- This invention relates to a marking or printing machine designed for making a series of similar imprints in spaced relation on the non-adhesive face of pressure sensitive adhesive tape, an example of which tape is that commonly known to the trade as Scotch tape.
- Pressure sensitive adhesive tape which is thus imprinted is frequently used for making pressure sensitive adhesive labels, this being done by cutting the printed tape transversely between the successive imprints to produce the desired labels.
- a pressure sensitive adhesive label has the advantage over a gummed label that it can be applied to any article simply by pressing it against the article and without the necessit of activating the adhesive material. Furthermore the adhesion between a pressure sensitive adhesive label and the article to which it is applied is more permanent than that of a gummed label, because the pressure sensitive adhesive label is not affected by moisture or heat.
- One of-the objects of the invention is to provide a machine which will unwind a roll of pressure sensitive adhesive tape to be printed, make a succession of imprints in spaced-apart relation on the non-adhesive face of said tape, and then rewind the printed tape in roll form; all as a continuous operation.
- a further object of the invention is to provide a machine of this type with novel means by which the successive imprints on the tape can be placed at varying distances apart, thereby providing for making labels of different lengths.
- Still another object of the invention is to provide a machine of this type which is simple in construction and inexpensive to manufacture and easy to operate.

- the printing head 9 is shown as secured to a reciprocating carriage H which is supported by and reciprocates on a supporting-stationary shaft [2 carried by the upperportion of the housing section 2, said carriage ll having two apertured ears or bosses [3 through which the stationary shaft l2 extends.
- the carriage H is movable on its support l2 from its rearward position shown in Fig. 1 to the forward position shown in Fig. 2.
- the face of the type ill will come into tangential contact with the non-adhesive face of the portion of the tape 1 which rests on the impression cylinder 8, and during such forward movement of the printing head, the freely rotatable impression cylinder is given a rotative movement by which the tape is fed forward and hence as the printing head passes across the upper face of the impression cylinder, the desired printed impression will be made upon the tape.
- the impression cylinder 8 is mounted for slight vertical movement between its raised operative position shown in Fig. 1 and its lowered inoperative position shown in Fig. 2. Said cylinder is held in its raised position during the forward movement of the printing head by which the imprint is made on the tape, and when the printing head reaches the limit of its forward movement, the impression cylinder 8 is lowered slightly so that during the backward movement of the printing head, the impression cylinder and the tape will be separated from the tape.

- the impression cylinder '8 is mounted for free rotation on a stud 80 carried by and projecting laterally from a horizontally extending rocking supporting member '23 which is pivoted at one end to the housing section 2 as shown at 24. Said'impression cylinder is mounted on the other end of the rocking member and as stated above is freely rotatable on its supporting stud '80. With this construction a swinging movement of the horizontally extending supporting member about itsjpivot'2fi will produce 2. raising and falling motion of the impression cylinder 8.
- Such up and down movement of the supporting member 23 is controlled by a cam member 25 on the drive shaft H3.
- the rocking member 23 has a downwardly extending portion 9t carrying a follower, herein shown'as a roll 26, which projects slightly beyond the vertical face 91 of said downwardly projecting portion and which is engaged by the cam member 25.

- the printing head has means associated therewith for turning the impression cylinder 8 at a surface speed corresponding to the speed of translation of the printing head during the time that the type is in contact with the tape. This is accomplished by a feeding shoe 29 which is mounted on the printing head and which has frictional engagement with the impression cylinder during the forward movement of said printing head, such frictional engagement serving to rotate the impression cylinder with a surface speed equal to the speed of translation of the type and thereby feed the tape I forward, said tape being drawn oil from the roll 6 during its forward movement.

3 Claims.
This invention relates to a marking or printing machine designed for making a series of similar imprints in spaced relation on the non-adhesive face of pressure sensitive adhesive tape, an example of which tape is that commonly known to the trade as Scotch tape.
Pressure sensitive adhesive tape which is thus imprinted is frequently used for making pressure sensitive adhesive labels, this being done by cutting the printed tape transversely between the successive imprints to produce the desired labels.
A pressure sensitive adhesive label has the advantage over a gummed label that it can be applied to any article simply by pressing it against the article and without the necessit of activating the adhesive material. Furthermore the adhesion between a pressure sensitive adhesive label and the article to which it is applied is more permanent than that of a gummed label, because the pressure sensitive adhesive label is not affected by moisture or heat.
One of-the objects of the invention is to provide a machine which will unwind a roll of pressure sensitive adhesive tape to be printed, make a succession of imprints in spaced-apart relation on the non-adhesive face of said tape, and then rewind the printed tape in roll form; all as a continuous operation.
A further object of the invention is to provide a machine of this type with novel means by which the successive imprints on the tape can be placed at varying distances apart, thereby providing for making labels of different lengths.
Still another object of the invention is to provide a machine of this type which is simple in construction and inexpensive to manufacture and easy to operate.

Fig. 11 is a view of a pressure sensitive adhesive tape on which imprints have been made by the machine and from which separate labels can be formed.
Fig. 12 shows a section of a laminated or twoply tape from which a two-color label can be made.
Fig. 13 is a view illustrating another laminated three-ply tape from which a three-color label can be made.
In the machine herein shown the operative parts thereof are enclosed in a suitable housing I which is formed with the rear portion 2 on which the operative parts of the machine are supported, and a front portion 3 which is hinged to the rear portion 2 as shown at 4 in Figs. 1 and 2 and which constitutes a door which can be opened to give access to the operative parts.
The rear section 2 of the casing or housing is provided with means, such for instance as a laterally extending pin 5, on which may be mounted a roll 6 of the pressure sensitive adhesive'tape 1 that is to be printed.
The printing couple by which the imprints are made on the non-adhesive face of the tape comprise a freely rotatable impression cylinder 8 over which the tape 1 passes with its adhesive face in contact with the cylinder, andaprinting head 9 carrying type It which is mounted for reciprocating movement. The printing head 9 is shown as secured to a reciprocating carriage H which is supported by and reciprocates on a supporting-stationary shaft [2 carried by the upperportion of the housing section 2, said carriage ll having two apertured ears or bosses [3 through which the stationary shaft l2 extends.
The carriage H is movable on its support l2 from its rearward position shown in Fig. 1 to the forward position shown in Fig. 2. During the forward movement of the carriage, the face of the type ill will come into tangential contact with the non-adhesive face of the portion of the tape 1 which rests on the impression cylinder 8, and during such forward movement of the printing head, the freely rotatable impression cylinder is given a rotative movement by which the tape is fed forward and hence as the printing head passes across the upper face of the impression cylinder, the desired printed impression will be made upon the tape.
The impression cylinder 8 is mounted for slight vertical movement between its raised operative position shown in Fig. 1 and its lowered inoperative position shown in Fig. 2. Said cylinder is held in its raised position during the forward movement of the printing head by which the imprint is made on the tape, and when the printing head reaches the limit of its forward movement, the impression cylinder 8 is lowered slightly so that during the backward movement of the printing head, the impression cylinder and the tape will be separated from the tape.
The carriage l i is given its reciprocating movement through the medium of a lever M, the upper 'end of which is pivoted to the carriage at l5 and the lower end or" which is provided with a slot [6 that embraces a pin I! extending from the casing section 1. The lever I4 is given an oscillating movement about the pin I! as a fulcrum by means of a drive shaft H! which is journa'led in the housing section 2 and is provided with a' crank it having a crank pin 28 on which is mounted a block 2! that is received between two cheek pieces '22 with which the lever 14 is provided. With this construction the rotation of the shaft 18- and crank l9 will operate to oscillate the lever 14 about the pin ll as a fulcrum thereby giving the carriage H its reciprocating movement.
The impression cylinder '8 is mounted for free rotation on a stud 80 carried by and projecting laterally from a horizontally extending rocking supporting member '23 which is pivoted at one end to the housing section 2 as shown at 24. Said'impression cylinder is mounted on the other end of the rocking member and as stated above is freely rotatable on its supporting stud '80. With this construction a swinging movement of the horizontally extending supporting member about itsjpivot'2fi will produce 2. raising and falling motion of the impression cylinder 8.
Such up and down movement of the supporting member 23 is controlled by a cam member 25 on the drive shaft H3. The rocking member 23 has a downwardly extending portion 9t carrying a follower, herein shown'as a roll 26, which projects slightly beyond the vertical face 91 of said downwardly projecting portion and which is engaged by the cam member 25. This cam is provided with a high portion 2'! and a low portion 28 and is so constructed that when the crank I9 is passing its rear dead center as shown inFig. 1, the high portion of the cam will come intoengagement with the roll 26 thereby swinging the support 23 upwardly about its pivot 24 and placing the impression cylinder 8 in its raised operative position shown in Fig. 1 in which position the plane of movement of the face of the type 9 will be tangential to the impression cylinder.
. When the carriage H has reached its forward position shown in Fig. 2 and the imprint has been made on the tape '5 and just as the carriage II is ready to begin its rearward movement, the high portion 21 of the cam 25 will pass oil from the roll 26 thus allowing the support 23 to swing downwardly sufiiciently to carry the impression cylinder below and spaced from the plane of movement of the face of the type so that during the backward movement of the printing head, the type will be separated from the tape and the impression cylinder.
The printing head has means associated therewith for turning the impression cylinder 8 at a surface speed corresponding to the speed of translation of the printing head during the time that the type is in contact with the tape. This is accomplished by a feeding shoe 29 which is mounted on the printing head and which has frictional engagement with the impression cylinder during the forward movement of said printing head, such frictional engagement serving to rotate the impression cylinder with a surface speed equal to the speed of translation of the type and thereby feed the tape I forward, said tape being drawn oil from the roll 6 during its forward movement.
In the present invention the type characters iii are removably mounted in a type carrier element 30 which is removably mounted in the body portion 31 of the printing head. This body portion '31 has a channel shape and is provided in each side with a 'gui'deway 32 to receive the type carrier 30. Said type carrier is provided with one or more type-receiving openings 33 in which the type elements I0 may be placed. Each type element has a type character 34 formed on its printing face and is provided with an enlarged upper end 35 which presents downwardly facing shoulders 31 to engage the upper side of the type carrier '39 when the type elemerits are in position-as shown in Figs. 4 and 6. The enlarged upper end -35 of eachtype element has such dimension that when the type carrier 3:1 with the type therein .is introduced into the ways 32 of the printing head, the upper ends of the individual type will engage and be backed b the surface 81 of the body portion 3| of the printing head.
The type carrier is shown as provided with a thumb piece or knob 36 by which it can be withdrawn from the holder 31, and when so Withdrawn the type elements can be reset in the type carrier 3!! to provide for making any desired imprint.
The feeding shoe 2&3 by which theimpression cylinder 8 is given its feeding movement is shown as detachably mounted on the type carrier 30 at its rear end by means of screws '91. The holder 3| is provided at its rear end with a depending stop flange 38 with which the type carrier 38 has engagement when the latter is properly inserted in the holder 3 I.
The extent of the feeding movement which is given to the impression cylinder 8 during the forward movement of the carriage 'II is determined by the length of the feeding shoe 29, and by making this .shoe detachable from the carrier 30, it is possible to use feedingshoes of different lengths sov as to vary the spacing of the imprints on the tape 1.
For supplying the printing face 34 of they type elements 10 with ink, there is provided an ink rol1'39 which is mounted on the supportin member 23 and also ink distributing rolls Ml'and 4|. The roll 49 is rotatively mounted on a stud 40a stationarily carried by the housing sectionZ, but the roll 41 is carried by the supporting. member 23 and thus moves up and down with said supporting member. In addition there is provided an ink supply roll 52 which is mounted on' ashaft # 3 that is carried by the section. 2 of the housing frame and may be rotated by any suitable means; such for instance as a pawl and ratchet device (not shown) actuated from the lever I 4.
. winding roll 52 of printed tape.
The ink supply roll 42 receives ink from an ink reservoir 44. 1
When the supporting member 23 is in its lowered inoperative position shown in Fig. 2, the ink distributing roll 4| will be in its lowered position and in contact with the ink supply roll 42 and thus ink will be delivered from the roll 42 to the distributing roll 4|. When the carriage reaches the rear end of its movement as shown in Fig. 1 and the cam 25 becomes operative to raise the supporting member 23 into the position shown in Fig. 1, the ink distributing roll 4| is separated from the ink supply roll 42 and brought into contact with the distributing roll 40 so that ink is'transferred from the distributing roll 4| to the roll 40.
The carriage H has an ink pad 48 mounted thereon which is positioned so that during the forward and backward movement of the'carriage, said ink pad contacts with the roll 40. Hence at each forward and backward movement of the ink pad, it will receive ink from the roll 40, which in. turn has received ink from the roll 4|.
The ink roll 39, which is carried by the supporting member 23, is so positioned that when said supporting member is in its raised operative position, i. e., the position it occupies during the forward movement of the carriage said ink roll 39 is tangential to the plane of the face of the type In and also to the under face of the ink pad 48. Consequently during the forward movement of the printing head 9 and ink pad 48, the type will contact with the ink roll 39 and will thus be properly inked, and the ink pad 48 will pass across the ink distributing roll 40 and then pass over and in contact with the ink roll 39, by which operation said ink roll 39 will be freshly inked.
As stated above, during the backward movement of the carriage II, the supporting member 23 is in its lowered position shown in Fig. 2 so that the ink roll 39 will be below the path of movement of the type and the ink pad. During such backward movement, however, the ink pad will again move over and in contact with the ink distributing roll 49 and will thus receive additional ink.
During the backward movement of the carriage therefore, the ink distributing roll 4| is in contact with the ink supply roll 42 and is thus receiving a fresh quantity of ink, while during the forward movement of the carriage the freshly inked roll 4| is in contact with the ink distributing roll 40 and is thereby supplying the latter with ink. At the same time the ink pad 48 moves across the ink roll 4D and receives ink therefrom and the type I is carried across and contact with the ink roll 39 and is thus inked. During the final portion of the forward movement of the carriage I l, the ink pad 48 comes in contact with the ink roll 39 while it is still in its raised position and thus supplies said roll with additional ink.
The apparatus is also provided with means for rewinding the printed tape 1 in roll form, such rewinding operation being carried on simultaneously with the printing operation.
Mounted on the housing is an arm 49 carrying a shaft 50 on which may be mounted a core member which constitutes the core for the re- The shaft 5!] is driven from the driving shaft l3 by means of a non-positive driving connection which comprises a driving belt or sprocket chain 53 which passes around a pulley or sprocket wheel 54 on .movement of the carriage the shaft 50 and another pulley or sprocket wheel 55 on the drive shaft |8. The shaft 50 is shown as having a flange 56 rigid therewith and loosely mounted on the shaft is a companion flange 51 which is held in frictional engagement with the core 5| and rewind roll 52 by means of a spring 58. Means are provided for adjusting the tension of the spring, and for this purpose there is shown a washer 59 on the shaft 50 which is backed by a nut 60 screw threaded to the end of the shaft 50 so that by adjusting the nut 60, the spring pressure of the disk 51 against the roll 52 may be varied.
It will be understood that the forward feeding movement of the tape 1 which it derives from the impression cylinder 8 is an intermittent or step-by-step movement. At each forward rotative movement of the impression roll which occurs during the forward movement of the printing head, the tape I will be fed forward and withdrawn from the roll 6. During the backward II, the impression cylinder 8 is separated from the feed shoe 29 so that said cylinder and the tape 1 will remain stationary.
During the forward feeding movement of the tape, the wind-up roll 52 will be rotated to wind up the tape 1 thereon but during the backward movement of the carriage II and while the impression cylinder 8 is stationary, the wind-up roll will also be held stationary and slippage will occur between the wind-up roll and the disks 56, 51. The friction between the ends of the windup roll 52 and the disks or flanges 56, 51 may be so adjusted by means of the nut 60 that while it is sufiicient to rotate the roll 52 during the time that the tape 1 is fed forward, yet it will allow the slip-page to occur between the forward feeding movements of the tape.
For making adhesive lalbels, it is desirable that the pressure sensitive adhesive tape 1 should be opaque so that the imprint made thereon can be readily read. For some purposes it is desirable to use a two-color or even a three-color adhesive label. If a two-color label is desired, I propose to feed to the impression cylinder two pressure sensitive adhesive tapes 'of different color, one of which is wider than the other, and to laminate the tapes as they pass over the impression cylinder 8. This is illustrated in Figs. 10 and 12 wherein Ea represents a roll of wide pressure sensitive adhesive tape 1a of one color, and 6b is a roll of narrow pressure sensitive adhesive tape 1b of another color. The two tapes la and lb are fed to the impression cylinder 8 as shown in Fig. 10 and in such relation that the narrow tape 11) will be laid on top of the wider tape la. Because of the pressure sensitive adhesive nature of these tapes, they will become firmly united adhesively as they pass over the impression cylinder 8 thereby producing a two-color laminated tape as shown in Fig. 12. The type on the printing head may be so set as to make a printed impression on either the tape lb or the exposed portion of the tape la or on both tapes depending upon the character of the label it is desired to produce.
By mounting three rolls of pressure sensitive adhesive tape of three different colors on the machine, it would be possible to provide a threecolor laminated tape as shown in Fig. 13 which would comprise the narrow tape 1c of one color, another tape 1d wider than the tape 10, and of another color, and a third tape 76 wider than both the other tapes of still another color. By
7 laminating these tapes as shownin Fig. .13.:and then printing on the tape as above described, three-color printed labels may be produced.
The driving shaft ['8 may be rotated by any suitable means. In Fig. 3 there is shown .for this purpose a motor 89 which operates a shaft 88 through a reduction gear housed in a box 81, said shaft 88 having a gear 85 thereon which meshes with a gear 84 mounted on the shaft I8;
