Abstract:
The invention relates to a method of conveying plastics material pre-forms, wherein the plastics material pre-forms are supplied to a conveying device by means of a supply device and the conveying device has a first roller body and a second roller body which extend substantially parallel to each other, and the plastics material pre-form is conveyed between these roller bodies, wherein a portion of the plastics material pre-forms is supported by the two roller bodies and wherein a further portion of the plastics material pre-forms passes through between the roller bodies. According to the invention at least one first value characteristic of a state of occupation of the plastics material pre-forms is detected by means of a first measuring instrument and a second value characteristic of the state of occupation of the plastics material pre-forms is detected by means of a second measuring instrument which is situated downstream of the first measuring instrument in the conveying direction of the plastics material pre-forms, and at least one setting variable of the supply device or the conveying device is controlled on the basis of the two values.
Abstract:
An apparatus for the conveying of plastics material containers and, in particular, plastics material pre-forms with a first roller arranged so as to be rotatable about its longitudinal axis, with a second roller arranged so as to be rotatable about its longitudinal axis, wherein the first roller and the second roller are arranged with respect to each other such that the plastics material containers can be conveyed between these rollers, wherein the plastics material container is supported by the two rollers during conveying. At least one roller has a main body produced from a first material and a layer which surrounds this main body in its peripheral direction and which is produced from a plastics material differing from the first material, wherein this layer acts as a contact layer for contacting the plastics material containers.
Abstract:
An apparatus (1) for the conveying of plastics material pre-forms (10) along a pre-set conveying path (P) with a first guide rail (2) and a second guide rail (4) for guiding the plastics material pre-forms (10), wherein the plastics material pre-forms (10) are guided between the guide rails (2, 4) and the guide rails (2, 4) have in each case first support faces (12, 14) which extend along the conveying path (P) and which support the plastics material pre-forms (10) during the conveying thereof. The apparatus (1) has a stressing device (42, 44) for acting upon the plastics material pre-forms (10) with a gaseous medium. The plastics material pre-forms are conveyed along their conveying path by being acted upon with the gaseous medium, and a geometrical position of the guide rails is capable of being altered with respect to each other.
Abstract:
A method of conveying plastics material pre-forms includes the plastics material pre-forms supplied to a conveying device by a supply device. The conveying device has a first roller body and a second roller body. The plastics material pre-form is conveyed between these roller bodies. A portion of the plastics material pre-forms is supported by the two roller bodies. A further portion of the plastics material pre-forms passes through between the roller bodies. At least one first value characteristic of a state of occupation of the plastics material pre-forms is detected by a first measuring instrument. A second value characteristic is detected by a second measuring instrument downstream of the first measuring instrument in the conveying direction of the plastics material pre-forms. A setting variable of the supply device or the conveying device is controlled on the basis of the two values.

Abstract:
An apparatus for the conveying of plastics material pre-forms along a preset conveying path with a first guide rail for guiding the plastics material pre-forms, with a second guide rail for guiding the plastics material pre-forms, wherein the plastics material pre-forms are capable of being guided between the guide rails and the guide rails have in each case first support faces which extend along the conveying path and which support the plastics material pre-forms during the conveying thereof. According to the invention the apparatus has a stressing device for acting upon the plastics material pre-forms with a gaseous medium, which stressing device is designed in such a way that the plastics material pre-forms are conveyed along their conveying path by being acted upon with the gaseous medium, and wherein a geometrical position of the guide rails is capable of being altered with respect to each other.
