My invention relates to improvements in machines for supplying adhesive strips of paper tape for use in fastening packages without the use of twine and may also be used for forming labels or the like, and the objects of my improvements are, first, to enable the paper tape to be printed in different colours as it is fed from the roll, and, second, to enable the strip to be fed positively and evenly.

I attain these objects by the mechanism illustrated in the accompanying drawings in which:

Fig. 1 is a side elevation of the machine,

A printing roller 1, which carries the type, is provided with two sets of inking rollers. Each set of inking rollers may be provided with an ink-feeding roller 8, ink-transferring rollers 9 and 10, and an ink-applying roller 2. The two sets of inking rollers are arranged in V-shaped formation in relation to the printing roller which is positioned at the bottom of the V. Each ink-applying roller 2 is made up of a rotatable spindle 11 on which felt inking discs 2A are slidably mounted and separated by distance pieces 2B. These discs are adapted to be fixed at any desired position along the spindle by selecting appropriate distance pieces, the discs and distance pieces being held in position by screw collars 2C. The discs thus supply ink of the desired colour to the corresponding portions of the printing roller, those positioned on one side of the printing roller supplying one colour and those positioned on the other side supplying a different colour. The screw collars act also as bearers to keep the felt inking discsv at typehigh distance from the printing roller. The rollers of each set of inking rollers are drawn together and into contact with the printing roller by a spring 12 on each side connected to the sliclable bearing of the outermost transfer roller 9 and at its other end connected to a lever 13 which is centrally pivoted to the framework and which at its other end is provided with a hook 14 adapted to engage a spindle 11 of the ink-applying roller. This draws the transfer rollers into close contact with the ink-applying roller and with each other and also presses the inkapplying roller into close contact with the printing roller. Two inking reservoirs 3 are positioned adjacent to the inking rollers. The paper 1A is drawn from a drum 1B having two cheek plates 1C carried on right and left hand threads of a spindle 1D having knurled heads 1E, by turning which the cheeks can thus. be adjusted to suit different widths of paper strips. The type or other matter to be printed may be cut or otherwise formed on rubber strips 5 adapted to be attached to the printing roller. The first feed roller 15 also functions as a supporting roller for the paper during printing, the spring-pressed printing roller pressing the paper against this supporting roller. This first feeding roller 15 carries a pinion 16 011 its end which is geared through an intermediate pinion 17 to a main operative pinion 18, and this intermediate pinion 17 is also geared to a pinion 19 on the end of a second feeding roller 20 which bears against an upper roller 21 which may have a pinion 22 on its end meshing with the pinion 19. The pinion 16 meshes with a pinion 23 on the end of the printing roller. The paper passes between the first feeding roller 15 and the printing roller 1, and also passes between the second feeding roller 20 and the roller 21, so that the paper is drawn out by an even pull. The rollers 20 and 21 are on fixed centre bearers. The main operative pinion 18 is in mesh with a second intermediate pinion 24; which is geared to a pinion 25 on the end of a second supporting roller 26. This roller supports the paper strip. The pinion 19 is geared through a pinion 27 to a pinion 28 on the end of the moistening roller 29. The moistening roller carries an endless belt 30 of felt or like material and. is held taut by a roller weight A so that the belt is partly immersed in water in a container 32 which is removable for filling purposes by unfastening front clips 32A. The belt is held on the roller 29 and roller weight 30A by collars 29A. An idle roller 31 rests on the moistening belt 30. The paper after passing between the rollers 20 and 21, is directed past cutting means and is then passed between the moistening roller and its idle roller. Consequently rotation of the operative pinion 18 causes the paper to be drawn forward by the two sets of feed rollers and also by the moistening roller after the paper has been gripped thereby so that delivery of the paper is effected by an exceedingly even pull and puckering up of the paper at any stage is practically impossible. hen a strip of paper is severed by the cutting means as hereinafter described it is still held momentarily by the moistening roller and its idle roller until it is ejected therefrom as those rollers rotate. The idle roller 31 is not geared to the roller 29 and its spindle 31A sits in U-shaped bearers 3113, so that the paper can be readily withdrawn owing to the roller 31 rising and turning freely.

The cutting mechanism comprises a spring-returned guillotine knife 33 (Figs. 1 and This guillotine knife is adapted to slide vertically in slides 34 under the action of alever 35 which is pivoted at 36 to the framework of the machine and is connected by a link 37 to a pin 38 on the end of a. lever 39. The lever 39 is pivoted at 40 to the framework of the machine so that when it is swung round as hereinafter described it pulls down the link 37 and the free end of the pivoted lever 35. The pivoted lever is connected to the guillotine knife by a pin 41 accommodated in a slot 42 provided on the lever. The lever 35 is provided with a return spring 43. As the free end of the lever 35 is drawn down the lever presses on the pin 41 and moves the guillotine knife downwards. On the return movement of the lever 35 under the action of the return spring 43 the guillotine knife is raised in a similar manner. The actuation of the lever 39 is as follows: The operative handle 44 of the device is mounted on a shaft 45 which carries a striker arm 46. On the downward movement of this striker arm the lever 39 is swung aside and the pin 33 on its outer end merely slides upwardly in. the loop 47 of the link 37. The operative handle is however provided with a return spring 48 and is held against movement in one direction by a pin 49 attached to the framework of the machine. Consequently when the handle 44 has been swung around as hereinbefore de scribed and is then released, its return spring 48 swings it immediately backwards, until it is stopped by a pin 50 attached to the framework of the machine. The striker arm 46 is simultaneously carried upwards and raises the inner end of the lever 39 thus swinging the pin 38 downwardly and drawing the link 37, lever 35 and guillotine knife 33 downwardly. The guillotine knife is provided with slanting edge as shown and cuts the paper against a fixed edge 51 which is adjustable by two set-screws 51A.

In order to allow the main operative pinion to feed the paper forwardly as above described and to allow the handle to swing backwardly without moving the paper, a ratchet wheel 52 is pinned to the shaft 45 and a series of spring-pressed pawls 53 is provided on the side of the main operative pinion 18 so that on the forward movement of the handle the ratchet is engaged by the pawls and drives the main operative pinion and its train of pinions, but on the backward movement of the handle the ratchet 52 is not engaged by the pawls and therefore moves freely leaving the operative pinion 18 stationary. The length of the stroke of the operating handle regulates the length of paper which is ejected and is controlled by the position of a stop 54 which is adapted to be fixed by a set-screw at any desired position in a slot 55 provided on the side plate of the machine. In order to enable the paper to be fed out continuously if desired, the stop 54 and pin 50 may be removed and the spring 48 may be freed from the pin 49 by providing the shaft 45 with a telescopic end 56 (Figs. 3 and 5) connected to the shaft by a pin 57 engaging a. slot 58. The telescopic end can be pressed in so that it carries the striker arm 46 and spring 48 out of alignment with the lever 39 and pin 49 respectively so that the handle is then free to rotate without operating the cutting mechanism.

The idle roller 31 above the moistening roller is formed as a series of thin discs 31C (Fig. 6) spaced about one-quarter of an inch apart from each other by distance pieces 31D, a sufficient number of discs being provided to ensure the paper strip being pressed firmly and evenly against the 1noistening roller. The object of this construction is that as the discs are thin the total area of the roller in contact with the paper strip is slight and consequently there is little danger of water collecting on the upper surface of the paper strip at the position where the roller contacts therewith. Preferably, the roller 21 is similarly constructed, but with about five discs only, to prevent the printed matter being smudged. Furthermore these discs on the roller 21 each leave a longitudinal impression line on the paper. It has been found that these impression lines maintain the paper straight and also facilitate its a-dhesiveness when moistened.

The machine is provided with a cover 59 and the spindles of the ink-applying rolle s and transferring rollers are slidably fitted in slots 60 in the side plates of the machine so that they may be readily slid into position or removed for cleaning or repair. The outer transferring roller 9, is connected to the ink-feeding roller 8 by a pair of side links 61 (Fig. 1). The shaft of the outer transferring roller is provided with an eccentric 62 which engages a hole in the outer end of the links 61 so that the ink-feeding rollers 8 are moved up and down and thus are alternately plunged into the ink and pressed against the ink-transferring roller. Thus the ink-feeding roller places a series of daubs of ink on the transferring roller 9 and this is evenly distributed by the transferring rollers. This prevents an oversupply of ink to the printing roller. The rinting roller 1 is carried by a yoke 63 Figs. 1 and 4), the upper bar 64 of which slidably accommodates a vertical pin 65 around which a compression spring 66 is positioned. The outer end of the compression spring bears against a cross bar 67 connected at its ends to the frame of the machine and carrying the pin 65 in a central position. The lower end of the spring presses the yoke 63 downwardly and consequently holds the printing roller firmly against the paper strip. If it should be desired to supply the adhesive paper without the printing thereon, the printing roller may be raised out of contact with the paper strip by means of an eccentric 68 (Fig. 1) fitted in the frame of the machine and adapted to turn so as to press against the lower ends of the arms of the yoke 63 and forces them upwardly against the action of the spring 66, thus raising the printing roller out of engagement with the paper. The printing roller 1 may be constructed as shown in Fig. 4 in which a barrel portion 69 is held between cheek plates 70 carried on a spindle 71 and locked by means of nut 72. This construction enables the barrel 69 to be replaced by similar barrels bearing different advertising matter.

The machine may be provided with ad justable paper guides, paper-supporting table, or other known fittings, if desired.

The word type in the phrase typecarrying printing roller is used in its broad sense to include not merely letters, numerals and like characters but also designs and ornamentation.
