MATCH PACKET v Filed July 21, 193s f L ZY' Q..

MATCH PACKET .John R.' Nolan. Larchmont, N. Y., assignor to The'Diamond Match Company, New York,` N. Y., a corporation of Delaware Application July 21.19311, semi No. :gaat

'I'his invention relates to match packets and the manufacture thereof, having reference especially to the type of book matches wherein the end of the paperboard cover remotefrom the match heads is constructed to present a flat friction bearing surface of substantial width, as illustrated in Letters Patent of the United States No. 2,101,111 dated December '1, 1937.

'I'he object of the invention is to provide for l such book matches a friction bearing surface of such character that the liability of the outwardly bowing or "peaking of the surface by opposing transverse pressure on its longitudinal edges during the repeated normal use of the book is obviu ated, particularly when the book cover is of relatively thin or soft paperboard, as will be hereinafter described and claimed.

In the drawing- Figure l is a perspective view of a book 'of 20 matches embodying my invention, the ignition material being omitted to show the transverse corrugations of the rectangular end of the cover, such corrugations being somewhat magnified for clearness. v

g5 Fig.l 2 is a similarview with the ignition material applied to the corrugated surface.

Figs. 3 and 4 are partial longitudinal vertical sections, enlarged, of the books shown in Figs.' 1 and 2, respectively.

30 Fig. 5 is a transverse vertical section, as on the line 6-5 of Fig. 4.

Fig. 6 is a sectional elevation showing` roll devices for corrugating the cover material.

Fig. 7 is a transverse vertical section through 35 the rolls, as on the line 1 1 of Fig. 6, showing in addition, means for progressively applying ignition material to the corrugated surface, and also means for pre-moistening such surface.

The form of match book illustrated in the draw- 40 ing comprises one or more match cards or combs A and a flexible cover B therefor. Each card comprises a row of match stems I headed at their outer or free ends and frangibly attached at their inner ends to the uncut base portion II.

Thel .45 cover consists of an elongated rectangular strip of exible paperboard formed and folded to em (ci. 20s-29) such fold and wall portion and imparts thereto a flaring formation effective to support an'd brace ,the longitudinal edges of the panel, as described in Patent No. 2,101,111 aforesaid.

In the improved match bool: herein illustrated the end panel I4 of the cover/ material is formed throughout its length with relatively small transverse'corrugations I6, and the outer corrugated surface thus produced is coated and covered with ignition material I'Iwhich fills vthev grooves or m valleys of the corrugations and presents a smooth outer frictionsurface.A The transverse corrugations reinforce the panel and the embedded ignittion material, when hard, aords a multiplicity of cross braces which contribute to the transverse reinforcement and stiffening of the panel, thereby obviating liability of the outward bowing or distortion of the ignition surface -through the application of opposing transverse `pressure to its longitudinal edges during the normal service of the match book, as previously mentioned. Moreover, the transverse embedded portions of the ignition material eifectually lock the material to the panel, and also present an eilicient match striking surface should the outer face of the material become worn from extended use. v

In carrying out my invention the corrugations are progressively formed in the cover material by .means comprising, preferably, correspondingly fluted rolls between the mating peripheral surfaces of which the cover material is fed, the ign/ition material being thereafter applied to the corrugated surface.

In Figs. 6 and 'I the mating fiuted rolls I8 are shown as mounted on parallel transverse shafts I9 having meshing gears 20, one of the shafts being driven from a suitable source of power. These' shafts have their bearings in a standard (or standards) 2| rising from a bed 22 which sustains the table 23 on which the sheets of cover 4,0 material (C) are supported, such sheets being delivered in succession' to'and between the rolls. The uted rolls I8 are formed with lateral smooth portions 24 which bear against the 'upper and lower surfaces of the sheet in a manner to feed 4'5 and prevent distortionv of the body of the. sheet during the corrugating operation. Rearwardly of the rolls I8 and in operatlverelation to the path of the corrugated surface of the cover sheet is aroll 25,' or other suitable element, which ap- 50 plies the ignition material to the progressing corrugatedportion of the sheet. The sheets thus formedv and .treated are subsequently subdivided into covers of pro shape and size for assoc ation with the match cards or combs. I 55 ademas the lonsitudinal edes oi' said end portion, seid end portion being transversely corrugated, and said ignition material covering the outer corrugated surface and being embedded in the grooves thereof.

2. A cover for match packets of the type described, comprising a sheet of flexible paperboard oldable transversely of the sheet to provide a flat rectangular end portion, said portionvbeing transversely corrugated throughout its length and exteriorly coated with ignition material embedded in the grooves of the corrugations.
