With known Poat franking machines, precautions are taken ue to print a postal mark on tape and on envelopes. Most of the time, such machines are mainly used Used for printing on envelopes and the leading end of the tape is out of the path of travel of the envelope through the printing station held. If a printed tape strip or mark is desired, the movement of the Band from its normal rest position in time Relationship to the cyclical rotation of the franking drum which the postal codes carried so that the printed identifier is properly located on the tape when the tape is cut off to form the strip. Inevitable control of the belt to this ratio It is still necessary to maintain between the movement of the belt and the rotation of the printing drum required to ensure that the postage stamp is complete and legible every time the Machine to ensure.

In many known devices, the leading edge of the tape is usually in readiness Graduation for movement of the tape through the printing drum when the identification stamp engages with the tape. The tape is then moved to a cutter and then through the co-operation two training rolls withdrawn, which are in are in constant engagement with each other to hold the tape between them. When the Identification stamps with the tape can suddenly move or move to a greater extent than normal the belt movement can be temporarily limited by the clumps. In each of these cases, the printing process runs to an incorrect or illegible postmark.

700318715.10.70

In other cases, a large number of toothed or non-toothed sectors work with a counter-holding roller together to engage the tape and cause movement of the tape. if a sector of any one of these types initially engages the tape to advance the tape or withdraw, some amount of idle movement may occur, so that one does not results in a satisfactory imprint. These results are from the point of view of loss of postage or postage and / or waste of tape expensive.

If tape strips, the mail imprints changing If names or values are to be created, the value selection must be made in known devices can be changed with each operation. Should the operator fail to make the value selection before each To change the work process, a printed strip will appear or a printed stamp with a higher or lower value than desired, delivered, resulting in a significant loss of postage or postage value over an extended period of time.

It should be noted that when entering or setting the value selection keyboard 13 for a Postage franking a number of type characters bearing print wheels in the printing drum 15 in a known manner from a zero representation up to a value representation is set in accordance with the input on the keyboard 13. If an incorrect postage value has been entered on the keyboard 13, or if so desired is to change the keyboard setting, the keyboard 13 erasing process is initiated, around the type wheels of the printing drum 15 in the zero position postpone. For this purpose, the driving part 69 of a circuit clutch 70 is on the Main drive shaft 25 (Pig. 5) attached. The driven part 71 of the circuit clutch or cyclic Coupling 70 is attached to one end of a sleeve 72 which is rotatable on shaft 25 and to the other End carries a switch control cam 73, the operation of which will be described below. On the sleeve 72 is also attached between the driven part 71 and the cam 73, a deletion cam -74, the via a cam follower arm 75 and its sleeve 76 is effective to an angle lever or an angle crank 77 to move back and forth, whereby a keyboard 13 erasing operation is caused. The cyclic clutch 70 is of conventional design and is usually in the disengaged state, by means of a clutch control lever 78 which is schwingabr about a pivot support rod 79 to to cause the clutch to engage when a solenoid 80 is energized.

For printing a postal mark on a Umschiag or another post office will be the engine and the cyclic clutch 29 which have a cycle

700318715.10.70

of a franking process controls, energizes or engages brought by a release part actuated by the envelope when the envelope is passed between the printing drum 15 and the pressure roller 40. Such a trip device does not form part of the invention and is therefore not shown.

In addition to printing a mailing identifier on envelopes, the postage meter continues to be provided with means by which a post mark or a post mark on a through the machine running rubberized tape can be pressed. After printing, the tape is cut off, around a printed strip for subsequent dispensing in a moist or non-moist state for attachment to any type of mail item. After cutting the tape the tape is used to create the printed strip withdrawn to an initial boo position in which it is outside the path of movement of an envelope is held. At this time, an operation to erase the keyboard 13 may or may not be performed depending on how it is determined by the preselected setting of a control button.

As mentioned above, the invention is described here using a postage meter, but it is to understand that the invention can be applied to any type of printing device.

The tape T, which is fed in hollen, as shown generally at 85, is disposed in a removable cartridge 86, the tape T according to Pig. 2 and A is pulled counterclockwise from the roll. The ribbon cartridge 86 is generally helical in shape and is preferably shaped or otherwise made of thermo-aluminum

In this position of the bail 109 a ^a is tange 110 similar at their ends to downwardly extending lugs 111 of sliders 112 and 113 of the bracket 109 are arranged under similar shoulders 114 formed in the side walls SB and 99 of the cartridge 86. Each of the sliding parts 112 and 113 is close to the respective side wall 98 and 99, respectively of the cartridge 86 and is adjustably supported thereon by engagement of similar elongated slots 115 with bolts 116 attached to the side walls around the bracket shown in Figure 2. The sliding portion 113 of the bracket 109 is provided with an end portion 117 elongated upwardly at an angle provided for manual control of the adjustment of the bracket 109. A laterally formed projection 118 on the elongated end portion 117 protrudes outward and is used for engagement t the top of the base plate 20 to limit the downward movement of the bracket 109 around the bolt 116.

When the door 88 in the lid 23 is open and. the bracket 109 is in the in Pig. 2 is the position shown, a roll of tape 85 is in the Cartridge 86 is inserted by entering the ends of the tape reel spindle 122 into similar channels 123, the in the side walls 98 and 99 are formed, thereby providing an adjustment for counterclockwise rotation of the roll of tape Show establishment in a suitable recess in each of the channels 123 is created. After ordering the tape feed roll 85 in the cartridge 86 causes the tape roll 85 to rotate slightly the operator counterclockwise that the front end of the tape T is in the position for

threaded through a tape feed process. For this The purpose is an adjustable arcuate guide plate 124 at its lower end on a shaft 125 (Fig. 2 and 4) attached, which is mounted at its ends in the side walls 98 and 99. about the pivoting movement Controlling the guide plate 124 is an arm 126 at an extended end of the shaft 125 attaches and angularly mounts a laterally projecting bolt 127 at its free end for engagement with the formed cam surfaces 128 and 129 of a cam part 130 which is formed on the slide part 113 (Fig. 2). In the tape input position of the bracket 109 and the sliding part 113, as shown in FIG is, the cam surface 128 is in engagement with the bolt 127 to the guide plate 124 in the tape threading position shown by broken lines, with the curvature the guide plate 124 corresponds essentially to the curvature of the circumferential surface of a full roll of tape 85.

At this point the tape roll 85 is rotated counterclockwise by hand as shown in FIG . When leaving the throat 131, the front end of the belt T comes between two parallel guide plates! 135, which are secured between the parallel .Armen 137 and 138 of a bracket 139 which Ile at the W _e 105 supported swingably i ^, t During the threading passes the front end of the tape T between an auxiliary roller or pressure roller 140 and a tape feed roller 141, each of which has a coating of training material, preferably rubber. A drive gear 142 is at one end of the hollow 140

700318715.10.70

attached and the pulley 140 and the gear 142 are rotatably supported on a shaft 143, which find their in the arms 137 and 138 of the bracket is attached. The gear 142 meshes continuously with a driving gear 144, which together with a drive gear 145 at one end of the tape feed rc He 141 is attached, which i <? t supported on a * elle rotatably, which in turn at their bands is supported in the "slopes 47 and 48 of the yoke 46. Usually the pressure roller 140 is in the in 4 held to the tape T in friction contact with the tape feed roller 141 to hold. However, the bracket 139 according to FIGS. 2 and 4 can swing in the clockwise direction to prevent the passage of the leading end of the tape T between the pressure roller 140 and the tape feed roller 141 during the threading process to enable.

For this purpose, the upper edge 147 of the extended band part 148 of the slide part 95 (Figs. 2 and 4) is beveled so that a squat surface is created which is in engagement with a boll 149 which is at an extended end of the shaft 143 (Fig. 3) is supported. When access door 88 is opened to allow the insertion of a new tape roll, the slider 95 is moved from the shown in Fig. 4 position to the right in Fig. 2 reproduced position, whereby the bracket is pivoted in the counterclockwise direction 139 "ird _s in order to create enough tree between the pressure roller 140 and the tape feed roller 141 for the passage of the leading end of the tape T during the threading process.

After inserting a reel of tape 85 will be the extension 117 of the sliding part 113 detected to

The key 194 is at one end on one Taatenachaft 196 attached, the other endi at attached to the end of a We2le197 13t, which in a Bushing 19S is mounted, which on the subframe plate 163 is attached. The shaft 197 carries on hers opposite end has a cam arm 201 which is pinned to it and which engages with a roller

stands by an L-shaped switch operating arm 202 is carried, which takes effect when the button 194 is pivoted, usually open microswitches 203 and 204 attached to the subframe portion 163 side by side.

The button 194 is usually biased upwardly by a spring 205 into engagement with a limit pin 206, which is carried on the subframe part 163. The spring 205 is at one end thereof Bolt 206, and on its other, find a suitable pin or bolt on the key shaft 196 supported. When the key 194 is pivoted downward and it immediately returns to the position shown in FIG reproduced normal position is a single machine cycle for a tape feed and printing initiated. The closing of the switch 203 by pressing the button 194 leads for -excitation of the motor to make continuous rotation the main drive shaft 25 cause while by closing the switch 204, a solenoid 207 is temporarily energized, which is located on the stand 21 is attached and -engaging or engaging the semi-circuit clutch 195 causes.

It should be remembered that when the motor is energized and the main drive shaft 25 the gear train 41, 42 (Fig. 3 and 5) via the cardan connection 44 is effective to the ^ eIIe 45 and to impart continuous rotation to the pressure roller 40. At the same time, the belt control clutch is engaged 195 effective at one and a half revolutions of it, around a single rotary circuit of a camshaft 208 (Figs. 3, 4 and 9). As shaft 208 rotates, a number of attached to it serve Cam to keep the motor energized to advance the tape T to the printing station for a

cause individual working cycle of the Post.iertdruckeinrichtung, continue the advance movement of the tape T into the cutting position, actuate the cutting knife and then pull the tape ^{T back} into its starting position.

According to FIGS. 3, 5, 7 and 8, the tape feed clutch 195 is of conventional design and it ■ includes drive half 212 attached to main drive shaft 25, a clutch engagement disc 213 and a driven half 214 attached to the finding of a sleeve 215 which is rotatable on the main drive shaft 25. At its other end, the sleeve 215 carries a 24-tooth sleeve Gear 216 that meshes with an idler-like pitch diameter that is attached to a Stub shaft 218 is rotatably supported, which is attached to the frame part 21. The idler gear 217 meshes in turn with a gear 219 having 36 teeth, which has a hub 220, the a stub shaft 221 is attached, which is mounted in a bushing 222 in the frame part 21. It is thus it can be seen that for each rotation of the belt coupling 195 of 180 ° the gear wheel 219 one rotation of 120 ° is granted. The gear 219 and its hub 220 are by means of a cardan drive connection 223 is drivingly connected to the camshaft 208.

In order to engage the belt coupling 195 for according to Pig. To cause a counterclockwise rotation, the armature of the solenoid 207 has a bolt-slot engagement with an angled or recessed downward arm 227 of a bracket 228, which _{is pivotable on a W e} ii _e 229 which is attached to the frame part 21 is attached (Pig. 3, 5 and 7). The bracket is usually counter-clockwise in the £ Pig inoperative position. 7) by means of a spring 230

pressed, at its one end in a suitable opening in the lower end of the standing down Arm 227 of the bracket 228 and is supported at its other end on a bolt 231 on the frame part 21. The arm 227, which extends downwards, carries a driver pawl 232 between its ends, which is attached to it at 233 is pivotably supported. Usually a spring biases 234-. the kind your lower find in a suitable one Opening in the lower end of arm 227 is attached and supported at its upper end on a laterally projecting shoulder of the pawl 232, the pawl 232 counterclockwise in the Pig. 7 position shown resiliently forward. In In this position there is a laterally arranged shoulder 235 on the pawl 232 in locking engagement with a groove 236 formed in the lower end portion of an elongated downward arm 237 of a clutch engagement bracket 238 is formed, which is pivotable on a part 229. The clutch engagement bracket 238 is resiliently held in the clutch disengagement position by means of a spring 241, which is fastened at one end in the web of the bracket 238 and at the other end to a bolt 242 which is carried by the frame part 21.

The free end portion of the locking pawl 232 is close to the driven portion 214 of the coupling 195 and in the plane of rotation of two diametrically opposed bolts 239 and 240 which protrude outward therefrom. In the locked position of the pawl 232, the brackets 228 and 238 are when the solenoid is energized 207 pivoted as a unit, around the in the * rm 237 to withdraw the shoulder 243 formed by the bracket 238 from engagement with either a tooth 244 or 245, which is formed in the peripheral edge of the clutch apply plate 213, thereby engaging the

700318715.10.70

Belt clutch 195 is caused. When the clutch 195 is disengaged, as shown in iig. 7, one or the other of bolts 239 and 240 can come into engagement with the substantially horizontally arranged over edge 246 of the pawl 232 upon rotation of the driven half 214 of the coupling 195, whereby the pawl 252 out of its yerricgcliiiigocingriff üiit deis - nn 237 uös clutch engaging bracket 238 is released. The arm 23? of the clutch engagement bracket 238 is provided at its lower end with an offset elongated part 247 which is usually singly engaged with a shaft 248 which is attached to the upper free end of a cam follower 249 which is pivotably supported on a bolt 250 attached to the frame part 21 . Similarly, the lower extended end portion of the downwardly extending arm 227 of the bracket 228 is resiliently held in engagement with the roller 246 under the influence of a spring 230. Between its ends, the cam follower arm 249 carries a roller 251 which is provided by a spring 252 is loaded so that it follows a cam 253 which is attached to the hub 220 of the gear 219.

When the solenoid 207 is energized, the brackets and 238 are pivoted in the clockwise direction according to FIG. to cause clutch 195 to engage. After a Counterclockwise rotation of clutch 195 by about 60 ° (Fig. 7) the pawl 232 is moved away from the arm 237 of the bracket 238 by the bolt 239 and it remains unlocked for a rotation of the coupling 195 of about 90 °. After the initial rotation of the clutch 195 in the counterclockwise direction by 90 °, the cam 255 is rotated in the gre ^ enclockwise direction by about 60 °, see above (that the cam follower part 249 and its roller 248,

Accordingly, when the bolt 239 moves out of engagement with the pawl 232, the pawl 232 is again latched and the shoulder 243 on the arm 237 is held out of the path of the tooth 245 on the clutch engagement plate 213. During the subsequent rotation of the coupling 195 through 180 °, the bolt 240 similarly pivots the pawl 232 into the inactive division when the cam roller 251 runs on the high side of the cam 253. After the clutch 195 has rotated 360 °, the cam 253 has rotated 240 ° and the cam roller 251 continues to run on the high side of the cam 253. With the continuous counterclockwise rotation of the clutch 195 and after about 60 ° of such a rotation, the bolt 239 is again effective to disengage or move the pawl 232 from the arm 237 of the clutch engagement bracket 238. At this point in time, the cam follower roller 251 has fallen to the lower point of the cam 253, whereupon the springs 230 and 241 pivot the brackets 228 and 238 in the counterclockwise direction. Accordingly, the shoulder portion 243 of the arm 237 engages the peripheral surface of the clutch apply plate 213 to enable the tooth 245 to engage the shoulder 243, thereby disengaging the tape feed clutch 195.

In a state in which the control button 194 is pivoted downward (FIG. 7) and in this Position is held so that the solenoid 207 is held in its energized state, finds the the same sequence of operations takes place as described above, i.e. the pawl 232 is activated by each

the bolts 239 and 240 auegeklinkt and immediately thereafter again latched during the initial rotation of the belt coupling 195 mm 360th In each case, during the initial part of the subsequent or last rotation of the clutch 195 by 180 ° and after the engagement of the cam follower roller 251 with the lower position of the cam 253, the pawl 232 is again disengaged and the spring 241 becomes effective to immediately counterclockwise the bracket 238 to pivot to engage shoulder 243 with the peripheral edge of clutch apply plate 213. Accordingly, the clutch is disengaged and the work is terminated upon completion of the last 180 ° rotation of the clutch 195. Before a subsequent operation can be initiated, the button 194 must be returned to the inoperative position shown in Fig. 7, whereby the solenoid 207 is de-energized to allow pivoting of the arm 227 of the bracket 228 under the influence of the spring 230 in a counterclockwise direction to enable the latch 232 to be re-latched or re-locked to the arm 237 of the clutch engagement bracket 238.

When the tape feed clutch 195 engages for a machine working cycle becomes the cam timing shaft 208 (Figs. 4, 7, 8, 9, 12 and 13) a single turn via the gear train 216, 217 and 219 and via the cardan drive connection or Articulated drive connection 223 granted. Usually the bracket 139 (Fig. 4) is in the clock display The pivoted position shown to move the tape T through the pressure roller 140 and to cause the tape feed roller 141. Intermittent pivoting of the bracket 139 takes place under the control of a cam 257 attached to the

700318715.10.70

Shaft 208 (Pig. 9, 13) is attached. A cam follower arm 258 is pivotable on the shaft 259 supported and carries a roller 260 between its ends, which by means of a spring 261 engages with the peripheral edge of the cam 257 is pressed. The ^ eIIs S59 is in at their respective ends the Sta-Qge 47 of the yoke 46 and attached in an auxiliary part 51, which is from the rod 48 of the yoke 46 is worn. Cam follower arm 258 is on its upper free end provided with a bolt 262, which is through a suitable right-angled Slot 263 in the lower laterally offset or recessed end of the downward standing arm of the angle lever 134 extends. The cam 257, the follower arm 258 and the bell crank 134 work as a pressure control mechanism for controlling the intermittent work of the Printing mechanism formed by the bracket 139 and the roller 140. The extended end part of the Bolt 262 supports one end of a welt 264, which at its other end to a bolt 265 on the downward arm of the angle lever 134 is supported and serves to make the pressure roller 140 resilient toward the tape feed roller 141 to press. It should be noted that the bolt and slot connection 262, 263 is the separation the pressure roller 140 from the tape feed roller when the access door 88 is opened, a new roll of tape 85 can be inserted.

According to Pig. 13 the cam 257 is in the starting position or position of a full circuit, the roller 260 engaging a high portion of the cam. During the initial rotation of the cam 257 of about 70 ° in the clockwise direction, the cam follower roller 260 remains in engagement with it

the high part of the cam 257 ″ to hold the tape T by friction between the pressure roller 140 and the tape feed roller 141. During this portion of the single revolution of the shaft 208, two supplementary cams 266 and 267 (fig · 12) attached to the shaft 208 are operative to move the leading edge of the tape T from the normal rest position 84 to the printing station, i.e. into the area between the printing drum 15 and the pressure roller 14 to move. For this purpose, the drive wheel 143, which is coaxially fastened to the gear wheel 144 carried by the tape feed roller 141, meshes with the teeth of a toothed sector 268 which is supported on the part 259 for oscillating movement. Two studs 269 and 270 are fastened opposite one another on opposite sides of the toothed sector arm 2f> 8 and they each stand with the circumferential edge of the crouch 266 br ». 267 in singing riff. During an initial rotation of the squats 266 and 267 of about 45 °, the toothed sector 268 according to FIG. 12 is pivoted in the counterclockwise direction by a predetermined angle or by about half of its movement in one sighting. This limited movement is sufficient to move the leading edge of the Bendej T into engagement with the free end of a value print release arm 271 located in the path of the tape T's movement. At its other end, the release arm 271 is attached to a transverse shaft 272 which is mounted at its ends in the rods 47, 48 of the yoke 46. The amount of initial movement of the tape T is used to control the width of the tape on the printed tape. For the subsequent rotation of the squats 266 and 267 of about 180 °, the squats are provided with a dwell area or buoy area, so that the toothed sector 268 remains in the position in

700318715.10.70

which he was initially panned. The cams 16 and 267 together with the toothed sector 268 thus form a swing mechanism for controlling the movement of the volume T.

After the camshaft and the cam 2 57 have initially rotated by 90 °, the roller 260 moves with it the lower part of the cam 257 engaged, the one Represents dwell or rest distance corresponding to a rotation of about 160 °. In this position the Roller 260 is the bracket 139 (Fig. 4) pivoted counterclockwise to prevent the frictional contact Of the tape T with the tape feed roller 141 and the pressure roller 140. At the same time the toothed sector 268 is at rest in the middle of its oscillation range in one direction, whereby the forward movement of the Bendes T is temporarily stopped.

The belt T is on its path of movement through the passage between the paths 136 of a guide part 133 out, which is fastened between the rods 47 and 48 of the yoke 46. Accordingly, that will Tape T advanced between the arcuate plates 273 of the guide member 65, which at one end a rod 274 is supported, which in the spaced apart parallel lugs a cover plate 275 is attached. Each of the arcuate guide plates 273 of the guide part 65 is provided with an opening that corresponds to the opening 276 made in the guide plate 273 in FIG Fig. 3 is reproduced, and which has a size and a shape which are sufficient that the upper part the pressure roller 40 can be exposed or presented therein for the purpose of printing or printing a To enable postal printing on the tape through the postal identification plate 17 on the printing drum 15.

700318715.10.70

When the leading end portion of the tape T over the Trigger arm 271 runs during the initial 90 ° rotation of camshaft 208, arm 271 and the shaft 272 is pivoted in a clockwise direction (Pig. 2 and 4). An arm 280 attached to the outer end of the Shaft 272 is then effective to operate a normally open microscope holder 281, which is supported on the clasp 48 of the yoke 46, closing the switch to energize the clutch engagement solenoid 26 (Pig. 5).

It should be noted that immediately upon engagement of the tape feed clutch 195 and rotation of the shaft 208, a cam 282 which is carried at one end of a hub 283 attached to the shaft 208 (Pig. 9 and 15) takes effect, each of a pair of contacts 284 and 285 carried in a box supported on a bearing arm 286, which is attached to the subframe part 51. By closing the contacts 284 the motor is during kept energized for the duration of the tape feed operation while the closure of contacts 285 makes it possible makes to erase the keyboard 13 if desired, as will be explained below. On theirs At the other end, the hub 283 of the cam 282 also carries a cam 287 which is attached to it (Pig. 9 and 14) and which is effective during the initial 45 ° rotation of shaft 208 by two To close contacts 288 supported in a block attached to the bearing arm 286. The usual open contacts 288 are in line with the normally open switch 281 (Pig. 2) in the postage printing control circuit. Immediately after the contacts 288 are closed by the cam 287 directs passage of the front end of the tape T over the release arm 271 from a single circuit of the postal value printing process. It is remembered that

700318715.10.70

after the initial 45 ° rotation of the camshaft ucd, therefore, of the cams 266 and 267 (FIG. 12), the forward movement of the belt T is ended. Furthermore, after the cam 257 has been rotated 90 °, the friction contact of the strip with the pollen 140 and 141 is canceled. At this time, the plate 17 carrying the postage marks on the printing drum 15 comes into contact with the tape T and continues to advance while the postage stamp or the like is being printed on the tape.

After the pressure phase of the work process and after the camshaft 208 has rotated about 250 °, the cam 257 becomes effective as a result of the engagement of the high part 289 of the cam with the roller 260 (FIG. 13), in order to turn the bracket 139 according to FIG. 4 to pivot counterclockwise to cause frictional engagement of the tape T between the pressure roller 140 and the tape feed roller 141. At this same point in time, squats 266 and 267 (FIG. 12) complete the counterclockwise pivoting movement of tooth actuator 268 in one direction, thereby moving the printed portion of land T past cutter 290. This final advance of the tape T is sufficient to move the leading end of the tape T through an opening in the lid 23 (Figures 1 and 4) where it can be grasped to remove the printed strip from the machine after the tape has been cut by the cutter 290. The extent of such tape movement as indicated by the arc length of the high portion 289 of the cam 257, i.e. for approximately 45 ° rotation of the cam 257 and a similar rotation of the cams 266 and 267 (Fig- 12) is sufficient to leave a predetermined margin between the printed part and the trailing edge

700318715.10.70

of the strip "

In the illustrated embodiment, the rotary cutter 290 employed is preferably of the type described in U.S. Patent 3,062. The two parts of the cutting device 290 have intermeshing toothed edges and have a blade 295 and a cutting rod 292. The intermediate part 293 of the rod 292 is provided with a series of circumferential teeth. Each end portion of the rod 292 has a reduced diameter and is supported in the flanges of a bearing arm 294 (FIGS. 3 and 4) which is supported between the rods 47 and 46 of the yoke 46. In order to create a cutting edge, the toothed part is cut away 293 of the rod 292 so that J is a planar surface created, which axially isu

the cams 266, 267 (Fig. 12) of about 300 ° is the movement of the TJariiU : ■>. T terminates when roller 260 drops into low dwell portion 298 of cam 297 at cam marker 298, releasing tape T from frictional contact with pressure roller 140 and tape feed roller 141. At this point, the cutter 290 is operated under the control of a cam 304 attached to the camshaft 208 (Fig. A) . For this purpose, an arm 305, which has a shoulder 306 formed at right angles to it, is attached to the end of the cutting rod 292 adjacent to one end of the toothed part 203. The arm 305 is pivotally attached at its lower free end at 307 to one end of a link 308, the other end of which is pivotably supported on a bolt 309 which is attached to the upper end of an arm 310 of an angle lever 311 which is attached to the shaft 259 is pivotally mounted. The other arm 312 of the bell crank 311 carries a roller 313 which is held in engagement with the peripheral edge surface of the cam 304 under the influence of a relatively strong spring 314 which at its one end in the projection 306 of the arm 305 and at its other end in a suitable bearing arm 315 is attached, which is attached to the rod 48 of the yoke 46. In the usually inoperative or fully circular position of the cam 304 shown, the planar surface of the toothed portion 293 of the cutter 290 is in a plane parallel to the path of travel of the tape T to permit movement of the tape T thereover.

It should be remembered that during the initial rotational movement of the cam 287 (FIG. 14) of about 45 ° the contacts 288 are temporarily closed when the leading edge of the tape T hits the trigger arm 271

700318715.10.70

(Pig. 2) pivoted so that the usually open microscope holder 281 is closed, thereby energizing the clutch apply solenoid 26. After the termination of the individual cycle of the postage printing process and immediately after the cutting device 290 is actuated, the cam 257 (Fig. 13) effective in turn to pivot the bracket 139, to lift contact of the tape T between the pressure roller 140 and tape feed roller 141 »Terminate or complete cams 266 and 267 then the oscillating movement d <= »s tooth sector 268, making it clockwise in the usually ineffective or full cycle position according to Pig. 12 so that the tape T in the Pig. 4 starting position indicated at 84 is withdrawn.

The extent to which the tape T is withdrawn and the usual fiuhdividing the leading edge of the band T, which is indicated at 84, is by setting an auxiliary cam from section 316 (Pig. 13) in order to enlarge the lower dwell area or rest area 298 of the cam 257 or to shrink. Such an adjustment of the cam sector 316 controls during the Rotation of the cam 257 in degrees reduces the frictional engagement of the tape T between the pressure roller 140 and the tape feed roller 141 during the retracting phase. Through this attitude is the length or extent of the edge between the identification imprint and the leading edge of the Band T ensured.

In the Pail that the keyboard 13 should be erased after one or more operations of the The tape feed and tape printing becomes the Rpcketell delete button 155 (Pig. 1, 7, 10 and 11) according to

700318715.10.70

down in the in Pig. 1 indicated extinguishing position pivoted. As explained above, when the button 155 in Fig. 7 is in the erase division after is pivoted down, the cam lug 181 of the main body part of the button 155 is effective usually open microscope holder 285 to close. The macros are contained in 185 the switch contacts 285 (Pig. 15) and a normally open microswitch 320 (Figs. 5 and 6).

It should be remembered that when initiating a tape feed process, the crouch 282 on the Camshaft 208 (Pig. 9 and 15) takes effect immediately, the contacts 285 to close and they for the Circuit of the tape feed process closed keep. Near the end of the postage printing process the microswitch 320 is closed, thereby energizing the solenoid 3 80 for engagement of the extinguishing clutch 70 for a keyboard erase process is caused to the type wheels in the printing drum 15 to reset to the zero position.

For this purpose, a gear wheel 321 meshes with the idle gear wheel 34 in the Postwertdruekantriebszug (Pig. 5 and 6). The gear wheel 321 is attached to one end of a sleeve 322 which is rotatably supported on a shaft stub 323 is, which: "on the machine frame part 22 attached is. The sleeve 322 carries a cam 324 at its other end, which on approximately the last 45 of the postage printing circuit is effective to the Microswitch 320 to close. It is reminded that immediately when the keypad clutch 70 (Pig. 5) engages the cam 73 (Fig. 5 and 6) takes effect to keep the microswitch 170 closed, ue the motor during a full To keep the working circuit of the clutch 70 energized.
