Apparatus for wrapping drinking straws
First Claim
1. Apparatus for confining elongated open-ended sipping straws in discrete envelopes, comprising:
- a facility for temporary storage of an accumulation of unconfined straws;
means for transporting at least one file of spaced-apart successive straws from said facility lengthwise along a predetermined path;
means for advancing to a predetermined portion of said path a strip of wrapping material having two marginal portions;
means for applying adhesive to at least one marginal portion of the strip not later than in said portion of said path;
means for draping the strip around successive spaced-apart straws in said portion of said path so that the at least one marginal portion overlies and adheres to the other of said marginal portions; and
means for severing the draped strip between successive confined straws.

Abstract
Sipping straws are confined in discrete envelopes while advancing in a single file of spaced-apart straws through a wrapping station. The envelopes are obtained from a continuous strip of wrapping paper which is conveyed to the wrapping station in the direction of advancement of the file of spaced-apart straws and is draped around the straws in such a way that one of its longitudinally extending marginal portions overlies and adheres to the other marginal portion with simultaneous formation of a seam rather than an outwardly extending fin. The thus obtained tubular wrapper is thereupon severed in the gaps between successive spaced-apart straws, and the end portions of the thus obtained discrete envelopes are sealed by knurling, e.g., simultaneously with severing of the tubular wrapper.
