Abstract: A combination of a sonotrode and anvil, includes a sonotrode/anvil surface and a first row of sonotrode/anvil welding contact elements. The first/second series of each of the sonotrode/anvil welding contact element of a first row includes a first/second adapted lateral surface that joins at least one part of the first/second plateau surface with at least one part of the sonotrode/anvil surface side. The first/second adapted lateral surface includes a first/second curved surface positioned between the first/second plateau surface and the first/second substantially straight surface. The first/second curved surface has a convex outward arch. The welding contact element is positioned in relation to the anvil welding contact element such that the sonotrode welding contact element is positioned during welding next to the anvil welding contact element and is provided to form at least one part of a weld seam.

Abstract: A blow mould includes at least first and second blow mould elements that inscribe a concavity; and at least one insert having an embossed surface to form a pattern onto a blow-moulded surface. The at least one insert is attached onto a surface of at least one of the first and/or second blow mould elements to form a part of the wall of the blow-moulded product. Such blow mould is an ISBM blow mould and the blow mould is such that the at least one insert is a plate having a wall thickness of between 0.2 mm and 2.0 mm and is attached onto at least one of the first and/or second blow mould elements by a reversible fixation mechanism selected from the group of adhesives, preferably a double-sided adhesive tape, a magnet and a geometric mechanism.

Abstract: Method for manufacturing plastic preforms (10) by injection moulding, consisting of sub-preforms (11, 12) injected at the same time, wherein (?1) the injection mould (3) containing the injected composite preform (10) and secondary sub-preform (12) is 1 st closed, and a gripper (4) provided with a set of receiving members (16) is set in a standby position (A) aside from the mould (3); in a 2nd step (?2) the mould (3) is opened, wherein each primary core (33) bears an injected composite preform (10), and the secondary core (33?) a secondary inner preform (12); the gripper (4) is then driven (?3) in motion between the standby position (A) and a take-over position (B), wherein the injected preforms (10, 12) are cooled and taken over from the core side (31) by the gripper (4) by means of suction means (6); wherein the gripper (4) is further moved (?4) into a further operating position (C), in which it places the received secondary inner preforms (12) onto the respective primary cores (33) and continues to hold sai
