Abstract

Apparatus for makeready of a business forms press having an unwind apparatus (12) for supporting a rolled web (20) of material and having a plurality of rotatable members in spaced alignment defining a path for the web and arranged to perform operations on said web such as printing (22, 23), perforating (45), numbering (35), punching (40, 42) or slitting, wherein the members are rotated in synchronism and are adjustable laterally and/or circumferentially with respect to the web path, is disclosed as comprising markings (90) and scales (110) establishing a reference position in the unwind apparatus for the rolled web and further devices (125, 230, 250, 270, 297, 327) establishing separate side reference positions for each of said rotatable members which has a lateral adjustment with respect to the unwind reference position, and further markings and scales (128, 222, 247, 272, 298, 308) establishing a circumferential reference position for each of said rotatable members with respect to each other. A coordinate layout system (62, 64, 68) for preparing a makeready job sheet is also provided with marks corresponding to the reference positions and scales in dimensions corresponding to said scale devices. A job sheet having dimensional settings is prepared with the layout system, using a representation of the desired product, whereby measurements are provided for lateral and circumferential adjustment of the adjustable rotatable members using their respective scale devices and the settings for the rotatable members can be accomplished with precision to minimize their adjustment once the web is threaded through the press and a run is started.

Claims6

Dependent claims

In a web printing press for printing business forms, including

an unwind station having a mechanism for supporting a roll of web material within a range of adjustment width-wide of said press,
at least one print station having means including rotary cylinders for printing form information on the web,
a numbering station including numbering machine means operable to print a number on each of the printed forms,
a a punch station including marginal punch unit means for forming a series of marginal holes along the printed forms,
a cross perforator station including rotating perforating blade means for making a transverse discontinuous line of perforation across the printed web for separation of the individual forms,
a drive connected to said stations to withdraw the web material from the roll and to rotate said cylinders and operate said numbering machine means, said marginal punch unit means, and said cross perforating blade means all in synchronsim:
the improvement comprising
said punch station and/or said cross perforator station having a rotary zero reference position relative to said drive,
means at one of said stations establishing a lateral zero reference position of the web and a means for indicating displacement of the web from the lateral reference position,
adjustment mechanisms at plural ones of said stations for adjusting the rotary displacement of the means included in said stations relative to said rotary reference position,
adjustment mechanisms at plural ones of said stations for adjusting the lateral displacement of the means included in said stations relative to said lateral reference position,
and coordinated indicated means coupled to each of said adjustment mechanisms to indicate the respective lateral or rotary zero positions and the respective lateral or rotary adjustments,
said adjustment mechanisms and indicator means constituting a coordinate layout system enabling precise alignment of each of said stations of the press from coordinate instructions at the beginning of makeready of the press.

A web press for manufacturing business forms, comprising:

an unwind station having rotatable support means adapted to receive and support a roll of web material;
at least one printing station having printing means for performing printing operations;
a numbering station adapted to receive numbering means for performing numbering operations;
a punching station adapted to receive marginal punching means for performing marginal punching operations;
a perforating station adapted to receive rotating perforating blade means for performing cross perforation operations;
said unwind, printing, numbering, punching and perforating stations defining a path for web material to be fed therethrough for performing printing, numbering, punching and perforating operations thereon;
drive means connected to said unwind station for withdrawing web material from a roll and connected to the other said stations to enable said other stations to perform said printing, numbering, punching, and perforating operations in synchronism;
means at one of said stations providing a rotary reference position relative to said drive;
means at one of said stations providing a lateral reference position for said web path;
adjustment means at each of said stations for adjusting the rotary displacement of the operating means of such stations from said rotary reference position at the beginning of press makeready prior to printing and in accordance with predetermined instructions correlated to said rotary reference position;
adjustment means at each of said stations for adjusting the lateral displacement of the operating means of such stations from said lateral reference position at the beginning of press makeready prior to printing and in accordance with predetermined instructions correlated to said lateral reference position;
and
an indicator means coupled to each of said adjustment means for displaying the displacement of each of said operating means relative to said rotary or lateral reference positions, respectively;
said adjustment mechanisms and indicator means constituting a coordinate layout system enabling precise alignment of each of said stations of the press from coordinate instructions at the beginning of makeready of the press.
