FIELD: welding.
SUBSTANCE: invention relates to machine (1) for welding plastic shaped elements comprising: main frame (6); a pair of retaining elements (7, 8) configured to hold corresponding plastic shaped elements (P) having respective regions (Z) to be welded with first main edge (2a), second main edge (3a), first side edge (4a) and second side edge (5a); heat-sealing element with heating plate (11); means (9, 10) for sliding of retaining elements (7, 8); removing means (13, 14) configured to remove material from regions (Z) to be welded on at least first side edges (4a); lateral limiters (23, 24), which are made with possibility of resting in regions (Z) to be welded on first side edges (4a) to limit side surfaced roll (S) and which contain at least V-shaped element (23), having two sides (25), located in V-shaped configuration and made with possibility of resting against at least part of corresponding first side surfaces (4) of shaped elements (P).
EFFECT: technical result achieved when using the machine under the invention consists in ensuring production of frames of higher quality and simplification of the process of welding plastic shaped elements for making frames.
