25、14-3:2001+A1:2008 (E) 4 Introduction This document is a type C standard as stated in EN 1070. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C standard are different from t
26、hose which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. 1 Scope This European Standard contains the safety re
27、quirements for the design and construction of haul-offs used in extrusion lines for processing plastics and rubber for the hazards identified in clause 4. The following kinds of haul-offs are covered: caterpillar haul-offs; belt haul-offs; capstan haul-offs; belt capstan haul-offs; roller haul-offs.
28、 The machine begins at the material inlet opening and ends at the material outlet. Cutting units which are integrated with or attached to the haul-off are not covered. Take-off devices used at film or sheet lines are not covered. Chemical, toxicological and fire hazards which could occur for example
29、 in continuous vulcanisation plants due to the materials processed are not dealt with. Unwinding and winding machines are not subject to this standard. They are being dealt with in a separate standard being produced by another working group of CEN/TC 145. This document is not applicable to haul-offs
30、 which are manufactured before the date of publication by CEN of this document.

43、 definitions given in EN 1070 and the following terms and definitions apply: 3.1 haul-off a powered device used in extrusion lines to continuously haul off products such as cable, cable core, profiles, pipes or tape. lt operates by pulling the product by means of friction between the product and the
44、 moving gripping elements. 3.2 caterpillar haul-off a device comprising two or more sets of linked elements equipped with gripping segments or lugs; one or more are driven. Grip is achieved when the elements are closed together by pressing the product between them (see figure 1). 3.3 belt haul-off a
45、 device comprising two counter-rotating belts set in line one above the other; one or both is driven. Grip is achieved when the belts are closed together by pressing the product between both belts (see figure 2). 3.4 capstan haul-off a device comprising one or more drums or wheels at least one of wh
46、ich is driven. Grip is achieved by the tension of the product, e.g. cables, flexible hoses, wrapped one or more times around the drum(s) or wheel(s) (see figure 3). 3.5 belt capstan haul-off a device comprising a wheel and a belt which covers at least partially the circumference of the wheel. The wh
47、eel, the belt or both are driven. Grip is achieved by pressing the product between the belt and the wheel (see figure 4). 3.6 roller haul-off a device comprising one or more sets of counter-rotating rolls set in line one above the other; one roller or both of each set is driven. Grip is achieved by
48、pressing the product between the rollers (see figure 5).
