Abstract
A filter tipping machine wherein pairs of coaxial plain cigarettes are united with filter plugs of double unit length by adhesive-coated bands. When a filter plug is missing, a mechanical or a photosensitive filter plug detector transmits a signal to a valve which admits compressed air to two nozzles to cause the plain cigarettes which are not separated by a filter plug to move toward each other so that a uniting band which is applied around the adjacent inner end portions of the thus shifted plain cigarettes can adequately connect the plain cigarettes to each other during further transport to a station where the united plain cigarettes can be readily segregated from satisfactory products.
Claims13
In a machine for producing filter cigarettes or analogous smokers' products wherein one end of a tobacco-containing first rod-shaped component is connected with a coaxial filter component of unit length by an adhesive-coated uniting band which is convoluted around the filter component and the adjacent end of the first component, the combination of means for transporting successive pairs of coaxial first components sideways along a first path wherein the first components of each pair are separated from each other by a gap;
- means for transporting a series of filter components of double unit length along a second path toward and into a first portion of said first path so that successive filter components of said series enter the gaps between successive pairs of first components;
- means for draping discrete adhesive-coated uniting bands around successive filter components of double unit length and the adjacent ends of corresponding pairs of first components in a second portion of said first path;
- means for monitoring said second path ahead of said second portion of said first path, including means for generating signals in response to detection of the absence of filter components of double unit length;
- and means for moving the first components of the corresponding pairs axially toward each other in response to said signals and ahead of said second portion of said first path.

- means for monitoring one of said paths ahead of said second portion of said first path, including means for generating signals in response to detection of the absence of filter components of double unit length;
- and means for moving at least one of the first components of the corresponding pairs axially toward the other component in response to said signals and ahead of said second portion of said first path.
