US 5,117,610 A · Methods and apparatus for printing and collating materials from multiple webs

Abstract

Methods and apparatus for printing and collating multiple webs of materials, particularly for use in creating personalized direct mail materials, are disclosed. The invention includes a single, highly flexible press having components capable of being driven at unequal speeds to account for different sizes of insert materials and their associated envelopes. Operating a single press in this manner reduces the amount of waste web material which otherwise would be present. The press similarly includes novel collating and inserting apparatus whereby each outgoing envelope is effectively formed around the "insertable" materials. Control mechanisms and verification systems associated with the press additionally maintain any personalized materials in registration, permitting a single press to produce the entire direct mail piece from multiple webs with minimal waste.

Dependent claims

A method for collating materials from a plurality of webs, comprising the steps of:

a. printing an image on a first web;
b. severing a portion of the first web;
c. applying adhesive to a second web;
d. adhering the second web to a third web while inserting the severed portion of the first web therebetween;
e. printing an image on a fourth web;
f. maintaining the images on the first and fourth webs in registration while independently controlling their tension;
g. severing a portion of the fourth web;
and
h. inserting the severed portion of the fourth web between the second and third webs as the second and third webs adhere.

A method for printing and collating materials from a plurality of webs, comprising the steps of:

a. feeding paper from a first web into a printing line;
b. feeding paper from a second web into the printing line;
c. feeding paper from a third web into the printing line;
d. printing images on the first web using a first offset printing unit, coupled to a drive means operating at a first speed, operating at a second speed which may, but need not, be equal to the first speed;
e. printing images on the second web using a second offset printing unit, coupled to the drive means, operating at a third speed unequal to the second speed for printing different numbers of images per unit length of the first and second webs;
f. printing an image on the third web;
g. fixing the printed images on the first, second, and third webs;
h. imaging registrable information on the first web using at least one variable ink jet printer;
i. dividing the first web into first and second ribbons, each containing registrable information imaged thereon;
j. maintaining the registration of the first and second ribbons;
k. dividing the second web into third and fourth ribbons;
l. passing the second and third ribbons through independent tension controlling means;
m. placing the second and third ribbons adjacent one another and severing portions of them simultaneously;
n. conveying the severed portions of the second and third ribbons to nip rollers;
o. conveying the first ribbon and the third web to the nip rollers;
p. applying adhesive to the fourth ribbon and conveying it to the nip rollers;
q. passing the first and fourth ribbons, third web, and second and third severed ribbon portions through the nip rollers so that the first and fourth ribbons adhere to form series of pockets in which second and third severed ribbon portions and at least a portion of the third web are captured, each pocket including registrable information on the first ribbon corresponding to the registrable information on the second ribbon;
and
r. severing portions of the adhered first and fourth ribbons.

16 more elements

A printing line for printing and collating materials from a plurality of webs, comprising:

a. a first feeding mechanism for feeding paper from a first web into the printing line;
b. a second feeding mechanism for feeding paper from a second web into the printing line;
c. a third feeding mechanism for feeding paper from a third web into the printing line;
d. a first offset printing unit coupled to the printing line for printing images on the first web;
e. a drive motor coupled to the first offset unit for operating the unit at a first speed;
f. a second offset printing unit coupled to the printing line for printing images on the second web;
g. a speed change mechanism coupled to the drive motor and the second offset unit for operating the unit at a second speed unequal to the first speed for printing different numbers of images per unit length of the first and second webs;
h. means for printing an image on the third web;
i. at least one dryer and one chill unit coupled to the printing line for fixing the printed images on the first, second, and third webs;
j. at least one variable ink jet printer coupled to the printing line for imaging registrable information on the first web;
k. a slitting mechanism coupled to the printing line for dividing the first web into first and second ribbons, each containing registrable information imaged thereon;
l. means for maintaining the registration of the first and second ribbons;
m. means for dividing the second web into third and fourth ribbons;
n. means for independently controlling the tension of the second and third ribbons;
o. means for placing the second and third ribbons adjacent one another and severing portions of them simultaneously;
p. a pair of nip rollers forming part of the printing line;
q. a belt conveyor for conveying the perforated second and third ribbons to the nip rollers;
r. means for conveying the first ribbon to the nip rollers;
s. means for applying adhesive to the fourth ribbon and conveying it to the nip rollers;
t. means for passing the first and fourth ribbons, third web, and second and third severed ribbon portions through the nip rollers so that the first and fourth ribbons adhere to form series of pockets in which the second and third severed ribbon portions and at least a portion of the third web are captured, each pocket including registrable information on the first ribbon corresponding to the registrable information on the second ribbon;
and
u. a cutting mechanism coupled to the printing line for severing portions of the first and fourth ribbons.
