Preferably, the commodity is fed under compression in between the opposed lengths of wrapping material, maintained under compression while the wrapping material is side-sealed and is vacuum-packaged while also under compression.

Abstract: The present invention provides a selvage-forming device for use in a weaving apparatus, which selvage-forming device is of a relatively simple construction and yet effectively forms the selvage. The device comprises a rotatable plate upon which is mounted first and second supplies of thread. The thread from each supply of the same is preferably fed to a pre-guide member, through a guide means at the extremity of a tensioning arm, and through an aperture in the rotatable plate. The rotatable motion of the plate will cause the selvage threads to form the desired selvage.

Abstract: A liquid supply system and a nozzle construction for a jet weaving loom. The nozzle is supplied directly from a public water works at the normal pressure of said water works. The exact amount of water required to propel the weft yarn across the open harness shed of the loom is obtained by a solenoid valve series-connected to the water supply adjacent the nozzle and controlled by an electric pulsator which is adjustable to open the valve for the required time in accordance with the width of the weaving and the type of weft yarn. Synchronization of the operation of the nozzle with the harness motion is obtained by a switch controlling the pulsator and directly operated by a cam connected to a shaft of the main movement of the weaving loom.
