Vorrichtung zum Vorwärtsbewegen eines Trägerstreifens

摘要

A label printer for receiving a continuous strip of labels on a backing strip from a label supply and for passing the labels between a thermal first head and a platen roller. A motor connected with the platen roller rotates the platen roller. A peeling rod located past the thermal head in the path of the backing strip about which the strip is sharply deflected for separating the labels from the backing strip. A rotatable presser roller opposite the platen roller and past the peeling rod for pressing the backing strip with the labels now removed against the platen roller, whereby the label strip is driven by the platen roller past the thermal head and the backing strip is driven by the rotation of the platen roller and the cooperating rotation of the presser roll again past the platen roller. The presser roll is supported by a support having positioning notches for selectively positioning the presser roll either engaging the platen roller or spaced from the platen roller, the latter position permitting threading of the strip member between those rollers. A spring normally urges the presser roller toward the platen roller. When the presser roller is supported in the support, it is held against the spring.
