Abstract

A machine for fitting a sleeve seal to a container or other object without twisting of the sleeve seal and tearing or crumpling of a label on the container by the sleeve seal, which is attained by providing flexible guide members arranged on a streamline-form mandrel, a recess on the bottom of the mandrel, into which the container over which the sleeve seal is to be fitted can be received, and a feed member which is pivoted away from at operating position to disengage position.

Claims

1. A sleeve seal fitting machine, for fitting a sleeve seal over an object, comprising:

a streamline-form mandrel adapted to be positioned with its lower end over the object, the size of the lower end being greater than that of the object;

a means for supplying the sleeve seal to the upper end of the mandrel;

a feed member for pushing the sleeve seal along the mandrel toward the object;

an upper and a lower means for clamping the mandrel, which are adapted both to hold the mandrel and to move it axially towards and away from the object, and which bear on axially different parts of the mandrel;

and flexible guide members mounted on the mandrel which resiliently stand proud of its surface, so that as the sleeve seal is pushed along the mandrel said guide members tend to prevent it twisting.

2. The machine of claim 1, wherein each of the flexible guide members is formed in two parts which are axially spaced from one another along the axis of the mandrel and separated from one another by a portion of the mandrel on which the upper clamping means bears.

3. The machine of claim 1 or 2, wherein the lower end of the mandrel is formed with a recess for receiving the upper end of the object, and wherein the mandrel is tapered.

4. The machine as set forth in claim 2 wherein means are provided to pivotally move the feed member away from an operating position as soon as it has finished pushing the sleeve seal from the mandrel.
