The seam of the tubular wrapper for the rod-like filler of tobacco or filter material in a cigarette or filter rod making machine is heated by a first heating element during acceleration of the machine from zero speed to normal operating speed. When the machine reaches the normal speed, the seam is additionally heated by a second heating element whose heating action is more pronounced that that of the first heating element. The first heating element is caused to engage the moving seam when the first increment of adhesive film, which is applied to one marginal portion of the wrapper by a paster, reaches the first heating element. The second heating element is moved into engagement with the seam when the RPM of the prime mover for the filler transporting conveyor reaches a preselected value. Both heating elements are disengaged from the seam in response to deactivation of the prime mover with a delay which corresponds to the interval elapsing between deactivation of the prime mover and the transport of last adhesive-coated increment of the one marginal portion to a position of register with the first heating element.

Device for heating the seams of wrappers for rod-like fillers in

A tray filling apparatus wherein a suction head accumulates rows of cigarettes and a pusher transfers the rows into a tray which is supported by an endless chain conveyor. The suction head and the pusher receive motion from a drive which includes a variable-speed DC-motor, a step-down gearing which is driven by the output shaft of the motor, and a mechanical transmission having a first component which moves the suction head between a lower position in which the latter accumulates a row of cigarettes and one of two raised positions, and a second component which moves the pusher forwardly not later than when the suction head reaches a raised position. The forward movement of the pusher is slower than its return movement to retracted position and the characteristic RPM curve of the motor is determined by a control circuit which includes three signal generators one of which starts the motor, another of which decelerates the motor after the suction head returns to lower position and the pusher reassumes its retracted position, and the third of which arrests the motor while the suction head and the pusher respectively dwell in their lower and retracted positions. A second electric motor drives the conveyor for an empty or partly filled tray through the medium of a second transmission in stepwise fashion upon completion of each forward stroke of the pusher.

Apparatus for filling containers with cigarettes or the like

Successive filter rod sections which are produced in a filter rod making machine are caused to pass through a body of ionized air before they leave the machine. This insures that ionized air destroys the electrostatic charges which the non-conductive wrappers and/or fillers of filter rod sections accumulate in the machine upstream of the ionizing station. The conveyor or conveyors which transport the filter rod sections through ionized air are designed to transport the sections sideways. At least one electrode of the ionizing device or devices for air is preferably connected with a source of high-voltage a-c energy.
