A covering device (10) is described for applying an elastic cover to an elongate object (1), comprising: a folded elastic sleeve (12) having an inner sleeve portion and at least one coaxially disposed outer sleeve portion (13,14) overlaying said inner sleeve portion, said inner and outer sleeve portions (13,14) being continuously joined at least at one circumferential edge; a support (16) for holding said folded elastic sleeve (12) in a radially stretched condition, said support (16) having a first end (18,19) arranged adjacent to the continuous join of said outer and inner sleeve portions (12; 13,14), relative movement between said outer sleeve portion (13,14) and said inner sleeve portion (12) resulting in said outer portion (13,14) moving and recovering onto the elongate object (1); and said support (16) further including stress relief means (20,22) associated with said first end (18,19) for reducing the stress in said outer sleeve portion (13,14) in the part thereof adjacent said first end (18,19) of said support (16) when said outer sleeve portion (13,14) has been moved onto the object to be covered (1). <IMAGE> |
