Apparatus for welding together thermoplastic hoses

An apparatus for welding together thermoplastic hoses, said apparatus having an open position and a closed position, said apparatus comprising:

• a first clamping unit having two first clamping jaws with first through-passages;
• a second clamping unit having two second clamping jaws with second through-passages, said first through-passages and said second through-passages being provided for inserting the thermoplastic hoses parallel to each other and squeezing the thermoplastic hoses traverse to each other;
• said first clamping unit and said second clamping unit being capable of being shifted from and to the open position and the closed position;
• a heatable blade for cutting through the thermoplastic hoses and creating cut edges of the respective thermoplastic hoses, said heatable blade melting the respective cut edges of the thermoplastic hoses between said first clamping unit and said second clamping unit,
• a first intermediate piece between said first clamping jaws and a second intermediate piece being located between said second clamping jaws for separating the thermoplastic hoses from each other in the closed position;
• wherein at least one of said first clamping unit and said second clamping unit further comprises inner clamping jaws, said inner clamping jaws being held by one of said two first clamping jaws and said two second clamping jaws;
• said inner clamping jaws and said one of said two first clamping jaws and said two second clamping jaws being capable of being jointly adjustable with said at least one of said first clamping unit and said second clamping unit, and
• said inner clamping jaws and one of said first intermediate piece and said second intermediate piece capable of being turned with respect to each other during the closed position in said one of said two first clamping jaws and said two second clamping jaws.
