.
- the present invention aims to provide a blanket device which overcomes the drawbacks which have just been stated.
- a blanket device is characterized in that it includes means for supporting the paper to be printed in the junction zone of the two juxtaposed blankets. According to one of the characteristics of the invention, the adjacent lateral ends of the two blankets are cut along a line which is not parallel to the direction of travel of the paper.
- FIG. 1 is a schematic top view of a blanket device according to the present invention.
- Figures 2 and 5 are plan and developed views of other embodiments of a blanket device according to the invention.
- the reference numbers 1, 2 and 3 designate respectively a strip of paper to be printed and two blankets axially juxtaposed with a printing machine, for example double width, of printing configuration blanket / blanket and in turn eight inking.
- the two blankets 2, 3 are mounted side by side on a printing cylinder not shown.
- the two ends of each blanket are fixed in a groove formed in the outer peripheral surface of the printing cylinder, in a manner known per se.
- the grooves bear the reference 4.
- the two grooves 4 for fixing the two blankets 2, 3 are angularly offset by 180 or 90 °, so as to minimize the beats created by the passage of the grooves.
- the adjacent lateral ends 6, 7 of the two blankets are cut along a line which is not parallel to the direction of travel of the paper, indicated by the arrow F.
- This shape of the lateral ends of the blankets can be obtained in various ways, some of which are shown.
- Figures 2 and 3 show trapezoidal or double trapezoidal shapes of the adjacent ends of the blankets.
- the cutting line is broken while Figure 5 shows a wavy cutting line. All the embodiments of the cutouts of the adjacent ends of the blankets 2, 3 have in common that the junction zone indicated at 8, in which the paper 1 is not supported by the blankets 2, 3 is relatively small compared to the periphery blankets.
- Blanket cutting can be done easily using a computer-controlled cutting table.
- the cutting table ensures perfect parallelism of the cuts of the two adjacent edges of the two blankets.
- the cutting of the two blankets will take account of the angular offset of the grooves of the blankets, the edges having to be assembled so as to constitute a constant space between the two blankets mounted on the same cylinder.
- the invention is particularly and advantageously applicable to newspaper printing machines in the blanket against blanket configuration.
- the grooves for anchoring the blankets, formed in the cylinder may not extend as far as the cut end of the blanket, that is to say, in general, be shorter than in FIG. 1.
