Abstract
The sizing part of the wrapping mechanism in a cigarette rod making machine has a channel-shaped member with a guide surface extending between a straight edge and a U-shaped edge and composed of an infinite number of straight lines each of which connects a point on one of the edges with a point of the other edge. The channel-shaped member cooperates with a tongue whose sides define with the adjacent mutually inclined sections of the guide surface two gaps of constant width for the passage of the marginal portions of garniture tape which is used to drape the web of cigarette paper or other wrapping material around a filler of tobacco or filter material.
Claims9
In a wrapping mechanism for use in a rod making machine of the tobacco processing industry, a sizing part including a channel-shaped member having a first edge with a first outline, a second edge remote from said first edge and having a second outline which differs in shape from said first outline, wherein one of said edges is a substantially straight edge, and a guide surface extending between said edges and having a configuration such that each of an infinite number of straight lines forming said surface extends from one of an infinite number of portions of said first edge to one of an infinite number of portions of said second edge.
In a rod making machine of the tobacco processing industry, a sizing part comprising a channel-shaped member having a first edge, a second edge remote from said first edge, one of said edges being substantially straight and the other of said edges being substantially U-shaped, said member further having a guide surface extending between said edges and composed of an infinite number of straight lines each connecting one of an infinite number of points on said first edge with one of an infinite number of points on said second edge;
- an endless flexible garniture tape having an elongated reach overlying and conforming to said guide surface;
- and means for driving said tape in a direction from said first edge toward said second edge.
