ABSTRACT:
A film assemblage comprising a spool core, and a filmstrip, a film leader and a film trailer which are to be wound as a single longitudinal strip on the spool core in a roll with the filmstrip extending between the film leader and the film trailer in order that the film leader, the filmstrip and the film trailer form a common inner side of the roll and a common outer side of the roll, is characterized in that the film trailer has a discrete cohesive patch located to be on the inner side of the roll and a discrete cohesive patch located to be on the outer side of the roll, which can only stick to one another other and not to the inner or outer sides of the roll, and which are spaced apart along the film trailer a distance substantially equal to the circumference of the roll, whereby when the film leader, the filmstrip and the film trailer are wound on the spool core with the film trailer being an innermost convolution of the roll and the film leader being an outermost convolution of the roll the cohesive patches will be separate from each other to prevent them from sticking to one another, but when the film leader, the filmstrip and the film trailer are wound on the spool core with the film leader being the innermost convolution of the roll and the film trailer being the outermost convolution of the roll the cohesive patches will be facing each other to stick to one another.
