My invention relates to improvements in processes for prod ucing wrapped paper packages from loose .unpacked materials and unfolded wrappers, the process of forming the wrapper, packing the goods, and closing the wrapper being a continuous operation.

In attempting to produce packages of various materials,as, for example, prunes-- considerable difliculty is experienced if the effort be made to put the prunesinto a flexible wrapper afterthe wrapper has been formed into the shape of a bag or the like. My process consists in producing the complete package of Wrapped material by a series of processes I or steps in which the formation of the covering is carried on during and. as part of the process of filling the same.

I have shown my improvement illustrated, as it were, diagrammatically in the accompany ing drawings, for it will be readily understood that various kinds of machines and devices may be employed and that-many, if not all, of the several steps. might in a way be carried on by hand or by hand devices. I have invented a machine for the purpose of effecting these processes, but do not desire to limit the process to the use of any particular machine,

In the accompanying drawings, Figure 1 is a cross-section through a former consisting of several folding parts. Fig. 2 is a plan view of the same. Fig. 3 is a cross-section of the same with a wrapping paper in position. Fig. 4 is a cross-section of the same with the parts folded up so as to partially complete the former. Fig. 5 is a plan view of the same, the paper or wrapper being shown as gummed at one edge. Fig. 6 is a cross-section of the same after the materials for example, pruneshave been poured into the formerin sulficient a No. 108,997. (No speciinens-l quantity. Fig. 7 is a plan view of the same. Fig. 8 is a cross-section showing the former closed, so thatthe prunes are compressed together in one) direction and the edges of the paper are folded upon each other so as to form a'tubedike' package.

showing plungers compressing the contents as, for example, prunes from the ends within the partially-folded"wrapper. Fig. 11 is a plan view of the same. Fig. 12 is an 'end view of the package, the ends of the wrapper. having been folded over upon each other'and preferably sealed. complete package. v

Like parts are indicated by the same letter in all the figures. p

H H are plungers.

Fig. 9 is a plan view of the same- Flg. 10 Is alongitudmal section Fig. 13 is a plan view of the J indicates the folded ends of the wrapper, and Kthe'linepf overlap of the sides of the wrapper. As previously suggested, these parts could be greatly varied without departing from the spirit of my invention, and the exact order of the several steps is not essential.

The use and operation of my invention are as follows: Assuming that my process ,is to be carried out by a device such as that shown, I would furnish first the several'parts, properly folded together, of a former,'and they would as the first step be laid out so as to form a flat table. .Of course it might be partially folded up, but it is more convenient to have it flat, and on this table I lay downthe wrapper, in this case a piece of paper. It can he held in position in any desired manner, and

receive the prunes. or material. The Inaterials are'then inserted into this partly-prepared former directlyagainst the unfolded wrappen The processv of completing the folding of the'wrapper, in at least one sense, is then continued, preferably by folding over the portions of the former to complete the same. thus carrying down the two flaps or edges of the paper or wrapper. If, as indicated, they are gummed, then the wrapper will be formed into a tube-like body containing the material, sealed along the side or along the two edges of the side. of the package. This, however, leaves the material in a tubelike package open at one or both ends, preferably both ends. This material" must now be compressed within the package, and this is done by introducing the plungers, one or both of which may travel and which compress the material directly against the inner face of the wrapper. Obviously this does not endanger the wrapper, because it is backed up on either side by the inner surfaces of the former.

When the material has been sufiiciently compressed to form a package of the desired size and shape, the plungers may be withdrawn and the ends of the wrapper can be folded over and sealed in any. desired manner. This may take place within the former or after the package has been removed therefrom. This gives a complete finished package of compressed and wrapped material, the processes of forming the filling. the package being intertwined, as it were, so as to form one continuous and complete process, each step in each of the joined processes cooperating with the associated steps of the other processes to produce the new process.
