Definitions

• Figs. 11-12 are perspective views, showing portions of the operating wheel in two successive stages during the application of a closure tape.
• Carrier 11 comprises a movable carrier table 15 and a narrower fixed carrier table 14 located in opposition thereto in the middle of a long side.
• the perforated top thereof is at the same, ' or substantially at the same level as the top of the fixed table 14, as shown in Fig. 2a.
• Fig. 2b shows the location of pouch 50 in this position of tables 14,15: the pocket portion of the pouch lies on the movable table 15, with the flap side of the pouch facing up, and the flap proper resting on the fixed table 14.
• the fixed table 15 " is moved slightly downwardly relatively to the fixed table 14, as a result of which the pocket portion of the pouch is opened a little.
• the movable parts of the carrier 11 return to the starting positions illustrated in Fig. 2a. It is noted that all these operations on the pouch are carried out while supply wheel 10 rotates at a constant velocity, with the movable parts of the carriers 11 each completing a cycle during one single revolution of the wheel.
• a filling wheel 20 cooperating with the supply wheel at its circumference and rotating at the same peripheral velocity.
• the filling wheel is provided at its circumference with eighteen carriers 21.
• the bottom plate 58 is fixedly arranged at a level slightly above the upper surface of the carrier table 22 and is fixedly connected on two sides with upright sidewalls 60.
• the top plate 59 is at one end fixedly connected to an upright slide 61, and both are movable upwardly, with the top plate 59 moving parallel to, and away from, the bottom plate 58 to form a rectangular aperture defined by the two plates 58,59 and sidewalls 60.
• a weighedquantity of tobacco is shifted by an ejector 31 (Fig. 6) up to the bottom of the pouch.
• the situation is then as illustrated in Fig. 5.
• the tobacco is shifted further by the ejector and at the same time the carrier member 21 is returned from the filling nozzle to its starting position, and the now filled pouch moves off plates 58,59.
• the closing strip 25 is moved upwards, whereby the head 29 slides upwards through the slot in the carrier table 22 to above the surface of carrier table 22.
• the suction bar 23, now serving as a closure strip is swung away, and the pouch is pinched shut behind the tobacco filling therein between the suction bar 23 and closing strip 25.
• the folding strip 24 is moved upwardly, whereby the head 28 rises above the surface of the carrier table.
• the pouch flap is turned up to a position at right angles to the pocket portion between suction bar 23, closing strip 25 and folding strip 24, and the situation as illustrated in Fig. 6 is reached.
• the closing strip 25, the suction bar 23 and the folding strip 24 are returned to their starting positions.
• the tobacco shifted into the pouch comes from a product wheel 30 disposed coaxially with, and next to the filling wheel 20 , and has the same rotational velocity as the falling wheel.
• the roduct wheel contains eighteen identical compression chambers 32 (Fig. 1) spaced uniformly about its circumference and each cooperating with a carrier 21 of the filling wheel. Details of a compression chamber 32 are shown diagrammatically in Fig. 7.
• a measuring means which passes this data to the servomotor other control means which controls the degree of compression of the product in the compression chambers depending on the thickness of the pouch measured by the measuring means.
• a magnetic ring 63 Secured on top of frame 62 is a magnetic ring 63, which gives access to a filling space defined by the upright walls of frame 62 and the opened flap 37.
• the magnetic ring 63 serves as a dragger for picking up and carrying along a transport container which can be retained on the ring by magnetic force.
• the compression frame is first moved down relatively rapidly, whereafter in a slower movement the tobacco is more strongly compressed. If desired, the compression frame is thereafter moved upwards a few millimeters.
• the side rams 39 are moved towards each other into the compression chamber, whereby the tobacco is also compressed in a lateral direction. The result is that ultimately the tobacco has been pressed in three directions essentially perpendic to each other.
• the filling opening may be at the side rather than at the top of frame 62.
• the magnetic ring 63 is also disposed at the side of frame 62, and the containers on the various compression chambers have a horizontal and mutually parallel position. The tobacco should then be positively discharged from the container into the compression chamber. This construction may be attractive to limit the radial dimensions of the product wheel with the containers placed thereon.
• the containers are placed at the side of the compression chambers facing the wheel axis, and the tobacco falls from a full container into the compression chamber in a low position of the compression chamber on the product wheel.
• a closure tape unit 70 Arranged stationarily within operating wheel 40 is a closure tape unit 70, which contains a plurality of supply rolls 71 with webs of closure tape material and a sticking apparatus 72.
• the entire unit 70 is secured to pivoting arms 73, which are pivotable about a vertical shaft 74 mounted aside of the wheel.
• the entire closure tape unit 70 can be pivoted to the- outside through the open side of the operating wheel, which renders the unit readily accessible, for example, for placing fresh supply rolls in it.
