Abstract A device for controlling the length of feed-out of strip material and for regulating the cut-off of the strip material in accordance with the printing of information thereon includes a printing cylinder or drum which engages the strip material as it is fed and imprints it with legend or code. The drum is arranged to rotate in engagement with the surface of the strip material and to transfer an impression thereon during the rotation. Means are associated with the drum for regularly energizing switch means to stop the feed of the strip material and to actuate or permit a cutting device or knife to sever the strip material in lengths corresponding to the desired length as set by the impression printed thereon by rotation of the printing roller. The knife is advantageously actuated and the feed rollers are disengaged by a solenoid which is controlled by a switch operated by rotation of the drum and which is deenergized to permit the movement of the knife through a cutting path under the influence of a return spring to sever the strip material. For this purpose the printing drum carries one or more magnets which trip a switch during the rotation thereof by magnetic action. The device includes feed rollers which engage the strip material and feed it through a dispensing path and these rollers are driven by a motor which is controlled by rotation of the printing roller.
A strip material dispenser comprising a reel supply of strip material, feed roller means for feeding said strip material from said reel supply and for projecting it out for dispensing, a printing cylinder rotatably mounted adjacent said strip material which is being fed off said reel supply and having a periphery engageable with the surface thereof for printing an impression on said strip material, a knife movable across the path of said strip material for severing said strip material after it has been printed, knife actuating means connected to said knife to move said knife to sever said strip material, means including a magnet and a magnetically operable switch, one of which is positioned adjacent said printing cylinder and the other of which is rotated therewith to sense the rotational position thereof, said switch being connected to said knife actuating means to permit movement of said knife actuating means in order to cut the strip material in accordance with the impression left therEon by said printed roller as determined by the position of said printing roller as determined by the coming of said switch and said magnet into close proximity, said magnet be carried on said printing cylinder at a predetermined location, said switch being located alongside said cylinder and being operable by said magnet, means defining a groove on said cylinder carrying said magnet, said magnet being movable along said groove from an operative to an inoperative position, a spring engaged with said magnet and holding said magnet in a selected position said spring being flexible to permit shifting of said magnet to another position, said magnet being shiftable in a radial direction and being operative when it is located adjacent to the periphery of said printing cylinder.
