Abstract
Abstract The continuous presence and availability of gathered netting for filling of foodstuff into a receiving net by means of a tubular extruder is ensured by the present semi-automatic apparatus, which provides for the automatic reciprocating motion of a carrier which gathers the net around the outlet of the extruder while at the same time, a photo electric eye controls the unfolding of the net and the stuffing operation of the process, by stopping the motor which drives the carriage and causing a fresh length of netting to be automatically positioned at the outlet of the extruder.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
138 words
Semi-automatic apparatus for stuffing foodstuff into tubular netting, wherein a predetermined quantity of netting is gathered by means of a sliding carriage upon a tubular extruder, comprising the combination of: a gathering carriage having a pitman-connecting link mechanism provided therewith; a motor for actuating said mechanism; a photo electric switch means for controlling the drive of said motor, said photo electric switch means being responsive to the presence of netting gathered in correspondence with a reference line provided on said extruder in the vicinity of the outlet thereof; a fluid-tight and freely slidable extruding piston within the body of said extruder, said piston being actuated by a compressive fluid; control means for introducing said fluid against said piston and for concurrently unfolding a predetermined quantity of said netting proportionately to the volume of said foodstuff to be stuffed.
Claim 2
Dependent Claim
138 words
Semi-automatic apparatus for stuffing foodstuff into tubular netting, wherein a predetermined quantity of netting is gathered by means of a sliding carriage upon a tubular extruder, comprising the combination of: a gathering carriage having a pitman-connecting link mechanism provided therewith; a motor for actuating said mechanism; a photo electric switch means for controlling the drive of said motor, said photo electric switch means being responsive to the presence of netting gathered in correspondence with a reference line provided on said extruder in the vicinity of the outlet thereof; a fluid-tight and freely slidable extruding piston within the body of said extruder, said piston being actuated by a compressive fluid; control means for introducing said fluid against said piston and for concurrently unfolding a predetermined quantity of said netting proportionately to the volume of said foodstuff to be stuffed.
Claim 3
Dependent Claim
48 words
The apparatus according to claim 1, wherein said carriage for the gathering of said netting includes jaw-like retaining means comprising at least two resilient jaws connected to said carriage so as to be capable of swinging motion in a horizontal plane and against the action of corresponding springs.
Claim 4
Dependent Claim
29 words
The apparatus according to claim 1, wherein said pitman-connecting link mechanism is actuated by a flywheel, said flywheel being moved by a gear reducer operatively connected to said motor.
Claim 5
Dependent Claim
52 words
The apparatus according to claim 1, wherein said photo electric switch means comprise a photo electric cell operatively associated with a screen, said screen being connected with said carriage for rendering inoperative said photo electric cell whenever said pitman-connecting link mechanism is in the maximum swinging horizontal position obtainable by said pitman.
Claim 6
Dependent Claim
38 words
The apparatus according to claim 4, wherein the outer surface of the extruder and the surface of said screen are reflective surfaces capable of activating said photo electric cell, said cell upon activation causing said motor to stop.
Claim 7
Dependent Claim
38 words
The apparatus according to claim 1, wherein said control means for introducing said fluid against said piston comprise a valve-actuated nozzle, a swinging arm for supporting said nozzle, and a flexible control cable to actuate said swinging arm.
Claim 8
Dependent Claim
42 words
The apparatus according to claim 6, wherein said nozzle is normally detached from the inlet to the extruder, said nozzle approaching said inlet as a result of the swinging motion of said arm, said arm controlling a microswitch for arresting the motor.
Claim 9
Dependent Claim
57 words
The apparatus according to claim 1, wherein said netting is unfolded from said extruder by means of the action of a control block, said block engaging the outlet of Said extruder at the outer rim thereof and disengaging said outlet rim by means of a swinging action produced by another flexible cable cooperative with said control pedal.
Claim 10
Dependent Claim
21 words
The apparatus according to claim 8, wherein said control block is substantially U-shaped, and contains the blade of a web-slitting means.
