Abstract

A guide for use in loading a paper web into the web drive mechanism of a printer is provided with two hooks. In order to feed the web into the drive mechanism the leading end of the web is placed on the hooks, which engage with holes in the sides of the web, so that the leading edge of the web is located in the drive mechanism. Operation of the drive mechanism pulls the web off the hooks and then drives the web normally. This arrangement is illustrated diagrammatically in the figures, in which Fig. 1 is a front view of part of the paper web drive mechanism of a printer and Figs. 2 and 3 are side views of the drive mechanism showing the leading end of the web placed in position for engagement with the drive mechanism. Fig. 4 is a side view of an alternative arrangement. As shown in Figs.

Hooked Guide for Loading Paper Web Into Printer

A guide for use in loading a paper web into the web drive mechanism of a printer is provided with two hooks. In order to feed the web into the drive mechanism the leading end of the web is placed on the hooks, which engage with holes in the sides of the web, so that the leading edge of the web is located in the drive mechanism. Operation of the drive mechanism pulls the web off the hooks and then drives the web normally. This arrangement is illustrated diagrammatically in the figures, in which Fig. 1 is a front view of part of the paper web drive mechanism of a printer and Figs. 2 and 3 are side views of the drive mechanism showing the leading end of the web placed in position for engagement with the drive mechanism. Fig. 4 is a side view of an alternative arrangement. As shown in Figs. 1,2 and 3, a continuous paper web 1 is driven into a printer 2 by means of two tractor wheels 3 formed with pins 4 which are adapted to engage with holes 5 in the sides of the paper web. The web is supported on two guides 6, each of which is formed with a hook 7. In order to load web 1 into the drive mechanism, the leading end of the web is placed on the guides 6 so that the hooks 7 engage in the holes 5. The leading edge of the web will be then located in either one of the positions illustrated in Figs. 2 and 3, depending on the rotational positions of the tractor wheels 3 and thereby the positions of the pins 4. In the arrangement illustrated in Fig. 2, the pins 4 are positioned so that the leading edge 8 of the web extends between two adjacent pins 4 on each of the tractor wheels 3 and lies flat on the guides 6. In the arrangement illustrated in Fig. 3, the pins 4 are positioned so that the leading edge of the web abuts against one of the pins 4 and is raised off the surface of the guide, forming a buckle 9. If the tractor wheels 3 ar...
