5 Claims.

This invention relates to' improvements in assembly' fixtures adapted for use in assembling and securing together the paper slips of a multiple-slip form.

Multiple-slip forms are used for many purposes and "are of different characters. This invention is adapted for use in assembling and securing together the slips of a form made up'of a broad header sheet anda series of narrower slips attached to the header sheet and to each other along one vertical marginal edge, the first slip projecting or "extending slightly below the lower edge of the "header sheet 'and each additional slip extendingaslight distancebelow the slip nextabove, the header sheet and all the attached slips being secured together inshingle arrangement. The header/sheet and the attached slips must be accurately aligned with each other, and the area of the slips exposed at the 'face of the form must be uniform. Many of these multiple-slip forms are used'in hectographing operations and the exposed portion of each slip receives a line or two of printed matter from the master hectograph sheet. It is obvious, therefore, that the header sheet and the attached slips must be accurately aligned and the exposed portions of the slips must be'uniform' in size. In some instances the slips, after receiving the hectograph impression, are detached from the'header sheet and from each other; It is important, therefore, that the slips be attached to the'header sheet and to each other by adhesive lightly applied along aportion of.- one vertical edge of each slip.

It is the object of this=invention to provide an assembly fixture by means of which the header sheet and the multiplicity of slips may be quickly and accurately assembled and aligned and secin'ed together along onevertical'edge.

In the drawing, Fig. 1 is a planview of the ssembly fixture illustrating the manner of securing the first slip to the header sheet;

Fig. 2 is a similar view of the fixture showing a number of the slips assembled and attached to the header sheet and to each other;

Fig. 3 is a longitudinal vertical sectional View of the assembly fixture taken on the line 3'3 of Fig. 1;

Fig. 4 is a perspective view of the multipleslip form complete; and

Fig. 5 is a detail View of one of the slips with the adhesive applied ready for assembly and attachment to the form.

The header sheet and the attached slips are secured together in reversed position, that is to say, facade-W21.- When .the. form is complete it is removed -from the assembly fixture and reversed in order to' bring it'into face-up position, as shown in Fig. 4.

The assembly fixture consists of a board or edges by the lower edges of the slips.

plate I having an upstanding aligning flange 2 along its left-hand marginal edge. Along the upper edge of the plate I is arranged an up-' standing aligning bar 3 adapted to be engaged by the upper transverse edge of a header sheet. The aligning flange 2 is adapted to be engaged by the left-hand vertical marginal edges of the header sheet and the slips as they are arranged on the fixture. At a suitable distance below-the aligning bar 3 and on the upper face of the plate I is arranged a transversely extending headersheet-aligning bar 4- whose upper edge forms a gag-ingshoulder. This bar terminates a consid erable distance short of the right-hand margin of the plate I. Thisbar 4 is of considerable thickness and forms the lower edge of a large pocket between the aligning lea-r3 and said bar 4 for the reception-of the comparatively large header sheet 5. It is desirable that'thi's bar be of suflicient thickness to permit the stacking in the pocket of a substantial number of header sheets.

Below the header-sheet-aligning bar 4 are arranged a series of slip-aligning and gaging bars 6 whose upper" edges form shoulders which are adapted'tobe engaged by the lower edges of the slips;- Each bar Ii extends transversely of the plate I from thealigning flange 2 and terminates a substantial distance inwardly from the righthand margin of the plate 5. These bars are equal distances apart from each other and from thewbar 4. The distance between the upper edge of one bar and the upper edge of the next bar below it defines the extent of the exposed portions of the attached slips when the form is turned face-up as shown in Fig. 4.. Aligning and gaging-bars 6 project slightly above the upper surface of the plate I and are preferably just thick enough to be engaged along theirupper These bars 6 terminate along a vertical line leaving a smooth, unobstructedsurface onthe plate I at the right-hand ends o-fsaid bars. This flat, unobstructed surface along the right-hand margin of the plate permits the overlapping portions of the header sheet and the slips to lie fiat on the plate and on each other so that theymay be readily secured together by adhesive applied to the slips.

When thefixture is in use a substantial number of the header sheets are placed in the pocket formed by the bar 3 and the gage bar 4,'said sheets being accurately positioned by the aligning flange'Z and by the bars 3 and 4, Adhesive is applied to one of theslips 5 along a portion of its left-hand marginal edge as shown at X in Fig. 5. The adhesive is not applied to that portion. of the left-hand edge of the slip which is to extend belowthe header sheet. The slip with the adhesive applied is then reversed so that the adhesive is then on the under side of the slip at the ill iii)

right-hand marginal edge. The slip, in this position, is then aligned against the flange 2 and the upper edge of the first aligning and gaging bar 6.

The edge of the slip bearing the adhesive is then pressed down at the right-hand margin of the header sheet which is in place between the bars 4 and 3.

by the adhesive. After the attachment of the first slip to the header sheet as described, adhesive is applied to the second slip 5 as illustrated in Fig. 5 and that slip is then reversed, gaged and aligned by the second gage bar 6 and the aligning flange 2. The right-hand margin of this slip, to which the adhesive has been applied, overlies the previously attached slip 5 and is pressed down on the said previously attached slip. The flat, unobstructed marginal portion 1 of the plate I provides a smooth surface against which the right-hand marginal edges of the slips may be pressed to attach them firmly together by the adhesive. This operation of attaching the slips is repeated until the desired number of slips have been secured. When the form is of proper length it is removed from the fixture and reversed so that the attached edges are at the left-hand margin of the form, as illustrated in Fig. 4.

It is of advantage to provide means for stacking a considerable number of header sheets 5 in the pocket between the gaging bar 4 and the aligning flange 3 as that facilitates rapid operation and renders it unnecessary to place a header sheet in the pocket for each multiple-slip form.
