2 Qlaims. (am-87 -One object of'my invention is to provide novel means for cutting associated and longitudinally folded webs each cycle of the cutting means into an odd number of signatures and means for delivering the signatures to a corresponding odd number of different points, as,. for instance, traveling endless tape carriers.
Another object is to provide means for mate rially reducing the speed of travel of the signatures so that each signature will not interfere with the leading edge of its next succeeding signa-- ture, and for improving the signature handling conditions at the several points of delivery.
Another object is to provide a traveling side guide for the signatures as they are conveyed by their respective endless tape carrier deliveries ;with the folded edges of the signatures disposed a parallel to the direction of travel of the carriers; .said traveling side guides being driven at the speed of the endless tape carriers and serving to overcome the tendency of the signatures to slide sideways oil the tape carriers.
A practical embodiment of my invention is iilustrated in the accompanying drawings in connection with means for cutting three signatures from the associated and folded webs each cycle 1 of the cutting means and delivering the signavJ tures under reduced speed to their respective first, second and third endless delivery carriers.
Fig. 1 represents a side view in diagram of the web' associating, folding, cutting and signature delivery mechanisms.
folding webs into three signatures each cycle of the cutting means and the means for delivering the signatures to three different points are shown as comprising the following elements. The pair of coacting rotary cutters are denoted by 8, 8. the first and second transfer cylinders by I 0, II, the first, second and third delivery cylinders by I2, I3, I4 and their respective endless tape carriers byI5,I6andI1.
The associated and folded webs, the rotary cutters 8, 9 and the transfer cylinders III, II are all driven at the same surface speed and the Fig. 2 represents an end view in diagram of the I web associating and foldingmechanism. Fig. 3 represents a detail plan view showin two first signature deliveries in diagram.
Figs. 4 and 4a represent a detail vertical section of the cutting and delivery mechanism on an' enlarged scale taken inside the near side frame.
Figs. 5 and 5a represent a detail vertical central Figs. 6 and 6a represent a detail vertical section showing the geared connection for driving the cutting and delivery mechanism and including a portion of the means for driving the traveling endless tape carriers and their traveling side guides.
While I have shown a mechanism which is capable of simultaneously handling two sets of narrow webs the mechanism and its operation will be described in connection with one only of these two sets of webs. I
The mechanism for associating and folding the narrow webs is shown as comprising a pair of three delivery cylinders I2, I3, I4 are all driven at a slower surface speed, in the present instance about six-tenths that of the associated and folded webs, the rotary cutters and the transfer cylinders.
The sequence of operation is such that the first signature cut from the associated and folded webs during one cycle of the rotary cutters is delivered to the first endless tape carrier IS; the second signature cut during the same cycle of the rotary cutters is delivered to the second endless tape carrier I6, and the third signature cut during the same cycle of the rotary cutters is delivered to the third endless tape carrier'I'I, the cutting of the three signatures completing the cycle of the rotary cutters.
The driving connection between the rotary cutters, the transfer cylinders and the delivery cylinders is such that two successive groups of three signatures are delivered during one cycle of the delivery cylinders and two cycles of the gear 23 on the shaft of the second transfer cylinder II; the coacting gears 24, 25 on the shafts of the first transfer cylinder I0 and second delivery cylinder I5; and the coacting gears 26, 21 on the shafts of the second transfer cylinder II and third delivery cylinder I4.
It will be understood that the three delivery cylinders are driven at a considerably lesser surface speed than that of the rotary cutters. This is shown as being accomplished as follows. The three delivery cylinders have a materially greater diameter than that of the rotary cutters and the ratio between the gears is as follows. ratio between the coacting gears I8, I9 is one to one; between the gears 29, 2| is one to two; between the gears I9 and 22 is one to two; between the gears 22 and 23 is two to one; between the gears 24 and 25 is one to one; and'between the gears 26 and 21 is one to two.
The devices on the rotary cutters and various cylinders which operate to cut and deliver the signatures will now be described. 7
The rotary cutter 8 is shown as provided with a knife box 28 and two knives 29, It equally spaced apart around the periphery of the cutter, and also one set of cam operated impaling pins II located at the knife block 28 to engage the first signature. A fixed cam 32 is located in position to withdraw these pins 3i to permit the first signature to be transferred from the rotary cutter 8 to the delivery cylinder I2.
The rotary cutter 9 is shown as provided with a knife 33 and two knife boxes 34, 35 equally spaced apart around the periphery of the cutter, and two sets of cam op'erated impaling pins 36. 81 located at the knife boxes 34, 35. A fixed cam 88 is located in position to withdraw these impaling pins 35, 31 to permit the second and third signatures to be transferred from the rotary cutter 9 to the first transfer cylinder I0.
The first transfer cylinder I is shown as twice the diameter of the rotary cutters 8, 9 and it is provided with four sets of cam operated impaling pins 39, 49 and H, 42 spaced apart around.
the peripher of the transfer cylinder as follows. The impaling pins 40 are spaced one-sixth of the periphery-from the impaling pins 39; the impaling pins H are spaced two-sixths of the periphery from the impaling pins 40; the impaling pins 42 are spaced one-sixth of the periphery from the impaling pins 4|; and the impaling pins 99 are spaced two-sixths of the periphery from the impaling pins 42. A fixed cam 43 is located at one end of the first transfer cylinder in position to withdraw impaling pins 42 to transfer the second signature to the second, delivery cylinder I3 during the first cycle of the rotary cutters and the impaling pins 49 during the second cycle of the rotary cutters. A second fixed cam 44 is located at the other end of the first transfer cylinder in position to withdraw impaling pins 4| to transfer the third signature from the first transfer cylinder III to the second transfer cylinder II during the first cycle of the rotary cutters 8, 9 and the impaling pins 39 during the second cycle of the rotary cutters.
The second transfer cylinder II is shown as one-half the size of the first transfer cylinder l0 and as provided with one set of cam operated 4 impaling pins 45 on its periphery. A fixed cam 45 is located in position to withdraw the impaling pins 45 to permit the transfer of the third signature from the second transfer cylinder to the third delivery cylinder I4.
The first delivery cylinder I2 is shown as provided with two grippers 41, 48 equally spaced apart around its periphery. A fixed cam 49 is located in position to operate the grippers 41 to take the first signature in the first cycle of the rotary cutters from the rotary cutter 8 and the grippers 48 to take the first signature in the a second cycle of the rotary cutters and to deposit The the succeeding first signatures onto the endless tape carrier II.
The second delivery cylinder I8 is shown as similarly provided with two grippers 50, 5| equally spaced apart around its periphery. A fixed cam 52 is located in position to operate the grippers 5|! to take the second signature from the first transfer cylinder during the first cycle of the rotary cutters 8, 9 and to operate the grippers ii to take thesecond signature from the first transfer cylinder I0 during the second cycle of the said rotary cutters.
The third delivery cylinder I4 is shown as similarly provided with two grippers 53, 54 equally spaced apart around its periphery. A fixed cam 55 is provided for operating the grippers 53 during the first cycle of the rotary cutters 8, 9 to take the third signature from the second transfer cylinder II and the grippers 54 for taking the third signature from the second transfer cylinder II during the second cycle of the rotary cutters-8, 9 and to deposit the signatures on the third endless delivery carrier I1.
Three stops 55, 51, 58 are provided for the signatures as they are deposited onto their respective endless tape carriers I5, I6, I1 by the signature delivery cylinders I2, I3, I4.
Stationary vertically disposed guide plates 59, 60, 5| are provided along the endless tape carriers I5, I5, I1 at the signature delivery cylinders I2, I3, I4 on-the folded edge side of the signatures as they are deposited onto their respective endless tape carriers.
Because of the tendency of the signatures to move sideways off the endless tape carriers where the folded edges of the signatures are parallel with the travel of the endless tape carriers and the signatures arenarrow, traveling endless belts 62, 53, 84 are provided along the sides of the endless tape carriers opposite the stationary guide plates 59, 80, 6|.
Means are provided for driving these guide belts and endless tape carriers at the same slow speed, said means comprising the following elements. Crank pins 65, 65, 61 on the shafts of the signature delivery cylinders I2, I3, I4 are connected by links 58, 59, 10 to the rock arms H, 12, 13 of one-way clutches 14, 15, 16 on the cross shafts 11, 18, 19 on which the pulleys 80, BI, 82 of the endless tape carriers are mounted. These cross shafts 11, 18, 19 drive through pairs of connecting gears 83, 84, 85, 86, 81, 88, the vertical shafts 89, 90, 9I which carry the belt driving pulleys 92, 93, 94.
The means for associating and folding the traveling webs shown and described but not claimed herein form the subject matter of my copending application filed February '1, 1945, Serial No. 576,564 of which this application is a division.
It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiment herein shown and described, but what I claim is:
1. Means for delivering associated and folded signatures, including an endless tape carrier, a delivery cylinder for depositing the folded signatures thereon with their folded line parallel to the travel of the tapes, a stationary vertically disposed guide plate located along one side of the tape carrier at the delivery cylinder on the folded edge side of the signatures, an endless belt extending along the opposite side of the tape carrier parallel thereto and acting as a traveling side guide for the open edge side of the said folded signatures for overcoming the tendency of the signatures to slide sideways off their tape carrier, and means for driving both the belt and tape carrier at the same speed.
2. Means for delivering associated and folded signatures, including an endless tape carrier, a delivery cylinder for depositing the folded signatures thereon with their folded line parallel to the travel of the tapes, a stationary vertically disposed guide plate located along one side of the tape carrier at the delivery cylinder on the folded edge side of the signatures, an endless belt extending along the opposite side of the tape carrier parallel thereto and acting as a traveling side guide for the open edge side of the said folded signatures for overcoming the tendency of the signatures to slide sideways off their tape carrier, and means'operated by the delivery cylinder for driving both the belt and tape carrier at the same speed.
