Description
~2190~
This invention relates to continuous buslness form assemblies and webs for the same having windows for address infor-mation and the like.
susiness forms, including envelopes and continuous bus-iness form assemblies, have long had address windows. Examples )~ 9 are found in u.S. Patent Nos. 91,728, June 22, ~ - Eastmen, (envelope with oval cut window and transparent cover, or uncut with portion made transpar~nt); 835,~50, November 13, 1906 - Cohn, (envelope with portion made transparent by paraffin-oil or grease);
1,438,122, December 5, 1922 - McCoy, (envelope wi-th generally rec-tangular cut window); 3,136,476, June 9, 1964 - Berkowitz, (env-elope with yenerally rectangular cut window); and Re. 25,872, October 5, 196~ - O'Gorman, (envelope with generally triangular cut window). As shown in these patents, oval and triangular win-dows in single envelopes have been disclosed. However, at present, windows, in continuous business form assemblies are consistently rectangular with small rounded corners. he art of continuous business form assemblies with windows has developed and become focused upon such windows for a variety of reasons, including cost savings and aesthetic appearance. Window shape has become so stan-dardized as to be ignored, and considered unchangeable.
In certain high speed impact printers and other continu-ous business form assembly processing equipment, continuous assem-blies and assembly webs with windows are fed through slits in equipment shields and the like. The assemblies and webs are pos-itioned by air vacuums, and travel at speeds from about 9.6 feet per minute (fpm) and less to about 25 fpm and more. With a paper lZ19015 weight of about 32 pounas, the assemblies and webs travel well.
However, with lower paper weights, such as 28 pounds, the windows frequently snag the shields adjacent the slits, and are frequently torn. The equipment is sometimes jammed.
Such form damage and jamming can be extremely costly.
Where the forms are sequentially marked with serial numbers, as with payroll chec~s, damage to a single form may re~uire that the equipment be stopped, the torn form removed, the machine adjusted and restarted, and manual or computer bookkeeping entries made to avoid the torn form.
A principal object of this invention was to overcome the problems caused by such form damage.
While equipment changes and window panel gluing changes are obvious possibilities for attempting to eliminate the problems of window snagging and equipment jamming, this invention proceeds with the discovery that a mere change of window shape substantially eliminates the problems. Thus, in a principal aspect, the inven-tion is an improvement in a web, the web (a) being continuous in both of two longitudinal directions along a longitudinal axis, (b) having a series of business forms thereon, the series being continuous in the longitudinal direction~, (c) defining a series of cut windows in -the web on the forms, the series of windows being continuous in the longitudinal directions, and (d) being adapted to be fed and high speed impact printed in a first of the two longitudinal directions, the first longitudinal direction thereby being a direction of travel of the web during feeding and printing. The improvement is of the web having at least two dis-~19V15 tinct window edges along each window extending generally trans-verse to the longitudinal axis, one of the at least two window edges being a leading window edge and the other of the two window edges being a trailing window edge trailiny the leading window edge when the web is moved in the direction of travel. The trail-ing window edge has trailing edge sides and a trailing edge center, the trailing window edge being bowed away from the direction of travel such that the trailing edge center trails the trailing edge sides when the web is moved in the direction of travel.
The preferred embodiment of the invention will be des-cribed in relation to the accompanying drawing consisting of twofigures as follows:
FIGURE 1 is a plan view of a preferred continuous busin-ess form assembly web; and FIGURE 2 is an enlarged plan view of the area encircled by line 2 in FIGURE 1.
Referring to FIGURE 1, the preferred embodiment of the invention is an improvement in a continuous business form assembly of a web 10 being continuous in both directions along a longitu-dinal axis 12. The assembly 10 has a continuous series of busin-ess forms 14 which extend transversely across the assembly 10 andare joined longitudinally end-to-end across a series of perfor-ation lines 16. The assembly 10 has feed strips 18, 20 along transversely opposite edges 22, 24. The strips 18, 20 include continuous rows 26, 28, respectively, of spaced tractor holes.
Each form 14 defines a window 30 for displaying address information tnot shown) to be printed on the form 14 at a location s 31. The location 31 is equidis-tant with the window 30 ~rom a continuous, longitudinal fold line 32.
The assembly 10 is fed and printed in a first longitud-inal direction 34 along the axis 12, away from the second longit-udinal direction 35. By definition, the direction 34 is the dir-ection of travel, and components of the assembly 10 which precede other components in the direc~ion of tr~el 34 lead such other components, or are, in relation to the other components, leading components. The other components are, then, trailing components.
Each window 30 is an area cut from a form 14. The area is covered with a transparent sheet 36 as in FIGURE 2. The sheet 36 is adhered to the form 14 by an encircling adhesive 38. The web 10 and each form 14 have, along each window 30, four distinct window edges 40, 42, 44, 46. Two of -the edyes 40, 42 extend gen-erally transversely across the form 14. The other two edges 44, 46 extend generally longitudinally along the form 14. The first transverse edge 40 is the leading edge of the window, while the opposite transverse edge 42 is the trailing edge. The two edges 44, 46 are opposed side edges of -the window.
The edges 40, 44, 46 are substanti~lly completely straigh-t, geometrically. The edge 40 is perpendicular to the longitudinal axis 12, while the edges 44, 46 are parallel to the axis 12. Thus, the edges 44, 46 are perpendicular to the edge 40.
Small, rounded, or partially circular corners 50, 52 join the edges 44, 46 to the edge 40 in a smooth transition thereform.
The edge 42 is unique. The edge 42 is bowed in the trailing direction. The center 54 of the edge 42 trails the sides 56, 58 of the edge 42. The edge 42 is nowhere straight, but con-tinuously curved throughout its extent. The degree, rate or amount of curvature of the edge 42 does not substantially vary across its extent; the degree of curvature i5 substantially uniform. The sides 56, 58 are longitudinally even with each other, and lead the center 54 by about one-eighth inch. Small, rounded corners 60, 62 join the edge 42 to the edges 44, 46 in smooth transitions.
With such an edge 42, the problem of printer snagging and jamming is substantially eliminated. This is the only known solution to the problem.
It is believed that so long as no points are loca-ted along the edge ~2, -the bow (longitudinal distance from the sides 44, 46 to the center 54~ of the edge 42 could be greater or less than one-eighth inch without affect on freedom from snagging or otherwise. It is also believed a bow of less than one-sixteenth inch would not be any more free of snagging than no bow. Points along the edge 42, as with a V~cut edge, are disfavoured due to die wear.
The preferred embodiment is now described. To partic-ularly point out and distinctly claim the subject matter regarded as invention, the following claims conclude this specification.
