Abstract
A blow moulding machine for blow moulding a container having an integrally formed handle; said container blow moulded from a previously injection moulded preform; said preform comprising a body portion and said integrally formed handle; said machine including a preform loading station at which said preform is oriented by a preform orienting apparatus.
Claims5
A method for controlling a preform for stretch blow molding therefrom a container with an integrally formed handle, said preform comprising a body portion and said integrally formed handle;
- said integrally formed handle including a deflectable portion;
- said preform transferred from a preform supply source to a blow molding tool for blowing said container, said method including the steps of:
- a. passing said preform through a preform handle orienting apparatus;
- b. transferring said preform to a preform transportation system;
- c. setting heat outputs of individual preform heating elements to deliver a required distribution of heat density to said body portion of said preform whilst the preform is progressed by the transportation system towards the blow molding tool,
- d. transferring said preform from said transportation system to said blow molding tool;
- e. accommodating the body portion of the preform and the integrally formed handle in a cavity volume defined by a multi-part cavity of the blow molding tool;
- f. stretch blowing, the preform whilst the preform is within the cavity volume;
- g. the integrally formed handle including a deflectable portion which moves within the cavity volume during the step of stretch blowing the preform.
