摘要：
An anvil (400, 500) for forming a transversal sealing (700) of a sleeve-shaped portion (104) of packaging material (102) holding a liquid product, said anvil (400, 500) comprising a main surface (402, 502), in operation, facing the tube (104), and a ridge (404, 504) provided on the main surface (402, 502), the ridge (404, 504) comprising a first section (406, 506) and a second section (208a, 208b, 508), wherein the first section (406, 506) of the ridge (404, 504) is placed below the second section (408a, 408b, 508) such that, in operation, a stress in the packaging material (102) formed by a hydrostatic pressure formed by the liquid product is shifted from a first part (702) of the sleeve-shaped portion (104) placed above the first section (406, 506) of the ridge to a second part (704a, 704b) placed above the second section (408a, 408b, 508).
