In one embodiment a hand operated machine for making curly ribbon products comprises a rotary drum that includes a station to attach the uncurled ribbons (more than one), a cutting station to cut the curled ribbons, and a stapling station to staple the ribbons together or to a card, ribbon, or the like. A handle is provided to rotate the drum and a fixed curling mechanism mounted downstream of the drum serves to curl the ribbon as the drum rotates to place the ribbon in contact with the curling mechanism. In another embodiment the machine is automated and includes a drum that has the same stations. The attaching station includes a pair of jaws that are sequentially movable one relative to the other and together to attain attaching the ribbons to the drum for the first cycle, detaching the ribbon during the first cycle and attaching the succeeding ribbon used in the next cycle for mass producing the curly ribbon product. The stapling and cutting are automatic and the card feeding machine is movable relative to the drum to avoid snarling the ribbon when released. The curling mechanism is adjustable to change the exit angle to select the desired curl characteristics of the curled ribbon.

A portable bow making machine with three clutches controlling the size, arc generation and a no-back clutch assuring that the belt driving the impaler assembly doesn't go into reverse The user requiring no particular skill, merely threads the ribbon in a channel under the reciprocal carriage and the two stroke operation automatically makes one of the loops of the bow. Stroking continues until the bow is complete and a stapler automatically retracts the needles of the impaler and the staple is forced against an anvil to secure the bow. The stapler is configured to hold a removable self-gluing card that is concomitantly attached to the bow. The forward stroke carries a carriage and clapper along the carriage slides, The clapper reaches a predetermined point and drops onto the impaler to secure each of the loops to the bow. The return stroke repositions the carriage for the next forward stroke.

An easy to clean and sanitize skewer driver for driving the horizontally supported skewer in the rotisserie oven for roasting chickens and other food products is formed from an outer and an inner sleeve where the inner sleeve is affixed to a planet gear and is journalled in the outer sleeve for rotary motion. A pin bisecting the inner sleeve retains the inner sleeve and planet gear and defines a recess or socket for accepting the end of and driving the skewer for rotation about its own axis, The outer sleeve is frictionally fitted to the reel plate to orbit in the rotisserie oven so that the skewer rotates with and relative to the reel plate.

The bull gear in the planetary gear system of a rotisserie is mounted on the shaft of the reel plates and held stationary for rotating the plantetary gears and maintaining them in a coplanar relationship. The bull gear is biased by a spring having its free end bearing against the face of the bull gear to urge it axially toward the reel plate. The bull gear and planet gears are selected so that the rotational speed of the skewer driven by the planet gear and the orbital speed of the reel plate are such that the same angular location of the skewer passes the same angular location of the heater once every five orbits.

The skewer for a rotisserie for roasting chicken and the like is formed from a single piece with a straight spine portion having angularly extended drive wings fitting into the cavity of the chicken for positive rotation thereof. The skewer rotates with the reel plate of the rotisserie and relative to and includes support ends for mounting in the reel plates of the rotisserie that include constraints for limiting axial movement for precluding the possibility of inadvertent dislodgement of the skewer from the reel plates. The absence of corners, welds and crevices and the like facilitate cleanliness and avoids the propensity of collecting bacteria and potentially toxic substances.
