When the print head 63 is in the printing position, is the pivot pin 135 in-the in interrupted Lines 135 'shown position and in this position the print head 63 is perpendicular to the pressure plate 69. If the Actuating part 81 is released, causes the spring unit 82 '(Fig. 1) the actuating part 81 to pivot counterclockwise, whereby the lever 133 clockwise is driven and the ■ print head 63 in the in Fig. 7 returns, and at the same time the feed wheel 64 is driven by the pawl 134 and pushes the multilayer web 30 further a distance corresponding to the length of a label 36. In the embodiment According to FIG. 7, the actuating part 81 does not have a toothed segment ·; 82 on.

The device of the embodiments according to FIG. 1 and Figures 3 to 6 and Figure 7 is made primarily of molded plastic material. The intermediate frame 55 is made preferably made of steel. The operating part 81, the gear 66 and the lever 67, the ratchet wheel 65 and the feed wheel 64, an essential part of the printhead 63, the housing sections 52, 53 and 54, the hub 113 and the ball bearing rails 94 and 95 are made from a suitable molded plastic material. The connecting link 131 and the lever 13: in Fig. 7 are also made of plastic material.

In practice it has been found that in some cases smaller amounts of rubbery pressure-sensitive Adhesive will remain on the web of liner 32 after the labels have been peeled off. If it does

20980 * 7/0301

this rubber substance can be transferred to the feed wheel when the carrier material web with the feed wheel 64 comes into contact, which may cause the device to malfunction if it continues to be used.

In both embodiments of the invention, the feed wheel 64 has a web contact surface 116 which, with a Coating 116 '(FIG. 5A) is provided with light-adhering or release properties which are sufficient for a transfer of, if necessary rubber or pressure sensitive adhesive present on the web of substrate 32 on the feed wheel essentially delayed or prevented. Preferably, the web contact surface of the feed wheel should be pressure sensitive Tape (e.g. one under the trade name 3M Transparent Tape 5910 known tape) slightly after this on the feed wheel under a pressure of 0.70 kg / cm 2 to 5 Has been applied for seconds. ,

A particularly preferred method, in which the phenyloxides (e.g. known under the trade name "Lexan") from a metal or an organic polymeric plastic, such as polyacetal resins (e.g. resin known under the trade name "Delrin"), polycarbonate resins (e.g. resin known under the trade name "Lexan") Noryl "known material"), under the name "nylon". known polyamides (e.g. one of the polyamides known under the trade name "Nylafil", ¹¹ Zytel "or" Nylatron "), acrylonitrile-butadiene-styrene resins (e.g. the resin known under the trade name" Cycloac-ABS ßesin "), unsaturated polyester Mold resins or the like produced feed wheel is to receive improved release properties, consists in providing the surface of the feed wheel that comes into contact with the web with an uninterrupted adhesive coating of a resin-like coating compound which has a lower surface energy than the polymeric carrier material

which enforce the cutouts 184. Fig. 31 shows a fastening part in the form of a gripping ring 186 which comprises such a connecting piece 185. A compression spring arranged on the connection piece 185 187 presses against the frame plate 155 and the hand ring 186. If the device is used for a long time, the nozzle tilts! 185 to getting longer. The compression spring 187 ensures that the frame plate 155 is always firmly held on the housing section 152 ·. Since the nozzle 185 is a much smaller one Diameter than the cutout 184, the arrangement j of the frame plate 155 in relation to the housing section 152 takes place by dije Arrangement of the lugs 183 in the corresponding holes 182. '

The frame plate 155 is provided with a pair of elongated Aus-J cuts or unilaterally open slots 188 and a pair I of oppositely directed elongated cutouts or one-sided j tig open slots 189 provided. The slots 188 and 189 'are connected to larger recesses 190 and 191, respectively. Ball bearing rails 192 and 193 directed in opposite directions engage in the corresponding recesses 190 and 191, respectively. The J" Print head 170 has a print head frame 194, which mit.einim Pair of oppositely directed ball bearings rails 195 and 196 is provided. A ball bearing strip 197 engages in the appropriate one Ball bearing slides 192 and 195, while a ball bearing strip 198 is taken up by the matching ball bearing rails 193 and 196. The ball bearing rails 192 and 193 are substantially trough-shaped. When the ball, Bearing rails 192, 193 are in the position shown in FIGS. 10 and 11, they engage in the frame plate 155.

In the device 150, a multilayer web: 203 is used. In the case of the multilayer web 203, this adheres ^; Label material 204 releasably on a carrier material 205. The label material 204 is cut transversely by incisions or slits 206 which extend over the entire path of the label material 204, whereby this is divided into a series of labels 207 butting against one another. The multilayer web 203 is on a cylindrical core 208 with circular. ' shaped diameter made of cardboard or some other suitable material. The role of the multilayer ^; The web is attached to a spool 209. The coil 209 loads _; stands from a substantially equal disk 210 with. one ι

central bore 211. The disk 210 is provided with a plurality of pins 212; provided, which are arranged at equal distances from the central bore ■ 211. The . Disk 210, the bore 211 and the pins 212, which are formed in one piece with the disk, are formed in an injection molding device in one operation during the manufacture of the disk 210. The spool 209 further has a hub 213. The hub 213 has a central tubular hub portion 214 which is connected to a rear wall 215 (Fig. 32). The pins 212 engage mating holes 212 ¹ in the rear wall, thereby keying the disc 210 and hub 213 for rotation as a unit. A plurality of flexible, resilient, cantilever fingers 216 are arranged at a distance from the hub section 214 to the outside and connected in one piece to the rear wall 215. The fingers 216 extend slightly outwardly and away from each other when the core 208 is placed on the hub. The free ends of the fingers 216 have projections 217. Each of the protrusions 217 is provided with two tapered surfaces 218 and 219. The surface 218 facilitates the application of the label roll to the hub 213 and the surface 219 forms one.

When the supply roll is placed on spool 209 and when the spent core 208 is removed, fingers 216 flex inward. The pin or the connecting piece 181 passes through the bore 211 in the disc 210 and a bore 220 in the Äaben_sabschnitt 214. A fastening part 221 attached to the end of the connecting piece 181 prevents the coil 209 from slipping off the pin or the connecting piece 181 and from loosening the labe 213 from the disc 210 so that the pins 212 do not lose their connection with the holes 212 '. The hub 213 is likewise '__ if made by injection molding. The disk 210 ^: delimits a band of the feed path, so that the multilayered path 203 that runs from the bollard starts its path in precise alignment with respect to the pressure plate 174 and the feed wheel 171.

An actuating part 222 is in the form of a pivotably actuatable lever which is fastened to a holding structure 222s (FIGS. 4 12) which has a pin 223 which engages in an eccentric 224 in the form of a bushing. The actuating part 222 is pressed counterclockwise by a spring unit 225 according to FIGS. 8 and 11. Essentially corresponds \ the spring unit 225 holds a compression spring 226. [

The actuating part 222 carries a gear or a tooth-f segment 227, which has a recess 228 on white-1, which is passed through a! missing tooth is formed. The ten segment 227 meshes with the tooth segment 229 of the gear wheel 172. The tooth segment 229 has a large tooth 230 (FIG. 17) which meshes with the tooth adjacent to the recess 228. Since the tooth 230 is only in the recess 228 can intervene, the actuating part can only be installed in the correct position in relation to the gear wheel 172 will. The gear -172 also has a tooth segment

The toothed segment 231 is provided with a recess 233 which is formed by a missing tooth, and the toothed segment 232 has a large tooth 234: which engages in the recess 233 so that the print head 170 only can be installed in proper position with respect to gear '172. When the handle 159 is held by the operator's hand, the operator's fingers can pivot the actuator 222 counterclockwise (FIGS. is rotated sense and in turn ^{brings the print head 170 in printing position 1} in relation to a label 207 that is on the. Pressure plate 174. · By releasing the actuating part j 222, the spring 226, the actuating part 222, the gear
172 and the printhead 170 as well as other components to be described later return to their original positions. The G-housing sections 152 'and 154 have stops 151'. j

A drive shaft 235 is with the. Gear 172 formed in one piece. A holder 236 in the form of a .Tube or a = tubular bearing is in a suitable manner in an opening
237 ¹ fixed in the frame plate 155, as best seen. j Fig. 18 can be seen. The feed wheel 171 is provided with a plurality of pairs of transversely spaced apart teeth 171 'which engage the path of the carrier material 205, as will be described in more detail later.
As FIG. 21 shows in exaggerated size, the teeth 171 'are beveled at the front in order to be able to grasp the feed edges in the path 205. The feed wheel 171 has an edge 238

are. The edge 238 consists of the multilayer web contacting annular circumferential sections "or beads 238 'and an intermediate space or gap formed by an annular section 238" with a smaller diameter than the sections 238'. As FIG. 36 shows, the sections 238 ^{1 have} webs 116a which are provided with relatively sharp edges in order to produce essentially only a line contact between the web 205 and the webs 116a. Gaps in the form of grooves 115a between the stems 116a and section 238 "reduce the area of contact to a very small percentage, less than $ 50, and as shown, preferably to less than 10?" of the circumferential area which would otherwise form the surface area of the feed wheel 171. Adhesive, gums or the like adhering to the feed wheel 171 collects in the grooves 115a, but this becomes the outer diameter of the feed wheel 171, which is determined by the webs 116a , not increased; an increase in the diameter would be disadvantageous in that it would increase the length of the path to be fed by the feed wheel 171 each time the actuating part 222 is actuated. For example, the depth of the grooves 115a is about 0.635 mm. Each section 238 ^! has one hundred and nineteen ridges 116a. Although the webs 116a are sharp, they do not cut into the path 205. The feed takes place by the teeth 171 'resting on the path. In addition, the Umfarigsflache d3s feed wheel 171 is preferably with a liquid or permanent coating A suitable lubricant is added to the material that retards the build-up of glue, rubber, or the like, or the plastic from which the feed wheel 171 is made. An annular wall 239 connects the rim 238 to the honeycomb portion 240. The hub portion 240 is with a bore portion

The bore portion 242 is provided with protrusions, which consist of a large number of grooves or grooves and ribs 244 which extend in the axial direction; put. A rolling contact one-way clutch 243 is arranged in the bore portion 242. The inner diameter of the bore ⁱ abschnitts'242 formed by the ridges of the projections, that is, ■ ribs is limited 244, is smaller than the outer diameter of the clutch 243. The clutch 243 is fitted by pressing into \ bore portion 242 and the ribs 244 give in slightly and hold the coupling 243 in the position shown in FIG. 18 ^! position shown in the friction seat. The coupling 243 is provided with a plurality of rollers 245 which on the outer: ren cylindrical surface 246 with a circular cross-section; the one-way clutch 243 acts as a bearing and enables the feed wheel 141 to rotate

clockwise according to FIGS. 7 and 17, but prevents a! Counterclockwise movement. For example, purpose * A coupling such as that made by The Torrington may be used with the device according to the invention Company, Torrington, Conn., USA, and in their catalog RC-6, 1969, as Roller Clutch Catalog No. RC-081208 is described.

A small portion of the coupling 243 is illustrated in FIGS. 19 and 20. In the one shown in FIG Position is a rotation of the feed wheel 171 counterclockwise by the coupling 243 prevented that the rollers 245 are in clamping contact with appropriately beveled ones Surfaces 247 are, while according to FIG. 20, the feed wheel 171 rotates in the direction of arrow A and the Do not roll 245 between surfaces 247 and surface 246

The clutch 243 is spring-loaded in that springs 248 continuously press the lugs 245 against the surfaces 246 and 247 so that any idling of the clutch 243 is negligible and substantially less than when a pawl is used. The feed wheel 171 also has tracks 249 which are connected to the edge 238, the wall 139 and the labe 240. The inner circumference of the hand 238 on one side of the wall 239 is provided with a plurality of lips 250 and ribs 251 in an annular arrangement. The interior 250 and ribs 251 extend in the axial direction. A ratchet wheel 252 (FIG. 17) is provided with a plurality of ratchet teeth 253. The ratchets 253 are formed integrally with one side of a wall 254. An annular wall or a flange 255, which has a multiplicity of recesses 256 arranged at equal distances from one another, is provided with a multiplicity of interior spaces 257 and ribs 258. The interior 250 and ribs 251 and the interior 257 and ribs 258 have the same slope and are complementary with respect to one another. The ratchet wheel 252 also has an annular hub 259 with an inner bore 260 (FIG. 18). The bracket 236 can extend into the bore 260 in a position where the end of the hub 259 contacts an end of the coupling 243. In this position, the ribs 258 and 257 of the ratchet wheel 252 engage in the complementary grooves 250 and ribs 251 of the feed wheel 171. 18, the position of the ratchet wheel 252 relative to the feed wheel 171 can optionally be changed. Such a change results in a change in the orientation of the label 207 in the printing area between the print head 170 and the pressure plate 174, as well as a change in the position to which the web 205 and the foremost label 207 are advanced in relation to the release device 175.

line 307 on one side of the axis 308 of the connecting piece 303 and tends to have 'the arm 302 and the should 293 it carries in hers to press the extreme clockwise shifted position, as best seen in FIG. In Fig. 21 are the Arm 302 and the 293 in their outermost, counterclockwise direction shifted position and the tension spring 304 exerts a force along the center line 309 on the other side of the axis 308 off to arm 302 and roller 293 in the position shown to keep.

As can be seen from FIG. 10, the operator can move the slider 288 by exerting a force to the left on the projection 288 ¹ into the position shown. Not only the ball 293, the guide 300, the ana 302 carrying them, the associated arm 286 and the brake component 283 are moved into the position shown in FIG. 10, and thus the should 293, the guide 300 and the brake mechanism 270 instead of being actuated, the tension spring 304 (FIG. 21) also holds these components firmly in this position in order to be able to load the device 150 easily. As can be seen from FIG in the arm 297. If the device has now been provided with the label supply roll, the arm 297 acting on the axis 291 causes the arm 302 to pivot counterclockwise as shown in FIG is returned in cooperation with the multi-layer label web 203 and the feed wheel 171, so that the guide 300 in guide contact with the side edge of the web 203 'and the brake component 293 in its in F Fig. 23 shown active; position is moved. The subsequent actuation of the actuating part 222 causes the arm 297 to move relative to the axis 291, but the arm 297 has no effect on the axis 291 due to the slot 296. The slider 288 and the associated components from the in 10 and 21 changed to the position shown in FIG. 23 _;

Runs from area Z1 the multilayer web 203 further around a roll 323, which consists of a plurality of rolls, for example three rolls 177. The rollers 177 are free to rotate on the pin 176. By the presence of a multiplicity of roles 177 there is no tendency for these rollers to seize onto pin 176, which would be the case if only one long roller would be provided. When the multilayer web 203 has run around the roller blind 323, a label 207 is placed between the pressure plate 174 and the print head 170 are arranged. Fig. 10 shows one of these labels 207 that is almost entirely off the web 205 of the carrier material is detached and ready to be applied by the application device 173. The application device-173 has a roller which is rotatably mounted on a pin 325 attached to the frame plate 155, although other types of Aufbringeein directions, if desired can be used. A detachable fastening part 326 holds the applicator 173 on the pin 325. In the position shown in FIG. 10, the multi-layered one is running Track 203 partially around one end of slider 288 and partially around roller 293 and from there partially around the Feed wheel 171. The axle 178 carries a roller 327 (Fig. 8). Between the hub 285 and the frame plate 155 and a roller blind 328, which is located between the sliding piece 288, for example in the position shown in FIG. 22, is the track 205 in sliding contact with the end of slider 288 and in roller contact with rollers 327 and 328.

Of the Hub portion 409 is also provided with an extension 423 and a shoulder 424 in the form of a flange, the is aligned with respect to the bores 411 and 412. The lug 424 prevents the paint roller 401 from hitting the nozzle 401 'is placed in the wrong direction, in which the resilient finger 421 would not cooperate in the groove 422 and the paint roller 401 could slip off the nozzle 401 '.

Fig. 9 shows a multilayer web 203 which is a Represents improvement of known railways. Groups 425 with incisions or cuts are spaced in the longitudinal direction

509807/0301

Distributed over the length of the multilayer web 203. Although in the illustration according to FIG. 9 two spaced-apart groups 425 of incisions are arranged between the incisions 206 forming the end edges 207, more than two groups 425 can be provided in each label 207: and although the groups 42.5 essentially in the middle ^{: are arranged} between the end edges of the individual labels 207, they can also be provided at other locations. Each group 425 of incisions is essentially T-shaped and has a pair of incisions or cuts 426L aligned in the transverse direction in the label material 204 and preferably penetrating it and a pair of incisions or slots 426S aligned in the transverse direction in the carrier material 205. The individual pairs of incisions 426L and 426S are separated from one another by webs 427L and 427S, respectively. Incisions or slits 428L and 428S running in the longitudinal direction extend in and preferably through the label material 204 and through the carrier material 205 in each case towards the corresponding webs 427L and 427S. Furthermore, two incisions or slots 429 running in the longitudinal direction are provided; which extends into the label material 204 and preferably through it via the incisions 206 into the end edges of the labels 207. The incisions 429 only cut through the label material 204. The two incisions 426S and the incision 428S of a group coincide with the corresponding two incisions 426L and the incision 428L of the group 425 Attacking cuts jn 428S, the portion of the web between the adjacent ends of the two cuts 426S and incision 428S tears, creating a hole in the web of liner

205 is formed. A tooth 171 'is preferably almost as wide as the combined length of the adjacent cuts 426S and the intervening web 427S, so that a substantial Part of the length of each cut 426S may form a drive surface.

To load the device 150, the housing section 153 is first released by moving the projection 360 essentially to the right according to FIG. 72. Then the projection 288 ^{1 is} moved substantially to the left as shown in FIG. 10 in order to bring the braking part 283, the roller 293 and the guide 200 into their inoperative I position. If there is a consumption-i on the spool 209. The core 208 is located, it is removed by hand and a new supply roll is pushed onto the hub 213. The front '. The end of the multilayer web 203 is pulled over the resilient device 310 and into the. Area Z1 pushed, as on ^! - Best seen in Fig. 10. From there, the web 203 is drawn around the roller 323 around the release device 175, from where it runs around the end of the slider 288 and under the roller 293. From here the path 203 is partially guided around the feed wheel 171 and through the area Z2. All of the just described threading of the multilayer web 203 can be carried out without _; Removal of any label 207 from the web of carrier material 205 can be performed. The print head 170 can now be set to print the selected characters on the label 207, which is aligned with respect to the pressure plate 174. Upon the first actuation of the actuator 222, the gear 172 causes the arm 297 to pull the slider 288 to the right in FIG To bring the braking member 283 into its operative position, as shown in FIG. 23, and to cause the guide 300 to move into its operative position shown by broken lines 300PL. Because through the first ' -50-

609807/0301

If the actuating part 222 is actuated from its starting position, the gear wheel 172 is driven, which in turn brings the print head 170 in pressure division with respect to the pressure plate 174, the label 207 located at the printing point or in the printing area is printed. When the print head 170 is in cooperation with the pressure plate 174, the drive end 269 of the pawl 265 has moved into a position next to the next following tooth 253 of the ratchet wheel 252. When the actuating part 222 is released, the compression spring 226 of the spring unit 225 causes the actuating element 222 to pivot counterclockwise (FIG. 10), whereby the gear wheel 172 and the pawl 265 are moved clockwise. This movement of the pawl 265 causes the feed wheel 171 to rotate clockwise. As a result of the interaction of the feed ^{wheel 171 and the bolt 293, the teeth 171 f} tear the section of the carrier material 205 between the ends of the incision 428S and the adjacent ends of the incisions 426S. The teeth 171 'engage the drive surfaces formed by the indentations 426S and advance the web 203 as the feed wheel 171 rotates. The operation is completed when the actuating part 222 has returned to its starting position. During the ongoing operation of the device 150, labels 207 are successively peeled from the web of carrier material 205. It turns out that with every activity and every. When the actuating part 222 is released, the print head 170 is first brought into printing positions in relation to a label 207, whereupon this label is advanced into a position shown in FIG . The foremost label thus adheres only slightly to the web of the carrier material 205 with its rear end until it has been applied to an object.
