This invention relates to improvements cigar wrapping machines, and has reference particularly to mechanisms for applying a wrapper and winding it around a cigar-bunch. v

The present invention has reference particularly to a mechanism of the kind referred to comprising a cigar-heading block and has for its main object to provide a cigar-heading block having a wrapper supporting member and means for swinging said member so as to open said block, substantially with the view of permitting the wound cigar to be transferredfrom the wrapping mechanism in a simple manner and without being injured. Thus the heading block member does not interfere with the cigar on being transferred though said block is ordinarily mounted close to the bunch head to convey the rear or flag end of the wrapper to said head. 7

In the drawing Fig. 1 is a plan view of a device constructed in accordance with the invention; Fig. 2 is a longitudinal elevation of the device partly in section; and Fig. 3 is a cross section of the device taken on line 3-3 of Fig. 1.

Referring to the drawing two pairs of wrapping rolls l and 2 respectively are mounted in known manner on arms 3 pivoted to shafts 4 in the frame H3. A bell crank lever 5, one arm of which is pivoted to two iinks ii, is pivotally mounted on a rigid shaft 15 in the frame it. The other ends of the links 6 each pivoted to the arms The free end of the lever carries a roller 8 which is forced against a cam 9 by a tension spring I attached to the frame it at it and to the lever 5 at 5'5. The cam 9 is secured to a continuously rotating driving shaft H.

Adjacent one end of the wrapping rolls 1 and 2 is mounted a cigar-heading block it having a recess of substantially the same shape as the cigar head. The top end of one of the arms 3 constitutes a member i2 having such a shape as to form an upwards projecting wrapper supporting part of the heading block [3 when occupying a position indicated with dash and dot lines in Fig. 3 The block member is located at the wrapper supply side and immediately below the front edge of a tension plate 18 when the latter occupies its foremost position on delivering the rear wrapper end to the bunch head. .The operation of the tension plate 18 as well as its driving means are well known in the art and therefore a deing pincher shaped gripper 2i hinged to a pin 22 on said arm so as to depend vertically and impart a parallel movement to the cigar. The means for imparting rocking movements to the shaft 20 are well known in'the art, and therefore nodescription thereof isneeded herein.

In operating the mechanism a wrapper is supplied to a bunch M in the closed cluster consti tuted by the rolls I and 2 in well known manner for instance by a leaf carrier over the tension plate is. The rear or flag end of the wrapper which is usually pasted is dragged by the rotating bunch over the block member l2 and is completely wound on the bunch head. After finishing the rolling operation the cluster is opened by the cam 9 actuating the'lever 5 and the links 6 so as to swing the arms 3 with the rolls I and 2 apart to the position indicated with full lines in Fig. 3. Then the wrapped cigar rests in the heading block I3 and another rear supporting member (not shown). By swinging the left arm 3 (Fig. 3) aside, the block member 12 is likewise moved aside, and thus the heading block is opened to allow the cigar to be moved forwardly in a path of travel indicated by dash and dot lines in Fig. 2. This movement is obtained after having swung the arm 19 and the gripper 2i to seize the cigar by imparting to said arm a swinging movement in a reversed right hand direction according to Fig. 2.

I claim:-

1. In a cigar-wrapping machine the combination with a rolling mechanism of a cigar-heading block having a member for supporting an overlying wrapper when said Wrapper is supplied to the bunch, and means for opening the heading block by swinging said wrapper supporting member away from the other member of the block.

2. In a cigar machine having rolling mechanism and a tension plate, the combination of a cigar-heading block having a member for supporting an overlying wrapper and being arranged adjacent said tension plate, and means for opening said heading block by swinging said wrapper supporting member, in a ih'rection forwards said tension plate.

3. In a cigar-wrapping machine the combina' tion with a rolling mechanism of a cigar-heading block having a member for supporting an overlying wrapper when said wrapper is supplied to the bunch, a plurality of wrapping rolls, and

means for opening said rolling mechanism by swinging the rolls and the wrapper supporting member aside simultaneously.

6. In a cigar-wrapping machine the combination with a rolling mechanism of a cigar-heading block having a member for supporting an overlying wrapper when said wrapper is supplied to the bunch, a plurality of wrapping rolls, and transversally movable members supporting said wrapper supporting member together with part of said 10 wrapping rolls.
