Abstract: Succesive lowermost coupons of a stack in a magazine are withdrawn by suction heads borne by a turnable suction wheel and a pivotable arm to be advanced along one or more arcuate first guides into a second guide which directs the coupons to predetermined positions beneath discrete U-shaped collars of the type forming part of so-called hinged lid packs for confinement of plain or filter cigarettes or other smokers' products. A coupon which has assumed such predetermined position is thereupon expelled from the second guide and is confined, together with the collar and the pack, in an outer envelope of cardboard or the like. An advantage of the method and apparatus is that the collar need not be lifted during advancement of a coupon to its predetermined position to thus reduce the likelihood of misalignment of the collar and the coupon relative to each other preparatory to and during their confinement in the outer envelope of the ultimate product.

Abstract: Methods, systems, and apparatus consistent with the present invention use a beam of laser energy to concentrically form an optical preform from two or more concentric glass objects, such as two glass tubes or a hollow glass tube and a solid glass rod. The glass objects are placed in a concentric configuration where the outer object has an inner surface that is placed proximate to an outer surface of the inner object. Once these are assembled, a beam of laser energy is generated, positioned, and applied to a starting point in the gap defined by the inner surface and the outer surface. Once the laser beam is applied and is reflecting down into the gap, the beam of laser energy is moved relative to the starting point as the beam is concurrently applied. This heats the inner surface and outer surface so that the two objects can be joined to form the optical preform. In another aspect of the invention, a coating layer is disposed within the gap and can be heated by the laser as it is applied within the gap.
