Abstract

An integrally complete composite-tape placement head for direct attachment to a host gantry type of machine, which tape placement head is designed to precisely apply preimpregnated fiber reinforced tape to a work piece. The tape is initially supplied in the form of a roll with a suitable backing. The tape is automatically peeled from the backing by a separator mechanism and thereafter applied to the work piece. A powered cut-off device is actuated by a photoelectric mechanism to sever the tape at a proper location and at a preestablished angle. The determination of the pre-established angle is accomplished by a photoelectric edge sensing mechanism.

22 Y Y2/ l I NVENTORS HARALD E. KARLSON ETHR/DGE E. HARDESTY ATTORNEY BACKGROUND OF THE INVENTION This invention relates in general to certain new and useful improvements in composite-tape placement heads, and more particularly, to composite-tape placement heads for direct attachment to actuating equipment.

In recent years, reinforced plastic composite materials have achieved increased prominence and have been used in the manufacture of a variety of products which are normally formed of heavy metals and other counterpart materials. For example, pipe, motor casings and various other types of structural members which were formerly fabricated from the heavy metals are now being produced in the form of reinforced plastics.

Many of the structural members used in the air frame industry are presently formed of aluminum and other light weight metals. However, there has also been a recent transition to the employment of reinforced plastic components. Conventional filament winding systems have been employed in the fabrication of these reinforced plastic components. In order to increase productivity in the manufacture of these components, resort has been made to the use of tape application equipment.

However, the extant tape laying equipment is ineflective in many cases because the filament reinforced tapes are often difficult to effectively handle due to their modulous of induced rigidity. Accordingly, the unspooling of a three inch tape, for example, presents considerable problems in maintaining proper tension on the tape as it is applied to the work surface. The convolute windings of the tape tend to expand and unwind in the manner of a released clock spring. The various tapes presently employed inherently have some variation in boardiness and tack and the lay down pressure on the work piece is not variable to adjust for these variations in the tape.

One of the most serious problems encountered in the use of the conventional presently available tape heads resides in the failure of the head to properly sever the tape at a desired location, and at a preselected angle with respect to the work piece.

It is, therefore, the primary object of the present invention to provide an integrally complete compositetape placement head for direct attachment to other actuating equipment.

It is another object of the present invention to provide a tape placement head of the type stated which can be actuated both in cooperation with and independently of the host actuating equipment.

It is a further object of the present invention to provide a tape placement head of the type stated which is highly reliable in its operation and which can be used with a wide variety of reinforced plastic composite tapes.

It is another object of the present invention to provide a tape placement head of the type stated which includes all of the tape forwarding, tape-placement, backing-film retrieval, and tape-cut-off mechanical and drive functions.

It is yet another salient object of the present invention to provide a tape placement head of the type stated which is constructed with a high degree of precision and thereby provides'an extremely close dimensional accuracy with minimal tolerances.

With the above and other objects in view, our invention resides in the novel features in form, construction, and arrangement of parts presently described and pointed out in the claims.

GENERAL DESCRIPTION Generally speaking, the present invention relates to a filament tape applicator (often referred to as a tape head or tape placement head) which is used on a selected type of host actuating equipment, such as a gantry machine. The tape placement head is normally shifted through X and Y coordinate axes through the action of the gantry machine. In addition, the tape placement head is constructed so that it can shift along additional axes with respect to the gantry machine.

The tape placement head of the present invention generally includes a relatively large major support bracket for removable securement to the host actuating equipment. A motor is suitably mounted. on the supporting frame and is connected to a drive mechanism for rotating the tape placement head about a depending flange formed on the host actuating equipment. The drive mechanism is designed to rotate the entire tape placement head in a full arc in either direction. Thus, if tape was being placed upon a work piece during the movement of the tape placement head in the X axis, the host actuating equipment would be programmed to automatically stop at the end of the tape application cycle. At this point in time, th motor is actuated to rotate the tape placement head 180. The host actuating equipment would shift the head laterally in the Y coordinate axis so that a next strand of tape can be placed adjacent to the previously deposited strand of tape.

Also mounted on the supporting frame is a shaft for removably receiving a roll of filament type tape such as boron tape. The tape is secured to a backing film, generally formed of paper, and is preferably preimpregnated with a suitable resin curable matrix. Furthermore, the supply spool is maintained under a proper degree of tension as the tape strand is paid out from the spool.

A separating mechanism is provided to peel away the backing from the pre-impregnated tape and the backing is retrieved onto a driven wind-up storage spool. The relative position of all of the spindles in the tape placement head have been arranged to provide an alternate path for the tape-backing, if desired. After the backing web has been separated from the composite tape, the tape passes through a cutting mechanism to be hereafter described. The tape is again brought into contact with the backing web prior to engagement by a laydown roller. The backing web which is operatively interposed between the lay-down roller and the tape prevents the tacky resin matrix from being accumulated on the lay-down roller and subsequent soiling thereof. Thus, the lay-down roller is shielded by reutilization of the backing web. In some reinforced composite tapes, it is not necessary to separate the backing web from the tape prior to cutting and the backing web would then be separated from the tape at the lay-down roller.

As indicated previously, the supply spool is driven. The unspooling of a three inch wide tape, for example, can only be practically accomplished through physical containment and restraint due to the modulous induced rigidity. Otherwise, the convolute windings would tend to expand and unwind in the manner of released clock spring. The tape which is brought into contact with the backing web and the lay-down roller is then push-fed against a curving chute which terminates at the point of tangency with a substrate work surface.

A cut-off assembly or so-called shear mechanism or shear assembly is also mounted on the frame and is pneumatically operated by paired cylinders. The shear assembly is capable of cutting a 3 inch wide filament-tape through an arc of i 45 normal to the tape center line. The shear assembly is driven by a stepping motor which is controlled by a complex edge-sensing mechanism to be hereinafter described. The shear assembly comprises a combination of a shearing type blade and teflon anvil. The blade is attached to a fixed shear frame member and the teflon anvil is attached to a moving platen.

Also mounted on the frame is an edge-alignment sensory assembly which consists of a pair of photocells mounted on a linkage mechanism that swings the cells through an are :t 45 from the tape center-line. The sensing mechansim is driven by and with the shear mechanism so that the relationship between these two members is kept constant. As one of the photocells of the edge-alignment sensory assembly picks up the reflection of its integral light source from the retroreflective tape, a signal to the shear drive motor causes the drive motor to shift the cutting mechanism in the direction corresponding to the cells position. When the second cell is activated, the shear drive mechanism is stopped and a solenoid valve controlling the shear's cylinders is energized thereby causing the tape to be severed.

A deceleration photocell is aimed approximately two inches ahead of the edge-sensing photocells. When this latter cell is activated by its light beam being reflected from the retro-reflective tape, it signals the machine to slow to a creep speed. This slow-down insures that the edge-alignment sensory assembly will have sufficient time to accurately rotate into position.

Also mounted on a frame is an infrared type of electrical heating device utilizing a quartz lamp as the heat source and an elliptical reflector to concentrate the heat in a small band at the focal point of the reflector. this band being transverse to the direction of movement of the tape. The quantity of heat is controlled by a transformer or a rheostat. The heating device is also designed to rotate away from the tape whenever the tape drive is stopped, in order to prevent localized heating of the tape, thereby providing any premature cure of the tape.

DETAILED DESCRIPTION Referring now in more detail and by reference characters to the drawings which illustrate a preferred embodiment to the present invention, T designates a tape placement head which is secured to a somewhat conventional gantry-type machine in the manner as illustrated in FIG. 1. In order to more fully understand the operation of the tape head, a brief description of the gantry-type machine is provided.

By reference to FIG. 1, it can be seen that the tape head T is mounted on a gantry machine G having a gantry 1 shiftable along a longitudinal axis X.'Furthermore, the tape head is mounted on a support plate or carriage 2 which shifts transversely with respect to a work platform 3 forming part of the gantry machine G. Thus, the support plate 2 shifts in a transverse or Y axis. The support plate 2 is also shiftable vertically in a Z coordinate axis. Thus, the tape head T can be shifted longitudinally with respect to a work piece W in order to apply longitudinal strands of tape to the work piece W. In like manner, the support plate 2 is shiftable transversely so that the tape head T can be shifted in order to apply a next adjacent strand of tape material. Finally, the support plate 2 is shiftable vertically in order to locate the tape head T at a proper distance with respect to the work piece W.

By further reference to FIG. 1, it can be seen that the tape placement head T is also rotatable in an axis C in order to apply tape strands to the work piece in an axis which is angularly displaced with respect to the X or Y axes. Furthermore, the tape head is shiftable accurately with respect to the Y axis in order to provide an axis A Finally, while the work piece W is illustrated as being located on a flat work surface, it should be recognized that the work piece W may be rotatable along its axis which is parallel to the X axis in a rotatable coordinate axis A,.

By reference to FIGS. 2 and 4, it can be seen that the tape placement head T integrally includes a bearing retaining ring 4 which forms part of a yoke 1 l. A support ring 5 is mounted on the underside of the bearing retaining ring 4 in the manner as further illustrated in FIGS. 2 and 4 and a drive ring 10 is mounted in cooperative relationship to the support ring 5 and the retaining ring 4. The drive ring 10 is provided with an exterior peripheral ring gear (not shown) and mating with a pinion gear 13 driven by an electric motor 14, the latter being mounted on a bracket 12, in order to selectively rotate the entire yoke 11 in 180 arcs. Thus the entire tape placement head T can be rotated with respect to the work piece W and with respect to the gantry machine G. A pair of stops 15 are provided in order to hold the tape placement head T in position. Furthermore, the stops are provided with suitable magnetic or other type locking mechansims in order to maintain a rigid pattern for the tape placement head T, while the latter is shifting during the application of the tape.

The yoke 11 comprises a pair of oppositely disposed vertically depending legs 16 which are integrally formed with the support ring 10 in the manner as illustrated in FIG. 2 and the two legs 16 are connected by a plurality of transversely extending support bars 17 which are welded to or otherwise rigidly secured to the legs 16. At their lower end, the legs 16 are integrally merged into enlarged hubs 17 which retain suitable roller bearings. 18 for journaling a transversely extending yoke shaft 19. Thus, it can be seen that the shaft 19 is pivotal with respect to the legs 16.

Pivoting on the shaft 19 and extending forwardly thereof, that is in the direction of movement of the tape head T are a pair of transversely spaced support arms 20 and 20, as illustrated in FIGS. 2 and 7. Secured to the support shaft 19 and extending forwardly therefrom is a cast metal side frame 21 which is more fully illustrated in FIG. 3. It can be seen that the side frame 21 has a forwardly extending horizontally located arm 22 and a somewhat triangularly shaped cast section 22'.

By reference to FIGS. 2 and 3, it can be seen that the major portions of the components on the tape head T are carried by the arms 20 and 20 and the slide frame 21 so that, in essence, substantially all of the components of the tape head T are pivotal with respect to the yoke 11 about the yoke shaft 19. A pair of microswitches 23are located on the arm 23 of the side frame 21 and indicate to a central control unit the relative vertical position of the tape placement head T. In essence, these micro-switches 23 indicate whether or not the tape head T has been pivoted upwardly to a shifting position or downwardly to a tape laying position.

lntegrally formed with one of the lowermost transversely extending support bars 17 are a pair of rearwardly extending clevis forming brackets 24 for pivotally retaining a hydraulic cylinder 25, the latter being conventional in its construction and, therefore, not illustrated in any'further detail herein. A piston 26 is operable by cylinder 25 and secured to the lower end of the piston 26 is a coupling 27 for pivotal securement to a bracket 28. It can thus be seen that the bracket 28 is formed with side frame 21 and is secured to the coupling 27 through a pivot pin 29. Thus, it can be seen that when the hydraulic cylinder 25 is actuated, the piston 26 will cause the link 27 to shift the cast side frame 21 and the forwardly extending arm 20 upwardly about the yoke shaft 19, thereby raising the assembly with re- 1 spect to the main support yoke 11.

lntegrally formed in the upper end of the side frame 21 in an enlarged hub 30 and joumaled in the hub 30 is a transversely extending reel spindle 31 for supporting a pay-off reel 32. The reel 32 or so-called spoolf contains wound filament reinforced composite tape 33 suitably secured to a removable backing 34. As indicated previously, the tape is of the reinforced composite type and contains and may be predmpregnated with a suitable resin curable matrix. The reel 32 is conveniently removable from the spindle 31 by means of a rotatable locking assembly 35. Furthermore, a magnetic brake 36 is secured to the outer end of the spindle 31 to provide a back tension on the spindle 31 and, hence, on the pay-off reel 32.

The backing paper may be conveniently formed of any suitable material which is inert with respect to the tape and any pre-impregnated matrix and which is conveniently removable from the tape by means of peeling. For example, the backing may be formed of paper or a thin flexible plastic material such as polyethylene, mylar or the like.

The composite tape is generally formed of a series of longitudinally extending substantially parallel strands of filamentary reinforced material such as fiberglass, lithium, boron, quartz or grown whisker crystals, etc. In addition, metal wire may be interspersed with the filaments in the event that it is desired to add some type of metallic body to the reinforced structure.

Any of a number of commercially available resin matrix materials can also be employed for preimpregnating the tape. The matrix should be capable at some stage of the process of being liquidified and softened for a period of time and also should be sufficient to flow around the filaments forming the tape. In addi-' tion, the matrix should be capable of achieving a rigid stage of a complete polymerization to become a rigid solid and should also possess ability to adhere to the reinforced material. Some of the suitable matrix materials which can be employed for pre-impregnating the tape are many of the thermoplastic resins such as polypropylene, polycarbonates, etc. In addition, some thermosetting resins, such as the polyesters. Many of the phenolics and epoxies can be used as well.

The pay-off reel 32 is designed to carry either three inch or eight inch inside diameter cores and a wide number of tape widths. In order to account for tape reels of different widths, a side plate 37' having a teflon coated inner surface is disposed against the tape reel. A number of washers can also be disposed on the reel spindle 31 between the side plate 37 and the locking nut assembly 35.

The composite of the tape 33 and the backing 34 is then passed between a pair of tape guides ,38 and trained through an idler pinch roller 39 and a drive roller 40 in the manner as illustrated in FIGS. 2 and 4. The combination of the drive roller 40 and the idler pinch roller 29 provides a means for feeding the tape through the system at a preselected rate. The pinch roller 39 is rotatably secured to a pivotally mounted arm 41 which is biased toward the drive roller 40, by means of a set screw mechanism 42 in order to maintain a proper pressure between the tape backing 34 and the drive roller 40. A suitable drive motor 43 is mounted on the side frame 21 for driving the drive roller 40. An overrunning clutch (not shown) may be fitted between the drive roller 40 and the motor 43 to allow the tape to be unspooled at a rate faster than the motor drive speed in such manner that the machine travel rate determines the tape speed during the actual tape laying operation.

The backing web 34 is separated from the tape 33 on the underside of the drive roller 40 in the manner as illustrated in FIGS. 2 and 4 and the backing web 34 is then trained around an idler roller 44, the latter being secured to a shaft 45 joumaled on the side frame 21. As indicated previously, in many cases it is not necessary to separate the tape from the backing web, in which case the idler roller 44 would not be employed.

The tape 33 which has been separated from the backing web 34 is then passed along a guide plate 46 and into tape cutting mechanism 47 and a heating mechanism 48 in the manner as illustrated in FIGS. 2 and 4. The tape cutting mechanism 47 and the heating mechanism 48 will be hereinafter described in more detail.

Finally, the tape 33 is again brought into facewise engagement with the backing web 34 along the annular surface of a tape placement roller or so-called applicator roller 49, the latter being joumaled on a transversely extending roller shaft 50 and which is, in turn, secured to the extending arms 20, The tape placement roller 49 is pneumatically inflated to provide an adjustable and variable pressure area. Secured to the side frame 21 and being connected to the extending arm 20 is an adjustable spring loading device 51 enabling an operator to adjust a roll-down pressure on the roller 49. This mechanism provides for a type of spring suspension of the tape placement roller 49 to enable compliance with variations in a complex surface. The spring loading device 51 is more fully illustrated in FIG. 7 and is described in more detail hereinafter. It should be observed that the impregnated tape 33 does not contact any portion of the tape placement roller 49 since the backing web 34 is interposed between the tape 33 and the roller 49. Furthermore, it can be observed that as the tape head T travels in the direction of movement of the arrow, reference being made to FIG. 4, the tape will be applied to the work surface W.

The backing web 34 is trained around a take-up spool 52 which is mounted on a powered spool shaft 53, the latter being joumaled on the side frame 21. The spool shaft 53 is driven by means of a high-slip motor 54 which provides a constant tension on the backing web 34 and with varying speed. It should be observed that the take-up spool 52 is retained on the shaft 53 by means of a locking nut 55 for convenient removal of the spool 52.

By reference to FIGS. 2 and 4, it can be seen that a guide shoe 56 clamps the tape 33 along with the backing web 34 to the tape placement roller 49 prior to retraction of the entire tape laying head T. With this mechanism, it is possible to maintain the tape position during the turn around" phase of the tape placement operation. It can be seen that the guide shoe assembly 56 is provided with an accurately shaped shoe surface 57 conforming to the surface of the tape placement roller 49. Furthermore, the guide shoe assembly 56 is pneumatically operable by means of a pneumatic cylinder 58.

By reference to FIG. 1, it can be seen that the tape laying head T travels with the carriage 2 along the axis X during the application of the tape 33 to the work piece W. As the tape is applied to the surface of the work piece W, it is severed in such manner that the terminal end of the severed section is coincident with the transverse margin of the work piece W. At this point, the gantry l is programmed to stop its shifting movement and the tape heat T will rotate for a 180 are so that another strand of tape can be laid adjacent to the previously deposited strand of tape on the work piece W. Furthermore, the carriage 2 will be shifted transversely in order to properly locate the applicator roller 49 with respect to the work piece W.

The tape head T includes an edge-alignment sensory assembly 59 which, in part controls the movement of the tape head T. This edge-alignment sensory assembly is capable of detecting the terminal edge of the work piece W in advance of that edge during the movement of the entire tape head T. Thus, the tape head T will stop its advancing movement at a prescribed location, and is signaled to stop its advancing movement in advance of the prescribed location. In addition, the edgealignment sensory assembly controls the cutting mechanism 47 so that the edge of the tape 33 is severed with an edge trim conforming to a peripheral edge of the work piece W.

The edge-alignment'sensory assembly includes a deceleration photocell 60 which is secured to a pivotally mounted bracket 61 in the manner as illustrated in FIGS. 2 and 4. In actual operation, a retro-reflective tape (not shown) is deposited on the edge of the work piece W, or preferably spaced from the edge of the work piece W, and is capable of being sensed by the photocell 60. The retro-reflective tape will have a substantially different surface emissivity than the work piece W so that the photocell 60 will be capable of detecting a marked change in surface emissivity as being the difference between the dark impregnated tape and a white strip of relfective tape. Thus, when the photocell 60 is actuated by its light beam reflected from the retro-reflective tape, it signals the tape head T and the controlling mechanism (not shown) for the gantry machine G to reduce the speed of movement of the carriage. This reduction in speed insures that the edgealignment sensory assembly will have sufficient time to rotate into position accurately, in a manner to be more fully described in detail hereinafter.

The edge-alignment sensory assembly 59 also includes a pair of photocells 62, 62' mounted on a linkage mechanism 63 which swings the photocells 62, 62' through a i45 arc with respect to the centerline of the tape being deposited. The linkage mechanism 63 and the photocells 62, 62 are more fully illustrated in FIG. 6. The link mechanism is biased rearwardly, reference being made to FIG. 6, by means of a compression spring 64 which bears against a flat plate 65. The plate 65 is connected to the link mechanism 63 by means of a pair of spaced rods 66 which extend through axial bearings 67. Furthermore, an adjustment screw 68 is provided for regulating the degree of bias rearwardly on the linkage mechanism 63.

It can be seen that the photocells 62, 62' are mounted on a flat cross bar 69 which is secured to a mounting plate 70, the latter in turn being secured to a pair of shiftable links 71, 72. Finally, the mounting plate 66 is shifted by means of a bar 73 connected to the rods 66. By further reference to FIG. 6, it can be seen that the links 71, 72 are secured to stepping links 74, 75, respectively, which are in turn shifted through an anchor 76 on a vertical drive shaft 77. The drive shaft 77 is in turn driven through a gear mechanism 78 by means of a stepping motor 79, the latter being illustrated in FIGS. 2 and 5. The link structure 63 with the attendant links 71, 72 and the drive link 73 all form a stirrup structure so that the photocells 62, 62' essentially ride on an idle cross bar. In this manner, they are free to rotate i 45 parallel to the work surface.

When either of the photocells 62, 62 detects a marked change in surface emissivity as being the difference between the dark pre-impregnated boron (or graphite) tape and a white skirt or strip of reflective tape on the work piece W, the photocells will, in essence, hold to the colored change line. This allows the other of the photocells to swing forward. Thus, if the photocell 62 first detected the colored change line, represented by the demarcation between tape and the work piece W,-the other photocell 62 would swing forward through the action of the stepping motor 73. Thus, as the tape head T continually moves forward, the photocell 62 will continually shift causing the link mechansim 63 to rotate the photocells 62, 62' until both photocells are in complete alignment with the edge of the tape 33.

By further reference to FIG. 4, it can be seen that the photocell 60 is located so that it detects the position of a point during the movement of the tape head T toward that point and prior to the time that the tape head T reaches that particular point. Thus, in the case of the present invention, the photocell 60 will be the first of the photocells to detect the presence of the retroreflective tape. In normal practice, it is desirable to place the tape approximately 2 inches from and in parallel relationship to the edge of the work surface. These relationships are more fully illustrated in FIGS. 10 and 11. Thus, if the tape placement h'ead were moving in a path such as that designated as Y, in FIG. 10, the tape placement head T would be moving toward the work piece edge designated as Z,. The photocell 60 would detect the retro-reflective tape Z which is fixed approximately 2 inches from the edge of the work surface Z As the photocell 60 detects the retro-reflective tape Z a signal is generated to slow-down the movement of the tape head T. Furthermore, it can be seen thatsince the tape head T is moving in a direction completely perpendicular to the edge of the work surface Z and the retro-reflective tape Z that the photocells 60, 62 will not change their relative position. Accordingly, when the two photocells 60, 62' contact the retroreflective tape Z a signal will be generated to initiate the tape cutting mechanism 47. At this point the tape 33 will be severed. 7

It is to be noted that these time-distance relationships are fixed, but yet are adjustable in the tape head T. For example, when the applicator roller 29 is located at the position illustrated in FIG. 11 and a cutting signal is generated, the tape 33 will be severed. The distance between the severed edge of the tape 33 and the point of contact of the applicator roller 49 (designated as S) is equal to the distance between the this point of contact S of the roller 49 and the work piece edge Z, (distance designated as X,). Furthennore, it is to be noted that the cutting signal is generated when the photocells 62 and 62 are aligned with work piece edge and both detect the line Z as illustrated in FIGS. 10 and 11.

I It can be seen that if the tape placement head T was moving along the path Y as illustrated in FIG. 10, then a somewhat different time relationship is created. When the tape placement head T is moving in the path Y the photocell '60 will detect the retro-reflective tape Z generating a signal to slow-down the movement of the tape head. However, since the tape placement head T is moving in an angulated path the distance between Z, and Z in the direction Y is not equal to the distance between Z and Z in the direction Y,. The tape placement head T of the present invention compensates for this change of distance. Thus, the two photocells 62 and 62 will not contact the retro-reflective tape Z at the same point in time. The first photocell 62' will contact the retro-reflective tape Z This will cause the other of the photocells 62 to shift around through the action of the link mechanism 63 as illustrated in FIG. 6. However, it is to be noted that the link mechanism 63 actually extends forwardly in order to compensate for the additional distance between Z and Z as a result of the tape head moving in the path Y Accordingly, when the photocell 62' detects the retro-reflective tape 2;, the link-71 will remain stationary but photocell 62 will shift forwardly through the action of the link 72. It is to be noted that the link 72 is movable through the stepping link 74 by the action of the anchor 76. The actual point of rotation will occur about the point of connection between the link 71 and the mounting plate 70. Furthermore, it can be observed that the entire linkage mechanism 63 shifts forward. The drive link 73 actually shifts forwardly through the action of the rod 66 moving through the axial bearings 67. Furthermore, this forwardly moving action occurs against the action of the compression spring 64. Thus, it can be seen that the photocells 62, 62' not only compensate for the angle between the direction of movement of the tape head T and the edge of the work surface, but actually compensate for a variance in distance between the edge of the work surface Z and the retroreflective tape Z caused by the angle of movement of the tape head T. It can also be observed at the end of the work cycle, that the two photocells 62, 62 will be shifted back to their normal positions, as illustrated in FIG. 6, and, furthermore, the entire assembly will be shifted to the right by the action of the compression spring 64.

In addition, it can be seen that as a result of the tape head T movement in the path Y an additional distance of X is generated in FIG. 11. Accordingly, when the two photocells 62, 62' shift in order to match the edge of the work surface 2,, they will be extended for a distance X The tape cutting mechanism 47 is more fully illustrated in FIG. 5 and generally comprises a frame 84 which is rotated through a i 45 are by means of the stepping motor 79. It can be seen that the frame 84 is secured to a shaft 85 supported by roller bearings 86 and is driven through a pair of pulleys 87 and a drive belt88. Thus, it can be seen that when the stepping motor shifts the photocells 62, 62 to become aligned with the retro-reflective tape, the stepping motor 79 will also shift the shear frame 84. Rigidly secured to one end of the shear frame is a blade 89 and which is engagable with a similar blade 90, the latter being secured to a slideable plate 91. By further reference to FIG. 5, it can be seen that the plate 91 is shiftable along a pair of guides 92 forming part of the frame 84 and is powered by means of a pair of pneumatic cylinders 93, the latter being secured to the frame 84. Thus, it can be seen that the cutting blades 89, are pneumatically operated by the paired cylinders 93. Furthermore, this mechanism is capable of cutting a three-inch wide tape through an arc of :2: 45 with respect to the tape centerline. The blade 89 actually serves as a type of anvil and is preferably formed of teflon. The blade 90 which is shiftable with respect to blade 89 serves as a crushing type of blade.

Thus, the edge-alignment sensory assembly also drives the tape cutting mechanism 47. As one of the photocells 62, 62 pick up the reflections of its integral light source from the retro-reflective tape, the motor 79 is actuated to operate in a direction corresponding to the cells position. As the shear frame 84 rotates, it also drives the link structure 63 to the angle of the retro-reflective tape. When the second photocell is activated, the stepping motor 79 stops the rotation of the shear frame 84 and also thereafter energizes a solenoid valve (not shown) which controls the cylinders 93 to cause the tapeto be severed.

By further reference to FIG. 7, it can be seen that the spring loading device 51 is designed to provide an adjustable spring loading pressure on the applicator roller 49. The spring loading device 51 essentially cooperates with the side frame 21 and the arm in the manner as illustrated. The spring loading device 51 generally comprises a bracket 94 which is welded or otherwise secured to side frame 21 in the manner as illustrated. In addition, the bracket 94 has a flange 95 which extends through a slot 96 formed within the arm 201. Furthermore, the bracket 94 has a lower flange 97 which also extends outwardly from the side frame 21 and the flanges 95, 97 carry adjusting screws 98, 99, respectively. Both of the adjusting screws are capable of bearing against a spring bias 100 which is biased downwardly through the action of the spring 101. Thus, it can be seen that the applicator roller 49 is carried by the arms 20, 20 and partially held by the side frame 21. However, the roller 49 is shiftable to a slight degree with respect to the side frame 21 so that it is capable of compensating for variance in the work surface W. The degree of bias tension maintained on the roller 49 is adjusted by the upper screw 98 with a possible degree of lowermost movement of the applicator roller 49 regulated by means of the screw 99. The desired load pressure maintained on the applicator roller 49 is determined by the many factors which affect the tape laydown characteristics. For example, a soft, resin-rich tape would require less roller load for a good adherence than would be required for a dryer tape.

The heating mechanism 48 is more fully illustrated in FIG. 8 of the drawings and generally comprises a quartz lamp 104 which is located within a frame 105. The frame 105 is rotatably mounted on a shaft 106 and operates a pair of microswitches 107, 108 by means of a cam 109 located on an extension of the shaft 106. In like manner, the extension of the shaft 106 is secured through a coupling 110 to an electric motor 111. The frame 105 is located so that the quartz lamp 104 provides an infrared type of heat source and the frame 105 concentrates the heat in a 0.06 to 0.09 inch wide band at the focal point of the reflector. The quantity of heat is controlled by a console mounted transformer or rheostat (not shown). At any point in time when the tape 33 stops moving in the tape head T, the electric motor 111 is energized to rotate through shaft 106 the frame 105 and, hence, the quartz lamp 104 away from the tape 33 to prevent localized heating of the tape and thereby avoiding a premature cure of the tape.
