A cutting module for cutting a strand into individual pieces, the cutting module comprising a rotatable cutter wheel and a rotatable cot wheel, the cutter wheel being rotatable and having cutting blades, the cot wheel having a cylindrical outer surface and being rotatable parallel at a distance from the cutter wheel, such that cutting edges of the cutting blades contact the outer surface of the cot wheel successively in use, so that a strand which is fed between the cutter wheel and the cot wheel is cut into individual pieces, each of the cutting blades being designed such that a cutting force is directed through the cutting blade.

Cutting module and method for cutting a strand into individual pieces

The present application relates to process for producing a glass fibre-reinforced thermoplastic polymer composition, which comprises the sequential steps of: The unwound, the at least one continuous glass multifilament strand is transported through the inside of at least one protective tube over a certain distance between the location of unwinding from a package of said at least one continuous glass multifilament strand, i.e. step a), and the location of applying said sheath of thermoplastic polymer around said at least one continuous glass multifilament strand, i.e. step b).

Process for producing a glass fibre-reinforced thermoplastic polymer composition

The present invention relates to a process for the manufacture of a long glass fibre reinforced polypropylene composition. The process comprises: a) providing at least one continuous glass multifibre strand, b) applying a sheath of a polypropylene composition around said continuous glass multifibre strand so as to form a sheathed continuous glass multifibre strand, c) cooling the sheathed continuous glass multifibre strand to a cutting temperature, d) cutting the sheathed continuous glass multifibre strand into pellets using a rotary cutting tool at a cutting temperature that satisfies the following equations I, II and III_max=&#x2212;0.625&#xd7;GF+112.5&#x2003;&#x2003;(I)T_min=10&#x2003;&#x2003;(II)T_min&#x2264;T_cut&#x2264;T_max&#x2003;&#x2003;(III)wherein: T_cut is the cutting temperature, T_max is the maximum cutting temperature [&#xb0; C.], T_min is the minimum cutting temperature [&#xb0; C.], and GF is the amount of glass fibres based on the weight of the composition [wt. %].
