(01. Hi l--42) 16 Claims. 1.

This invention relates to machines for serving adhesive tape and is particularly adapted for the serving of pressure sensitive or normally tacky adhesive tape.

Machines have heretofore been devised for serving comparatively short lengths of, light or narrow pressure sensitive adhesive tape but for certain purposes it is desired to serve long lengths of pressure sensitive tape and particularly long lengths of comparatively wide and heavy tape. Such long lengths of tape are used for many purposes, such as sealing large packing cartons.

Much of this tape is usedby the Army and Navy for the sealing of food shipments for overseas service. The handling of such large and. wide pieces of tape presentsmany problems not met with in the handling of small short pieces oftape and existing machines are unadapted for the purpose.

It is an object of the present invention to provide a compact and efficient machine for serving measured lengths of adhesive tape and particularly comparatively long lengths of pressure sensitive adhesive tape.

It is another object of the inventionto provide a machine of this character in which a. crank. or hand or foot operated member or power mechanism is used to draw the tape from the roll of tape and measure the desired length to be used, the measured length of tape being then pulled from the machine by hand and out 01f. By using a part of the mechanism to do the actual pulling of the tape from. the roll of tape, an operation which requires considerable force in the case of comparatively wide rolls of. pressure sensitive tape, the unwinding and withdrawing of the tape from the roll is done by the machine andthe tape may thereafter be pulled out of the machine by slight pressure of the hand. Furthermore, by using the mechanical parts of the machine to pull the tape from the, roll these mechanical parts may also be used toeffectively measure the length of tape pulled off the roll. and prepare it for manual removal. In this way accurately measured lengths are served and wastage of, the tape is avoided, This is important when using wide and heavy pressure sensitive tape as such tapes are frequently laminated from one or more layers and sometimes even have cloth backing and are comparatively expensive so that wastage becomes a substantial factor of cost.

Another object of the invention is to provide adjustable stopping means for assisting in the delivery of preselected lengths of tape, these stopping means being preferably arranged so that one or more difierent predetermined lengths of tape may be dispensed, as desired.

Another object of the invention islto provide visual means for measuring the length of tape to be. served.

In accordance with the present invention the tapeserving machine ispreferably provided with mechanism for drawing a. length of the adhesive tape, preferably inthe. form, of a loop, from; the roll of tape, which length or loop is held in a. more or less taut. condition within the machine prior to being manually withdrawn when it is to be used. The power: of the machine may thus be used to overcomethe resistance caused. by the tight winding of the adhesive tape on the tape roll and the only, force necessary to: apply when withdrawing the tape from the machine is that required to withdraw the loop previously formed in the machine. Furthermore by withdrawing the tape from the roll in loop form approximately twice the length of tape may be pulled from; the roll and formed into the loop as. the distance which it is necessary for the; loop forming: means toimove. Thus long lengthsof tape maybewithdrawn and served from a comparatively compact machine; It the tape. were merely drawn out in a straight. line from the roll obviously the overall dimensionsv of, the machine would be: much greater. The machine can also be operated; in such a way as to provide a timed withdrawal. of the tape from the closely wound roll- It is ordinarily not practicableto jerk or pull the tapevery quickly from the roll because of its close adhesion to the underlying layers thereof. Asthe machine does this part of the withdrawing it is easier to control the rate at which the unwinding is carried out. The tape having been formed into the; loop within the machinemay thereafter be drawn. out by hand as rapidly as desired because there is no particular resistance to be overcome.

In the machine illustrated the loop is formed by a movable feed roller engaging an intermediate portion of the tape between the supply roll of: tape which acts as an. anchor at one end of the loop: and an anchoring means at the delivery end of the loop; such, anchoring means preferably being in the form of a ratchet roller to which the end of the tape is adhered. Such roller will permit the tape in the loop to be withdrawn freely from the machine but will prevent the end of the tape frombeing pulled back into the machine. Such ratchet roller thereby forms an anchor for the free end of the. tape. By moving the feed roller, against the tape, which is thus anchored at both ends, tension is put on the tape and as "over which the roll of tape is forced.

the ratchet roller cannot turn backward, this anchorage for the free end of the tape will not yield and the pull on the tape results in drawing the tape from the supply roll. Thus the loop is enlarged until the desired length of tape is withdrawn from the supply roll. There are thus three elements involved in the forming of the loop, namely the anchoring ratchet roll or other anchoring means at the free end of the tape, the supply roll to which the tape adheres and from which it must, be pulled, and the intermediate feed or loop forming roll. In the embodiment of the invention illustrated in this case the loop is formed by moving the feed roll but obviously the tape might be withdrawn from the supply roll by moving either the anchoring ratchet roll, the feed roll, or the tape supply roll, or by moving any two or three of these elements relatively to one another. The important consideration is to provide means in the machine for forcibly withdrawing the tape from the supply roll and holding it suspended in such manner that it may be manually withdrawn from the machine with a light pull when required.

In the accompanying drawings, in which I have illustrated one preferred embodiment of my invention,

Figure 1 is a longitudinal vertical section of the machine taken on the line l-l of Fig. 2, with certain portions in side elevation.

Figure 2 is a front View of the machine with parts of the cover plate broken away so as to show the internal construction;

Figure 3 is a transverse vertical section of the machine taken on the line IIIIII of Fig. -l and Figure 4 is a fragmentary view in horizontal section with the operating handle in its forward position.

Referring to the drawings in detail, the machine has a frame which is shown as comprising formed as a wooden roller having grooves therein in which are fitted bowed flat springs 28 In the construction shown the roll of tape is wound adhesive side in and the tape is led from the roll as a strip 32 passing first over the guide roller 3 3. As the tape is wound adhesive side in, in the example shown, it will be seen that the adhesive side of the tape passes over the guide roller In order to prevent the tape from adhering too firmly to such guide roller the surface of the latter may be treated by being sanded or in any other suitable manner which will prevent too close adherence. The tape passes from the guide roller 34 over a feed roller or pulling roller d}, then over a guide roller 32 and finally under an anchoring roller or ratchet roller 36. In the construction shown the non-adhesive side of the tape passes over the rollers Li!) and 52 while the adhesive side of the tape is in contact with the ratchet roller 44. The ratchet roller t rotates about the axis of a spindle 46 and is provided at one end with a ratchet wheel 38 which is engaged by a pawl 58 pressed in contact with the ratchet wheel by a spring 52. This arrangement permits the roller 45 to rotate in a clockwise direction (Fig. 1) thereby permitting the tape to be freely pulled out of the machine. The ratchet roller, however, will not rotate in the other direction so that the tape is firmly held against being pulled in the opposite direction owing to the adhesion of the tape to the roller.

In the form of the invention shown tape is withdrawn from the supply roll by movement of the feed or puller roll 40. The latter is mounted between the arms of feed yoke 65 the other ends of the arms being fixed to a shaft 62 journaled in the side walls l2 and i i and having keyed thereon a gear 64. The gear 5:3 meshes with a gear 86 keyed to a shaft 68 the outer end of which is fixed to a crank it having an operating handle 52. Movement of the operating crank in a counterclockwise direction (Fig. 1) will result in swinging the arms of the yoke Si! in a clockwise direction from the position shown in full lines in Fig. 1 to the position shown in dotted lines in said figure (or to some intermediate position depending upon the length of strip to be fed). Obvious- 1y any suitable means for moving the puller roll be substituted for the particular mechanism illustrated. The pulling force can be applied by means of a hand crank, as shown, or by power or otherwise as desired, and the various parts may be connected by gearing of any appropriate form. Movement of the yoke 60 in a clockwise direction as described, results in the formation of a taut loop of tape. As the tape is anchored to the ratchet roll M it must be drawn from the sup-' ply roll 22. Furthermore as the tape is withdrawn into a doubled loop, as indicated at 89, it will be seen that approximately twice the length of tape will be withdrawn as the length of the distance moved by the puller roll 40. This admits of a compact construction of the machine.

The leading end of the tape in front of the ratchet roller M rests adhesive side up on a support or table 8d. In this position it may be readily grasped by the operator, particularly as the adhesive side is exposed, so that it may be picked up by merely touching the fingers to the adhesive side. When the operator desires to use the tape he takes hold of this end resting on the table and pulls out the tape which is contained in the machine in the loop 89. The pulling out of this tape involves no great effort as it merely means the drawing of the tape over the guide rollers and the moving of the puller roller 4G and yoke and gear and crank, all of which parts move freely. It is not necessary to overcome the resistance to the stripping of the tape from the supply roll because this has already been done by the operation of the crank. The manual withdrawal of the tape from the loop in this manner returns the crank and associated parts to initial position ready for the next operation. Figure 1 shows the parts in such position in full lines, and shows the crank and yoke in dotted lines in the position at the end of the loop forming stroke at which time the tape is in condition for the operator to draw it manually from the machine.

As the crank is moved by the hand of the operator in counterclockwise direction (Fig. l), on its active stroke while it acts to form the loop and withdraw the tape from the tape supply roll and as it is returned to. its initial position by the act of manually withdrawing the tape from the machine, it is unnecessary to provide spring means for moving it in either direction. However it is desirable to provide a relatively light or holding spring which tends to: urge the crank. in. a. counterclockwise; direction. and. thus prevent it from being accidentally pushed irnthe opposite direction: before: the tape. is manually withdrawn from the machines The crank is thus urged. in a direction. inwhicha it will maintain the tape loo-ptaut thereby preventing the sides of the loop fromisa gging. Withl possible contact between. the sides of. the loop orbetweenportions oiithe. loop and some: part of the mechanism. This is important because: of. the. tacky nature of thetape: which immediately adheres to anything it touches; In the: construction shown a comparatively weak spring is provided. which is anchored at one end to afixed support 92 and at the. other end is woundpart way around a spool. 94 on the crank. shaft 68, this end being. anchored to a pin 96: fixed. in such. spool. Ifhis spring should not be strong enough to move the crank or actuate the yoke 68,. against the resistance necessary to unwind the: tape from the roll, so that the spring will not feed the. tape. Any other suitable means for preventing. accidental displacement of the crank may be utilized. In the construction of the machine. illustrated, the weight of the crank and its handle substantially balances the weight of the yoke 69 and roller 40, and as these partsmove in opposite directions they substantially balance each other in all positions.

Suitable means for severing the tape. are preferably provided. If the machine is used for dispensing a heavy strong tape such asheavy paper backed or cloth backed tape it is desirable to provide a positive shear cutter means. If. the machine is used for dispensing light tape, such. as cellophane tape, a simple. serrated cutter or tear off blade may be used. In. the construction shown a shear cutter is illustrated this comprising a ledger blade Illi! fixed to the plate 3t and with which cooperates a pivoted shear blade IE2. one end of which is pivoted on a post Iil l fixed in a pivot block I'ilfi- A. spring Ifiiiis preferably provided to hold the shear blade inv retracted position and the shear blade is. provided with a. pad or handle II!) by which it may be manually actuated. The shear. blade is located far enough in front of. the ratchet roller i to leave an end of the tape long. enough to be readily grasped. Obviously, if desired. an automatic shear blade might be employed, arranged to be actuated in, accordance with the movements of the operating crank. Such constructions are well known and need. not therefore be described in detail. The use of a pivoted shear blade engaging the upper tacky surface of the tape has the advantage that after the tape has been sheared the rear end of the cut off portion tends to adhere lightly to the. cut.- ting edge of the shear blade so that as the blade goes up it lifts up this end. of the tape and prevents it from dropping to the benchor floor. Instead itwill remain momentarily affixed. to the blade until the operator is ready to take hold of it when transferring the cutoff strip of tape to the carton or other article to be sealed- Suitable means are preferably provided for measuring the amount of tape withdrawn from the tape supply roll, and therefore for measuring the length of the piece of tape which the operator can. withdraw from the machine for application to the carton. In the construction shown a visible indicating scale for making such measurements is provided and adjustable stops are also provided. The visual scale consists of a calibrated scale plate or strip: I201 which. is mounted. on a. measuring. drum I122: attached to the: side of the machine... The measuring. drum is mounted concentrically of. the crankshaft: 68 and the crank I0 has apointer I26. which. moves over the scale and enables. the operator to read at once the length of. tape'measured; out. for any particular position of. the crank. If the: opera, tor wants to withdraw a piece of tape say 30 inches long, he draws the handler forward until the. pointer I26 is opposite". the. numeral. 30. on the: scale I 21]. This. position of the crank corresponds with the given position. of the feed yoke in: which a. loop; hasibeen formedi oi such length as; to permit a 3.0. inch piece of tape to: be pulled outof the machine-and cut off;

In some cases it is. desirable to provide an: ad;- justablei stop or stops. which may be. used". for the movement. of the crank where one or more. predetermined lengths of. tape are; to: be fed repeatedly. For. example; the. measuring drum. I22- is showni as providedawith an. arc-shaped slot I36 in. whichslides a bolt [3.2 having. ahead I34 and adapted to; be. clamped in desired 1105i?- tion; in; the: slot by means of a. clamping. nut. 1.3m The head I34. constitutes a stop adapted: to be engaged by a projection: I40 carried; on. a: length selector slide I 44. mounted. to have. a: limitedilonr gitudinal sliding movement on the: crank. The stop I34 is of sufficient. size to be. engaged by; the projection I40 irrespective of the particular ad;- iustment of. the selector slide so that the movement of the crank is always: limited: by the position of this stop which may be termed the final feed stop. Where it is desiredto feed alternately or at intervals one or more-shorter lengths of tape than the length for which the stop I34 is set. an optional feed stop is provided which coinprises a lug I48: formingpart of. the head I50 of. a bolt L52 mounted. in the slot I36. and. adapted to be adiustably clamped therein by the nut I56. When the length. selector slide M4 is. moved. outwardly then the projection I40: will: clear. the: optional. feed stop M8 and: permit a length of tape to be measured. determined by the setting or the final feed stop I34. When the length: selector slide is pushed inwardly, however,.W-hich; may be done by the thumb of the operators hand holding. the: crank. handle. 12 being engaged with. a finger piece I60 on the end of the length selector slide, then the projection I40 will contact with the optional feed stop I48 and thereby limit the movement of the. crank so as to measure, out a shorter length of tape. In. this way the operator may measure either one. or two lengths of tape as often as desired without changing the positions of either of the feed stops.

While I have illustrated and described in. detail certain preferred forms of my invention, it is to be understood that changes may be made therein and the invention embodied. in. other structures. I. do not, therefore, desire tolimit myself. to the specific constructions illustrated, but intend to cover my invention. broadly in Whatever form its principle may be embodied.
