Abstract: Carrier attachments on a roller chain receive a bottle cap for printing at a loading station formed at the discharge end of a downwardly-inclined chute. A top constrainment member is normally spaced from the top of the carrier attachments at the loading station by a distance less than the height of the bottle caps in the supply chute to prevent advancement of the caps until an underlying carrier attachment advances beyond the bottom support surface of the cap. The constraining member is resilient to urge the article into the space between the attachments according to one embodiment or according to a second embodiment, the article drops onto a carrier. The article is supported by surfaces on guide rails during movement to a printing station by the conveyor.

Abstract: A connector apparatus to couple an electrical cable of a low-voltage power supply to an electrically-resistive heater strip carrying a layer of thermoplastic adhesive. The connector includes an elongated housing having a projecting support leg and a clamp jaw at opposite ends of the housing to support the housing so as to extend in a downwardly-inclined manner. The walls of the housing form an open cavity which is adapted to receive a helical spring through which a cable extends from an end wall of the housing to a connector used to secure the end of the cable to a bus bar. The bus bar is guided for movement along the length of the housing. The bus bar is urged by the spring toward the clamp jaw to grip the edge of the electrically-resistive heater strip used to heat in situ the thermoplastic adhesive that forms carpet seaming tape.
