The dough strings continually discharged from the extruder, are cut off to a certain length, then placed on the sticks and cut to the required length on the lower end. Subsequently, the covered sticks are transferred to the dryer. The empty sticks are taken over by the stick return conveyor and can be heated or treated with edible oil before they are covered with product anew. The cut product remnants are usually transported away from the spreader by means of conveyor belts and are fed to the extruder by means of a pneumatic conveying line. In order to prevent the still wet product on the sticks sticking together, it is necessary to have venting devices at several spots. The spreader can also be equipped with a device for introducing or removing the sticks 3.2 stripping and cutting machine (fig.2) The stripping and cutting machine is positioned after the cooler or after the stick stacker. The stick with the dried product are taken over, the product is stripped off the sticks and is cut to the desired length. The cut product is discharged via oscillating conveyors or conveyor belts and is transferred to the packaging unit or to a stacker. The cut-off material is in most cases transported away by means of a pneumatic conveying line. The empty sticks are transferred to the stick return conveyor. Normally, the stripping and cutting machine comprises also a stick removal device, which takes off the empty sticks to allow for their cleaning or repair.
3.3 stick return conveyor and stick magazine (fig.3) The stick return conveyor brings the empty sticks from the stripping and cutting machine back to the spreader. This device is usually positioned underneath the dryers.

EN 13379:2001+A1:2013 (E) 8 In certain cases one of the functions of this return conveyor is the formation of a stick magazine with the sticks being transported possibly in several tiers. A further stick magazine, called intermediate stick magazine, for a small number of product-covered sticks, can become necessary for plants working without a stick stacker. In this case, the intermediate stick magazine is placed ahead of the stripping and cutting machine. Figure 3 shows the arrangement of the return stick conveyor and the stick magazine within a long-pasta line. SIST EN 13379:2002+A1:2013

crushing hazard; cutting or severance hazard; entanglement hazard; shearing hazard;
impact hazard; The examples shown in figures 1, 2 and 3 illustrate the danger zones associated with these hazards.

4.2.2 Mechanical hazards at the spreader (see fig. 1) 4.2.2.1 Automatic lifting of the inlet hood at the start of production creates, a danger zone at this location. When the inlet hood is lifted, hands or fingers of operators can get squeezed between the die and the inlet hood; when the hood is lowered, the danger area is underneath the inlet hood (zone 1). 4.2.2.2 The upper cutter for cutting the extruded product represents one particularly hazardous zone. For starting production, the inlet hood is pushed out of the way or is removed and the product extrudes until the discharge is uniform. In this situation, the cutting device may become accessible, which means that fingers and hands of operators are exposed to risk of injury (zone 2). 4.2.2.3 The lower cutter, which cuts the product on the sticks to equal length also represents an area which is particularly hazardous. For maintenance and cleaning, there is free access to the cutter, because the guards have been opened, and there is danger of severe cuts of the fingers and hands (zone 3). 4.2.2.4 The empty sticks being moved on the front of the machine for spreading with product also represents an area which is particularly hazardous. There is a risk of injury (pinching) (zone 4). 4.2.2.5 The conveying belts with the danger of body-parts being drawn-in are further hazard zones (zone 5). 4.2.2.6 The fans for venting the product can cause injuries, such as finger amputation (zone 6). 4.2.2.7 The shredder fan used for transporting the cut-off material back to the extruder can amputate fingers or hands during cleaning. In addition to this, the rotor has accumulated kinetic energy, which can also lead to injuries for a certain time after the machine was shut down (zone 7). 4.2.2.8 The chain transmissions for moving the stick can also cause injuries by pinching and drawing-in (zone 8). 4.2.3 Mechanical hazards on the stripping and cutting machine (see fig. 2) 4.2.3.1 The cutting device, which usually comprises rotating cutter blades is especially dangerous. There is a risk of severe laceration. The energy accumulated in the cutters represents another danger, as the cutters will continue to turn for a certain time after the machine has been shut down; injuries might result. Another hazard is parts coming loose from the cutter blade, such as hard metal teeth, which are thrown off and may cause injuries (zone 1). 4.2.3.2 The stripping and depositing devices represent additional hazard zones. Here, especially the clamping zones may cause danger of pinching (zone 2). 4.2.3.3 The conveying elements for the stripped off and cut or uncut product, such as chains, belts or oscillating conveyors, can cause injuries by pinching and drawing-in (zone 3). 4.2.3.4 The chain transmission and possibly the disk cams of the stick drives, as well as of the stripping device, can cause injuries (pinching) (zone 4). 4.2.3.5 The fan for transporting the remaining product back to the milling device, may cause injuries to the fingers or hands during cleaning. In addition to this, the rotor has accumulated kinetic energy, which can also lead to injuries for a certain time beyond the point where the machine was shut down (zone 5). SIST EN 13379:2002+A1:2013
EN 13379:2001+A1:2013 (E) 13 4.2.3.6 The side of the cutting machine where the sticks are introduced is normally attached to adjacent machines, for instance to the stick stacker. Uncovered openings and channels may offer free access to the moving parts and thus these may cause injuries by drawing-in and pinching (zone 6). 4.2.3.7 At the stick removal device there is risk of getting injured at the clamping and drawing-in zones (zone 7). 4.2.4 Mechanical hazards at the stick return conveyor and the stick magazine (see fig. 3) 4.2.4.1 In the stick transfer area and along the conveying elements there is risk of pinching at the clamping points that may cause injuries (zone 1). 4.2.4.2 Driving elements such as chain transmissions, rotating shafts, and stick transfer points may cause injuries due to drawing-in and pinching (zone 2). 4.2.4.3 In case of removal and feeding devices of the stick, there is risk of pinching at the clamping points. 4.2.5 Fluid ejection hazards Failure of heating pipings under hydraulic pressure and failure of power hydraulic and pneumatic systems may cause hazard of ejection of fluid which may cause injury (zone 9, fig. 1). 4.2.6 Hazards due to unexpected start or failure of emergency device Unexpected start up or failure of emergency device may cause hazard of contact with dangerous moving parts, with the consequences listed in clause !4.2", !4.3", !4.4". 4.3 Electrical hazards Hazard of electric shock from direct or indirect contact with live components. This hazard is present in control consoles, motor connectors, electrical resistances, etc. Hazard of external influence on electrical components. This hazard is present in running operation of machinery (e.g. caused by interferences to controlling signal or by cleaning with water or steam). 4.4 Thermal hazard Risk of burns exists at the spreader in the case of direct contact with stick heating (zone 9, fig. 1). Furthermore, the high temperatures of heat exchangers for product venting devices, their supply pipes and fittings may cause burns (zone 10, fig. 1). 4.5 Noise hazard Noise generated by these machines can lead to permanent loss of hearing; ringing in the ears; fatigue, stress; interference with speech communication, acoustic signals.
