Dresden, Germany, assignors, by mesne assignv ments, to J. C. Muller N. V., Rotterdam, Netherlands Application April 13, 1938, Serial No. 201,772 In Germany May 15, 1937 10 Claims. ,(Cl. 131-30) This invention relates to Cigar making machines, and more particularly to a means in combination with a wrapping machine for firmly holding the end of the Wrapper rst applied to the filler in a manner so that the rst end of the wrapper will readily adapt itself .to the configuration of the filler.

At the present time in the making of cigars by machines the wrapper is carried to a position for engagement with the filler by a suction carrier, the construction of which is well known, and the wrapper is -then removed from the carrier and the free end started on an end of the filler. The removal of the wrapper from the carrier is accomplished by means of a resilient finger which not only removes the initial or starting end of the wrapper from the carrier, but also applies this end of fthe 'wrapper onto the end of the filler. Due to the varying configuration of the cigar ends difficulty is experienced at the present time in snugly applying the starting end of the wrapper on the filler, `and it is, therefore, :an object of this invention to provide a Wrapper applying means which can be used with varying types of cigar ends and which irrespective of the configuration of the end of the cigar filler will snugly and firmly apply the starting end of the wrapper on the filler.

It is `also an object of this invention to provide a Wrapper applying means which is so constructed that it can be accurately timed in its operation with the ll-er mechanism so that the cigar production can proceed at a relatively rapid rate.

With the foregoing and -other objects in View, the invention will be more fully `described hereinafter, land will be more particularly pointed out in lthe claims appended hereto.

Figure 4 is a detail end elevation of the structure shown in Fig. 3.

Figure 6 is fa detail view'of the parts operating finger 26 of Figure 3.

Figure 7 is a like view but with the feeding finger pressed down further and folding the end of the wrapper thereabout.

understood that additional rollers 40 are used to engage about the filler W for the purpose of tightly wrapping Ithe Wrapper D thereabout.

The' rollers I are secured #to shafts I awhich are journalled in bearings 2 and 3 carried'by the frame structure 2I. Spur gears 4 are X-ed to the shafts I a adjacent the bearing 3 and mesh with a relatively large spur gear 5 secured to a countershaft 6. A smaller spur gear 1 is fixed to :the shaft 5 and meshes With a driving gea-r 8 which is -fixed to a drive shaft 9 connected to a suitable source of power. y

The frame 2l is provided with an outstanding arm 2i), and a lever I5 is pivotally mounted on this arm 20 by means of a pin I9 which engages the lever I5 between the ends thereof. The upper end of the arm I5 is provided with a recess I6, Figure 6, in which a bar I2 engages, and this -bar I2 is adjustably held in the recess I6 by means of a bolt I'I extending through an elongated slot I8 in the arm I5. The slot I8 is disposed substantially parallel with the `axes of the shafts I a so .that the adjustment of the bar I2 may be made longitudinally of the shafts Iaand the rollers I.

A socket generally designated as I0 is mounted on or secured to an arm II which is provided with a slot I4 adjacent the lower end thereof, and the arm II is adjustably secured to Ithe bar I2 by means of a bolt I3. In this manner` the arm II may be `adjusted vertically so as to properly position the socket I0 with respect to the end Sp of the ller W. The sock-et I0 is preferably open on its upper side, as at 29 so that the end E of the wrapper D may enter the socket,

and at one side of the opening 29 an upstandingl The wrapper D is positioned over the ller rolls by means of a movable carrier 25 the operating features of which are well known and not believed necessary to illustrate. The carrier 25 is provided in its under surface with a downwardly opening slot 21 in which the finger 26 is adapted to engage so as to be positioned on the upper side of the wrapper D.

The socket IU is rocked toward and away from the filler W by means of a disc 24 which is fixed to the drive shaft 9 and which is provided with a cam flange 23. 'Ihe lower end of the lever I5 is provided with a roller 22 which engages the cam 23, and a spring 2|a yieldingly holds the roller 22 in contact with the cam 23, one end of the spring 2|a being secured to a part of the frame 2| and the other end of the spring 2|a being secured to the lower end of the lever l5.

The spring finger 26 may be mounted on a suitable part of the frame 2|, engaging in a slot 3a provided between the bearings 3, and this finger 26 is normally biased to` an uppermost position as shown in full lines in Fig. 3. With reference to Figure 9, the tucking needle 26 is swung down against the end of the wrapper E by a rod 4| pivoted on the end of an arm 42 which has its lower end pivoted in a bracket 43 and which carries a crank roller 44. A spring 45 on the bracket 43 engages the arm 42 and holds the roller 44 yieldingly against the periphery of a disc 46 driven through gears 41 from the shaft 9. The disc 46 has a cam or raised portion 48 on its periphery which engages the roller 44 and swings the arm 42 and the rod 4| toward the needle 26, as shown in dotted lines in Figure 9. Spaced stops 49 on the needle engage the eye of the rod 4| and move the needle back and forth with the rod 4|. The needle passes through the top of the frame 3 and the forward stop 49 tapers to engage the frame and tilt the needle 26 downwardly, as shown in Figure 9 in dotted lines.

In the use and operation of this device, the carrier 25 is swung to a position where an end of the wrapper D overlies the socket when the socket is in operative position, or in the position shown in full lines in Fig. 3. The nger 26 is so positioned that the swinging of the carrier 25 to a discharging position will also cause the end of the finger 26 to enter the slot 21 above the wrapper D. The finger 26 is then swung downwardly and as the nger 26 engages the wrapper D inwardly of the adjacent end thereof the downward swinging of the finger 26 will bend the free end of the wrapper D as shown in Figs. 6 and 1, the end of the wrapper D sliding down along the surface 3|] of the flange 28. The filler W at this time is rotating in the direction of the arrows shown in Figs. 6, 'I and 8, and as the bent end of the wrapper D passes downwardly through the opening 29 and contacts with the filler in the socket |6 both the wrapper D and the finger 26 are drawn into the socket |l as shown more clearly in Fig, 8 with the bent portion of the wrapper folded about the finger 26. The finger 26 makes a complete revolution within the socket IU and is bent to the configuration of the socket H) by pressure of the socket l0 against the end Sp of the filler W. After one revolution of the filler and finger 26 in the socket lll the finger 26 is dis-` placed longitudinally toward the left of Fig. 3 by its operating mechanism shown in Fig. 9.

When the wrapper D is completely disposed about the filler W the cam 23 will swing the socket I0 to a released position, shown in dotted lines in Fig. 3. The completed cigar may then be removed from the rollers I and a new filler inserted and the operation repeated. By means of the adjustable mounting for the socket Il), the axis of this socket may be finely adjusted with respect to the axis of the filler W, and the longitudinal adjustment of the bar |2 will permit the positioning of the socket 0 in a manner to firmly press against the adjacent end of the filler W. The detachability of the socket l0 will permit the use of any desired socket configuration, and the use of a resilient finger 26 will permit the use of any desired socket without changing the other parts of the device, as the finger 26 will readily adapt itself to any socket configuration. The longitudinal adjustment of the socket I0 with respect to the rollers will also permit the use of this structure with any length of filler, so that a wrapping machine equipped with this invention may be used with cigars of different configurations and sizes both as to diameter and length.

. It will be apparent from the foregoing that the starting end of the wrapper will be rmly and snugly held against the end of the filler, irrespective of the configuration of the adjacent end of the filler, as the pressure of the socket l0 against the end of the filler W is sufficient to effect a bending of the finger 26 coincident with the shape of the socket I0.
