Abstract
An apparatus for applying an elastic tubular sleeve onto a splicing region between at least one pair of cables, wherein the tubular sleeve is supported in a radially expanded condition on at least one supporting element, may include axial-movement devices configured to axially move the at least one supporting element relative to the tubular sleeve at an adjustable speed, so as to cause a radial elastic shrinkage of the tubular sleeve capable of inducing an axial ejection thrust on the at least one supporting element, and counter devices configured to counteract the axial ejection thrust induced by the elastic shrinkage of the tubular sleeve.
Claims30
An apparatus for applying an elastic tubular sleeve onto a splicing region between at least one pair of cables, wherein the tubular sleeve is supported in a radially expanded condition on at least one supporting element, the apparatus comprising:
- axial-movement devices comprising at least one first abutment configured to operatively engage the tubular sleeve and at least one second abutment configured to operatively engage the at least one supporting element, the axial-movement devices being configured to axially move the at least one supporting element relative to the tubular sleeve at an adjustable speed, so as to cause a radial elastic shrinkage of the tubular sleeve capable of inducing an axial ejection thrust on the at least one supporting element;
- and
- counter devices configured to counteract the axial ejection thrust induced by the elastic shrinkage of the tubular sleeve.
An apparatus for splicing at least one pair of cables, each cable including at least one conductor, the apparatus comprising:
- at least one removable supporting element;
- an elastic tubular sleeve supported in a radially expanded condition on the at least one removable supporting element;
- axial-movement devices comprising at least one first abutment configured to operatively engage the tubular sleeve and at least one second abutment configured to operatively en age the at least one removable supporting element in order to axially move at least one portion of the at least one removable supporting element relative to the tubular sleeve at an adjustable speed, so as to give rise to a radial elastic shrinkage of the tubular sleeve capable of inducing an axial ejection thrust on the at least one removable supporting element;
- and
- counter devices configured to counteract the axial ejection thrust induced by the elastic shrinkage of the tubular sleeve.
