Continuous strip materials supplied in rolls are spliced automatically at the moment of use by a series of steps in which the leading end of the strip decoiled from a new roll is arranged first on the locating and striking face of a suction bar capable of movement between an at-rest position and a splicing position, whereupon the trailing end of the depleted strip decoiling from the roll still in use is restrained against a fixed reference surface coinciding with the splicing position, a transverse cut made through the trailing end of the depleted strip, and the leading end of the new strip brought into contact with the area of the trailing end of the depleted strip terminating in the cut, and the joined ends are then secured by heat-sealing or by applying an adhesive or a double-sided sticker.

A device for automatically splicing strips decoiled from rolls of material, comprising: a fixed reference surface over which a depleting strip can be advanced; a movable restraint assembly capable of movement between first position in which the restraint assembly is spaced from the fixed reference surface and a second position in which the restraint assembly is moved into engagement with said fixed reference surface so as to hold a trailing portion of the depleting strip motionless therebetween; a cutting assembly capable of movement to effect a transverse cut through the trailing portion of the depleting strip as the depleting strip is held motionless between the fixed reference surface and the restraint means so as to form a cut end of the trailing portion of said depleting strip; a movable retaining assembly capable of transferring a leading portion of a new strip of material from a position in which the leading portion is spaced from the trailing portion of said depleting strip to a position in which the leading portion is forced into engagement with said trailing portion adjacent said cut end; and a securing assembly for providing a securing material between said leading portion of said new strip and said trailing portion of said depleting strip so that said leading portion and said trailing portion are secured to one another after being brought into engagement by said retaining assembly .
