Abstract
A method of bonding a label having a thermosensitive adhesive provided on the under surface thereof which comprises providing a label from a supply roll, severing same therefrom and delivering such to a heat transferrable conveyor, providing heat to said conveyor, both during travel and interruptions thereof, for rendering said label tacky, peelingly removing said tackified label from said conveyor in timed relation to an article or object traveling thereby for disposition thereon. Apparatus for accomplishing the series of operations in the above-described method for rendering a thermosensitive adhesive equipped label tacky and automatically applying same to the object to be labeled.
Claims15
A method of labelling by use of a thermosensitive adhesive label equipped on the back thereof with a thermosensitive adhesive exhibiting tackiness upon heating and having no separate backing, said method comprising the steps of:
- placing said thermosensitive adhesive label on a heat-resistant conveyor belt;
- conveying said thermosensitive adhesive label while heating said thermosensitive adhesive so that said adhesive develops its tackiness;
- directing the path of said label by means of said heat-resistive conveyor belt so that said path approaches the path of a moving object article to be labelled in converging relationship;
- peeling said thermosensitive adhesive label from said heat-resistant conveyor belt by acutely bending said heat-resistant conveyor belt at a point proximate to a point of convergence of the path of said label with the path of said object article;
- and bonding said thermosensitive label to said object article whereby said object article is caused to be labelled.
In apparatus for bonding a thermosensitive adhesive label to an object article to be labelled, said label carrying on the back side thermosensitive adhesive exhibiting tackiness upon heating thereof and having no separate backing, said apparatus including a heat-resistant conveyor belt for carrying said label along a first path and a further conveyor belt for carrying said object along a second path, said paths converging, means for heating said label while being carried along said first path, the improvement characterized by means for causing said heat-resistant conveyor belt to define an acute bend at a point proximate the convengence of said first path with said second path, said acute bend being sufficient for causing said label to be stripped from said heat-resistant conveyor belt for being transferred to said object article.
