' z claim. (ci. zeef-'46) 'I'he present invention relates to cellular en- "velopes for housing strips of material to protect them in handling and transporting, and to the resulting packaged material.

Present trends in house construction have led to the wholesale supplying of trim" strip with paint, lacquer or other iinishig material already applied in `selected colors or styles. It is important that these be packed separately to protect each strip, and that the packing be eective and inexpensive. The usual practice in putting such strips into the hands of the consumer, is for the manufacturer to supply bundles of a. dozen or more standard lengths to a lumber yard or like merchant. vThe latter stocks the material in the original container, which is the sub- :lect of this invention. As there is demand for one or more strips less than a bundle, the merchant seversthebundle into two or more portions, providing bundles with one or more cells containing the number ofstrips desired.

One object of the invention is to provide a cellular envelope for strip material which is inexpensive, for the purpose of'protecting the material from damage to its surface.

Another object of the invention is to provide such a multicellular envelope which is readily severable into one or more cellular envelopes of one or more cells, without removal of the strip material housed in the envelope.

Another object of the-invention is to provide simple and practical protection for these predecorated trim elements, not only in transit to the dealer in original packages but also from the dealer in split packages to the .10b in the field so that' removal lof a length from its protecting cell does not occur until the applicator is ready, to nt and place it in its nal position on the job.

Another object of the invention is the forming of a structure of considerable resistance to deformation by placing a number ofvlengths in a continuous multicellular envelope, then rolling or folding the filled cells together so as to secure the rigidity of a group of elements bound together, v which would not be possible if the elements were discontinuously wrapped. v

Another object of the invention is to provide a convenient means of placing and presenting the various lengths ofthe predecorated trim .always in the same order and position so that no doubt exists as to what length each cell contains. If wrapped separately this would not be possible.

Another object of the invention is to provide an envelope which whentightly rolled or folded, maintains the elements making up the structure in rigid relative position so that no slipping and sliding can take place-in transit with consequent rubbing `and marring. This would not bethe case if the lengths were separately wrapped.

'I'he Iforegoing objects and advantages are s readily obtained by useof the form and structure shown in the accompanying drawing to illustrate the Ypreferred form oi the invention.

Fig. 1 represents a plan view of an envelope 10- lled with strips, with one end folded over.

Fig. 2 is a cross-sectional view ofthe envelope of Fig. 1, taken on the folding line 2 2, and showing the ends of the strip material.

Figs. 3 and 4 respectively represent a folded 15 and a rolled bundle of the iilled envelope as prepared for shipment.

Fig. 5 is a cross-section of a wrapped bundle of Fig. 3 or Fig. 4 showing an end protection for the bundle and wrapper. 20

The envelope may be made'inexpensively by running two webs of paper I0 and II from sup-v plying rolls, over adhesive rolls to apply on one web spaced strips of adhesive, such as sodium silicate, glue, asphalt, etc. Then the second web 25 is united to the rst web to provide a duplex web of layer- IllI and layer II united by edge strips of adhesive I2 and I3, and intermediate strips of adhesive I4. The spacing between the strips is .varied according to the nature of the strip mate- 3 rial I5 to be housedin the separate tubular cells I6. The width of the adhesive strips I2, I3 and Il may vary as desired, but is such as to assure a holding union between the two webs I0 and'II. 'I'he intermediate adhesive strips I4 are prefer-A 35 ably made suiciently wide to permit suitable. weakening of the duplex web, by scoresor by perforations I8, so that each cell as a unit may be separated from the whole to provide a. cellular or tubular envelope for one strip of material.l 4 The duplex web, made as above described may 4 be stocked in a roll if desired, and besevered into lengths according to the length of material to be housedtherein. Preferably the severed length is longer than the strip material to provide free ends 20 and 2l to befolded in as end flaps on the folding lines 22 and 23, which lie' approximately at the ends of the strips Ii. When the naps 20 l and 2I are so folded in. they are pulled taut to, bind the contents end-to-end. The naps are preferably glued down, 'so that when a severed section of a iilled envelope for example one cell, is handled, .there is no opening-up ofy the'v end flaps, with consequent slippage of envelope and contents. Thus the surface is protected to the y very time of taking it from its envelope by destroying thesame.

The filled nat envelope may be consolidated as in Fig. 3 to a substantially rectangular form, or rolled as in Fig. 4. be used to seal the bundle and are preferred to tying with rope or cord, which may possibly mar corners of strips I6 by local pressure. However.

' any Well known means of securing the bundle may be used. The form of Fig. l3 is preferred, because in severing the bundle into sections, it is not necessary to move or disturb the entire bundle, as can be readily seen by inspection-of the drawing.

Ordinary kraft paper is suitable for the envelope, but one or both of the webs I0 and Il may be creped paper, to give pliability and toughness. or may be Waterproofed paper for protection against water, or a duplex paper, or any combination desired. A machine-glazed paper is preferred with the glazefsidel disposed to thev inside ofthe cells. This is more important where glazed material is used in the pockets.

The uniting strips I2, I3 and I4 need not be.

adhesive but may represent stitching or any other material or structure uniting the two Webs to dene a tubular cell.

Additional protection is desired when bundles may be shipped long distances, or may be handled considerably. It is important to glue the bundle greater rigidity than asingle wrapped strip of equal length. This is accomplished by securely binding the consolidated bundle into a rigid unit, as shown in Fig. 5. A consolidated lled envelope as in Figs. 3 and 4 is shown at 26. This is wrapped round and round in an ordinary manner with strong paper or fabric 2l, which forms at least a tubular envelope. Over the end of the bundle is placed a. solid protective plate, such as a piece of wood or artificial board 28. Over this plate,

and over the tubular wrapping is slipped a boot or cap 29 designed for a snug t, with a lap joint if desired to secure the snug nt. Sealing tape 30 is placed over the end 'of the boot 2S and on the 5 wrapper 21 beyond the boot; Thus, if the bundle Adhesive paper strips 25 may is slipped along, a smooth surface is presented.

minimizing tearing the boot oi! the end of the bundle.

The present invention provides a bundle of individually packaged iinished strips which are sealed from factory to consumer, with' permissible division of the bundle without exposure of lany length. By placing a plurality of lengths so that ends terminate at the folding line of the flaps, a neat bundle is formed. VPreferably the lengths are as long as the bundle, but smaller lengths may be placed end to end in one cell.'

By the simple expedient of inserting all strips in the same order of facing and direction, thefuser may take lengths successively, as needed,.and is not required to twist and turn them, as would be the case if each was individually wrapped, and the items handled as miscellaneous items, and not as a single unit.

Various modifications are contemplated as fallbundle; and a cap over each end plate extending over and including within it the wrapper.

2. A bundle of elongated strip material comprising an envelope having a plurality of parallel tubular cells; elongated strips of material to be protected mounted in said cells; said envelope being capable of being laid out flat, but in the bundle with its cells lled, being consolidated by superimposing one portion on another; a plate` over each -end of the consolidated bundle, and means holding the plates and consolidated bundle as a rigid unit.
