Abstract:
A machine (10) and process function to fill cavities (16) with metered amounts of particulate material is disclosed. An applicator wheel 18 includes a series of equally spaced apart peripheral pockets (24) each having a perforated bottom wall (32), and a vacuum manifold (34) inside the wheel includes a vacuum chamber 38 for supplying vacuum to the perforated bottom walls of the pockets as the wheel rotates. Particulate material (20) from a filling chamber (26) of such material outside the wheel is withdrawn into the pockets by the vacuum chamber. A downstream vacuum relief (48) on the vacuum manifold functions to discharge particulate material from the pockets into the cavities at a predetermined discharge location on the wheel. Adjustment structure (52, 54) is connected to rotatably adjust the position of the vacuum manifold within the applicator wheel to thereby advance or retard the discharge location depending upon the speed of the machine.
Abstract:
A bead feeder for serially delivering beads 12 to a downstream location comprises a bead supply wheel 14 which rotates about a vertical axis 20. The bead supply wheel includes a bead supply bowl 22 and a plurality of radially arranged channels 24 below the bowl connected to rotate with the bowl. Discharge openings 26 in the bowl are in alignment with the radially arranged channels to delivery beads to those channels, and a bead receiving pocket 28 is positioned at the outer end of each channel. A transfer wheel 16 picks up beads from the bead receiving pockets and transfers those beads to a delivery wheel 18 by vacuum transfer and release. The delivery wheel serially delivers the beads to the downstream location.

Abstract:
An apparatus and methods for producing at extremely high production speeds small pouches (100) filled with tobacco or other granular, powdered or solid content. An endless web substrate (12), with or without flavor film (14) thereon, is formed into a tubular shape (29) with a longitudinal seam (106). The tube (29) is cut to individual lengths (10V), and a procession of tubes is crimp-closed at one end (102), filled and crimp-closed at the other end (104) to complete pouch production. During production, the seams formed at the crimped ends (102, 104) of the pouch are parallel to one another and the longitudinal seam (106) of the pouch (100) is midway between the sides of the pouch (100) and orthogonal to the seams formed at the crimped ends (102, 104) of the pouch (100).
Abstract:
An apparatus (10) for producing cigarette filter tubes (50) comprises a rotating delivery drum (22) and a supply of filter segments (54) from a hopper (18) and a supply (12) of paper wrapper to the delivery drum. The paper is partially wrapped around the filter segment. Thereafter, the paper wrapper and the filter segment are transferred together from the delivery drum to a rotating wrapping drum (28). Folding arms on the wrapping drum subsequently fold down flaps of the paper wrapper to complete the formation of a filter tube. Wrapping assist members may be inserted into the paper wrapper as the flaps are folded down to ensure that the tube is sufficiently round in shape. Additionally, the wrapping assist members and folding arms may be heated in order to promote faster curing of glue surfaces on the paper wrapper. A method for producing cigarette filter tubes is also described.
Abstract:
A method and apparatus (8) for forming filter tubes (36) is disclosed. A filter element (10) is delivered to a flute (13) on a feed drum (12) having vacuum for securing the filter element thereto. First and second tube forming rollers (30,32) axially engage opposite ends of the filter element. A tipping drum (20) accepts and cuts a continuous paper web with a glue pattern thereon into paper pieces (22), and a cut paper piece is delivered to the filter element. The paper piece is then rolled around the filter element and the tube forming rollers to form a cylindrical shape. The tube forming rollers are axially disengaged to thereby produce a filter tube with hollow ends and a control positioned filter element.
Abstract:
A machine for producing an endless filter rod comprises a multi-section garniture and a multiple garniture belt drive system that includes several garniture belts having linear aligned portions for delivering filter paper with filter components thereon through the sections of the garniture. Multiple garniture belts eliminate the need for a long belt and the disadvantages associated with a long belt such as excessive stretching and side movements or wander of the belt.
Abstract:
Se describen un aparato y métodos para producir bolsas pequeñas (100) a velocidades de producción extremadamente altas llenas de tabaco u otro contenido granulado, en polvo o sólido. Un substrato de banda sinfín (12), con o sin una película de sabor (14) en el mismo, se hace con una forma tubular (29) con una costura longitudinal (106). El tubo (29) se corta en longitudes individuales (10V), y una procesión de tubos se cierra por fruncido en un extremo (102), se llena y se cierra por fruncido en el otro extremo (104) para completar la producción de bolsas. Durante la producción, las costuras formadas en los extremos fruncidos (102, 104) de la bolsa están paralelas entre sí y la costura longitudinal (106) de la bolsa (100) está a la mitad entre los lados de la bolsa (100) y ortogonal a las costuras formadas en los extremos fruncidos (102, 104) de la bolsa (100).
