Method for repairing plastic dividers and plastic divider obtained by said method

A method for repairing plastic dividers comprising longitudinal internal cavities, comprising the following steps:

• identifying a damaged area to be repaired in a plastic divider,
• extracting the damaged area to be repaired previously identified by means of one or more cuts, wherein a gap is defined in the plastic divider, wherein a first edge of the gap in the plastic divider comprises a first pair of plastic layers separated by a first longitudinal internal cavity,
• preparing an insert of undamaged material and with a shape matching said gap, wherein a second edge of the insert comprises a second pair of plastic layers separated by a second longitudinal internal cavity, and
• attaching, by means of one or more heat welds with filler material, the insert of undamaged material in the gap, wherein a first portion of the filler material penetrates into the first longitudinal internal cavity between the first pair of plastic layers and a second portion of the filler material penetrates into the second longitudinal internal cavity between the second pair of plastic layers;
• wherein for the step of extracting the damaged area to be repaired, a cut with a curved path is used, and
• wherein in the step of preparing the insert, the insert is machined to include a straight or angular outer edge, aligned with the edges of the plastic divider, and the second edge, the second edge comprising a curvilinear inner edge parallel to the curved path of the cut for extracting the damaged area to be repaired, there being defined between the cut made in the divider and the inner edge of the insert a filling space for filling with the filler material.
