- ,y 17 Claims.

1 I'his invention relates to shaping of filled bags and at the same time toyr compacting or settling flour or other powdered or granular material in bags, particularly paper bags.

Heretoi'ore, the common way of doing this has been to run the lledbags over a jogging table y having a conveyor means for feeding thebags forward while. they are shaken up and down. Due to the pounding from beneath, the bag often buckles and develops wrinkles in its'sides which i is sloppy in appearance and deiicient .in .the'display value it should have.

The bags used may |be of any well knowntype such as Satchel bottom or. automatic which are so constructed that they have a rectangular bottom which assumes a naturally rectangular.

form when filled and shaped. The bags are iirst iilled in a well known manner from a filling tube so that the greater part of the bag above the bottom is nearly round las shown in dotted lines at the left oi Figs. 2 and 31.y The bags, however, are fed to the machine in such a way as to insure the sides of the rectangular bottom running par-y allel to the line of travel through the machine.

The bag can ,then be shaped to a nearly rectangular form in which the sides are ilat and parallel to the sides oi the rectangularibottom. y An object of' this invention is to-provide a process of and means for shaping of `iilled bags and at the same time compacting our and like material in bags which will insure elimination, to a 1 large extent, of some or all of thefoijegLoing'.

defects.

To accomplish this, I suspend the bag by the top and apply a vibrating pressure to the sides to squeeze out the air and compact the ilour.

The apparatus for doing this settling is fully described in the following specication and is shown in the accompanying drawings in which -plates closed;
