Abstract
An apparatus and method are disclosed for providing a measured quantity of extrudate material to a receiving means. The extrudate material exits through an outlet, and a cutting surface is positioned adjacent to the outlet. The extrudate material is severed by a cutting means having a flexible and resilient blade for severing the extrudate material into metered charges. The cutting blade contacts the cutting surface during each revolution and bends from a rest condition to a backwardly bent flexed condition. After severing a metered charge, the cutting blade is released from the cutting surface and snaps forwardly to the rest condition to propel the metered charge toward the receiving means at a velocity greater than the average tangential velocity per revolution of the cutting blade.
Claims11
An apparatus for providing a metered charge of material to a receiving means, comprising:
- material providing means having an outlet for feeding material which is to be severed into metered charges and deposited in such receiving means;
- cutting means operatively associated with said material providing means for severing said material into metered charges;
- a cutting surface positioned adjacent to said outlet in said material providing means and facing said cutting means;
- said cutting means including a flexible and resilient cutting blade having an axis of rotation, the distance between the distal end of said cutting blade and the axis of rotation being greater than the distance between the axis of rotation and said cutting surface;
- and
- means connected to said cutting means for driving said cutting means at a substantially uniform rate of rotation;
- so that said rotating cutting blade contacts said cutting surface and bends from a rest condition to a backwardly bent flexed condition in which said cutting blade severs a metered charge from said material with a wiping action, and said cutting blade is released from said cutting surface after severing said metered charge and snaps forwardly into said rest condition to thereby accelerate and propel such metered charge toward said receiving means at a velocity greater than the average tangential velocity per revolution of said cutting blade.
An apparatus for providing a metered charge of material to a receiving means, comprising:
- material providing means having an outlet for feeding material which is to be severed into metered charges and deposited in such receiving means;
- cutting means operatively associated with said material providing means for severing said material into metered charges;
- an arcuate cutting surface positioned adjacent to said outlet in said material providing means and facing said cutting means;
- said cutting means including a flexible and resilient cutting blade having an axis of rotation which is approximately the center line of said arcuate cutting surface, the distance between the distal end of said cutting blade and the axis of rotation being greater than the distance between the axis of rotation and said cutting surface;
- and
- means connected to said cutting means for driving said cutting means at a substantially uniform rate of rotation;
- so that said rotating cutting blade contacts said cutting surface and bends from a rest condition to a backwardly bent flexed condition in which said cutting blade severs a metered charge from said material with a wiping action, and said cutting blade is released from said cutting surface after severing said metered charge and snaps forwardly into said rest condition to thereby accelerate and propel said metered charge toward such receiving means at a velocity greater than the average tangential velocity per revolution of said cutting blade.
