Abstract
The application relates to a connecting device for connecting a tubular film to a device to transfer a product, in particular in powder/granular form, through the tubular film into and/or out of the device, the connecting device including: a base body forming a channel through which the product flows during transfer, wherein the channel extends along a channel axis and ends at an opening of the base body and opens to the outside; an adjustable sealing device being adjustable between (i) a connecting position in which it is spaced from the base body and allows the tubular film to be drawn over the base body, and (ii) a sealing position in which it seals the tubular film drawn over the base body with respect to the base body for transferring the product; and a clamping device which runs around the base body and is configured to clamp the tubular film drawn over the base body in a sealed manner in a clamping region by pressing the tubular film flat against the base body in the clamping region without changing its course; wherein the adjustable sealing device can be moved into an intermediate position located between the connecting position and the sealing position, in which it presses the tubular film drawn over the base body without changing its course onto a film remnant clamped in the clamping device, which originates from a previous transfer, in such a way that the film remnant rests against the base body and can preferably be pulled manually into the channel after the clamping device has been released.
