Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a continuous office format and a
Concerning a web with a window for address information, etc.

Office forms, including envelopes and continuous office forms, have long had address windows. An example is U.S. Patent No.
No. 91728 (envelopes with an oblong cut-out window and a transparent cover or envelopes without notches with parts made of transparent material), No. 835850 (envelopes with parts made transparent with paraffin oil or grease) , No. 1438122
No. (an envelope with a roughly rectangular cutout window), no.
No. 3136476 (envelope with a nearly rectangular cutout window),
Seen in Reissue No. 25872 (envelope with roughly triangular cutout window). As shown in these patents,
Oblong and triangular windows within one envelope are marked. However, now windows within serial forms are consistently rectangular with small rounded corners. The technology of continuous office forms with windows has been developed and focused on windows for a variety of reasons, including cost reduction and aesthetic appearance. Window shapes were so standardized that they were considered unchangeable.

In some high speed embossing presses and other continuous form processing equipment, the windowed web and its web are fed through a break in the equipment's protector or the like. The form and web are held in place by vacuum and are moved at speeds from about 2.9 meters (9.6 feet) to about 7.6 meters (25 feet) per minute, or more. about
For paper weighing 14.5 Kg (32 lbs), the typeface and web move well. However, with lighter papers such as 12.7 Kg (28 lb), the windows often got tangled in the protector near the cut, often torn, and often jammed the device.

Such format corruption and jams are extremely costly. When a form is written in sequence with a series of numbers such as salary payment balance, if one form is damaged,
Manual or computerized entry is made to eject the torn form, which requires shutting down the device, removing the torn form, adjusting the device, and restarting the device.

The main objective of the present invention is to overcome these problems caused by format corruption.

While changes in equipment and window panel adhesion are clearly possible in an attempt to eliminate problems with window entanglement and equipment jamming, the inventors believe that simply changing the window type can eliminate the problem. We found that this significantly eliminates As a main aspect, the invention therefore comprises:
An improvement to a web that (a) is continuous in two longitudinal directions along a longitudinal axis, (b) has a series of longitudinally continuous business forms thereon, and (c) has a web of forms on the form. (d) is fed into the first one in two longitudinal directions and is adapted for high speed embossing, so that the first longitudinal The direction is the direction of movement of the web as it is fed and printed. The improvement includes at least two windows extending along each window and generally transverse to the longitudinal axis.
a web with distinct window edges, one of the at least two window edges being a leading window line and the other of the two window edges tracking the leading window edge as the web moves in the direction of motion; This is the trailing fenestra edge. The trailing window edge has a trailing edge side part and a trailing edge center part, and the trailing window edge is curved so that when the web moves in the motion direction, the trailing edge center part tracks the trailing edge side part when viewed from the direction of movement. It's on.

Preferred embodiments of the invention will now be described with reference to the accompanying drawings.

Referring to FIG. 1, a preferred embodiment of the present invention includes a web 10 that is continuous in both directions along a longitudinal axis 12.
Format Web 10, which is an improvement of the continuous office format of
has a continuous set of business forms 14 extending across the form web 10 and longitudinally joined end-to-end across a series of perforation lines 16. Web 10 has feed bands 18,20 along laterally opposed edges 22,24. Bands 18, 20 each have successive rows 26, 28 of spaced apart draw holes.

Each office form 14 is placed in the form 14 at position 31.
A window 30 is defined for displaying address information (not shown) printed thereon. Location 31 is equidistant from continuous longitudinal fold line 32 to window 30 .

Web 10 is fed and printed along axis 12 in a first longitudinal direction 34 that is opposite to a second longitudinal direction 35 . By definition, direction 34 is the direction of motion;
A component of the web 10, ie, a component that precedes other components in the direction of movement 34, is a component that precedes these other components, ie, is a component that precedes with respect to the other components. The other components are therefore subsequent components.

Each window 30 is an area cut from form 14.
The area is covered with a transparent sheet 36 as shown in FIG. Sheet 36 is shaped like Form 14 by the surrounding adhesive.
is glued to. The web 10 and each form 14 have four distinct window edges 40, 42, 4 along each window 30.
It has 4,46. Two edges 40, 42 extend substantially across form 14. other two edges 4
4 and 46 extend substantially longitudinally along the form 14.
The first lateral center 40 is the leading edge of the window, while the opposite lateral edge 42 is the trailing edge. The two edges 44, 46 are opposite side edges of the window.

Edges 40, 44, 46 are geometrically almost perfectly straight lines. Edge 40 is perpendicular to longitudinal axis 12;
One edge 44, 46 is parallel to axis 12. Therefore, edges 44, 46 are perpendicular to edge 40. small rounded or partially circular corners 50,5;
2 joins edges 44, 46 to edge 40 in a smooth transition.

Rim 42 is unique. The edge 42 is curved in the trailing direction. The center 54 of the edge 42 is located at the side 5 of the edge 42.
Track 6,58. Edge 42 is not straight at any point, but is continuously curved throughout its length. Edge 4
The degree, proportion, and amount of curvature of 2 do not substantially change over its length, and the degree of curvature is substantially uniform. The sides 56, 58 are longitudinally equal to each other and approximately
It precedes center portion 54 by 3.2 mm (1/8 inch). Small rounded corners 60, 62 join edge 42 to edges 44, 46 in a smooth transition.

Such a border 42 prevents the printing device from getting entangled,
The problem of clogging is substantially eliminated. This is the only known solution to the problem.

Unless a tip is placed along the edge 42, the bending of the edge 42 (longitudinal distance from the sides 44, 46 to the central portion 54) is limited to 3.2 mm (1 mm) without affecting the degree of freedom from entanglement or otherwise. /8 inches) can be made larger or smaller. Also, bends smaller than 1.6 mm (1/16 inch) are less free from entanglement than those without bends. Edge 4 like a V-shaped notch edge
Points along line 2 are disadvantageous due to die wear.
