ABSTRACT:
The device has a continuous adhesive-applying surface which is made up from a plurality of elements, articulated so as to enable the configuration of the surface to be varied by varying the relationship between the elements. More particularly, the elements comprise two base elements pivotally connected to one another and forming the base of the U, and two leg elements one pivotally connected to each of the base elements, forming the legs of the U. For adjusting the configuration of the surface, the distance between the pivotal connections of the leg elements with the base elements and also the distance between the remote ends of the leg elements are adjustable. For use in a pulling over and toe lasting machine, the central pivot between the two base elements is fixed in the machine so as to maintain the toe end of the applicator device in the correct relationship with other operating instrumentalities of the machine.
