Definitions

• each housing channel 26 is (slightly) smaller than the axial length of the tubular casings 2 and therefore the tubular casings 2 protrude (slightly) both from above, and below the housing channels 26; according to other perfectly equivalent embodiments not illustrated, the axial length of each housing channel 24 is (much or slightly) greater than the axial length of the tubular casings 2 (therefore the tubular casings 2 are completely contained, without any protrusion, in the housing channels 24) or the axial length of each housing channel 24 is greatly smaller the axial length of the tubular casings 2 (in this latter case the tubular casings 2 widely extend both from above and below the housing channels 26) .
• Each group 30 comprises fourteen fingers 31 which are parallel and side-by-side one another and each finger 31 has three seats 32 each adapted to receive a corresponding tubular casing 2 (as better illustrated in Figures 8 and 9) ; It is important to note that the number of seats 32 of each finger 31 is equal to the number of lines of each group 11 of seats 12 of the manufacturing drum 9. As illustrated in Figures 10, 11 and 12, each second seat 32 is formed by a blind hole (obtained inside the corresponding finger 31) having a bottom wall on which a corresponding tubular casing 2 rests.
• the cam actuator device 33 is of the desmodromic type devoid of elastic elements, i.e. the translation movement of the fingers 31 is always imparted by cams which move the fingers 31 in both directions without using elastic thrust.
• the actuator device 33 can translate the fingers 31 of each group 30 into the feeding station SI (when the feeding drum 28 is standing still), in the insertion station S8 (when the feeding drum 28 is standing still) or in the path between the feeding station SI and the insertion station S8 (when the feeding drum 28 is moving) .
• the actuator device 33 comprises a motor (typically electric)
• the actuator device 33 is able to translate the fingers 31 of each group 30 even when the feeding drum 28 is standing still
• the actuator device 33 comprises cams which exploit the rotary movement of the feeding drum 28, then the actuator device 33 is able to translate the fingers 31 of each group 30 only when the feeding drum 28 is moving.
• the insertion station S8 is arranged in the closing position) so as to "isolate" the sections of the conveying channels 34 comprised in the insertion station S8 from the remaining sections of the conveying channels 34 and then the forty two tubular casings 2 in the insertion station S8 are transferred (with the methods described in the following) from the conveying channels 34 to the seats 32 of the fingers 31 of a group 30 that is standing still in the insertion station S8.
• the forty-two tubular casings present in the insertion station S8 have been transferred from the conveying channels 34 to the seats 32 of the fingers 31 of a group 30 that is standing still in the insertion station S8, the insertion station S8 is empty (i.e.
• tubular casings 2 completely devoid of tubular casings 2) ; at this point, the prongs of the accompanying device 37 are fed along the conveying channels 34 until reaching the gate 38 and therefore the gate 38 is opened (i.e. is arranged in the opening position) so as to allow the tubular casings 2 to enter the insertion station S8 again, sliding by gravity along the three conveying channels 34; the descent of the tubular casings 2 along the three conveying channels 34 and in the insertion station S8 is not free (i.e.
• the movement of the gate 95 is synchronized with the exact position of the sealing rings 7 inside the three conveying channels 91 in order to avoid errors in the handling of the gate 95.
• the movement of the gate 95 is controlled according to the exact position of the sealing rings 7 inside each conveying channel 91 detected by the video camera T in combination or alternatively to control the movement of the accompanying element 94 as a function of the exact position of the sealing rings 7 inside each conveying channel 91 detected by the video camera T.
