A product conveying and accumulation system, comprising: (a) a first conveying means for the movement of products from an upstream station to a guide means; (b) a second conveying means arranged to receive products directly from the first conveying means, for accumulation and movement of products on and around the second conveying means and for delivery of products directly to the first conveying means or to an other conveying means for movement to a downstream destination, at least one section of the second conveying means being in substantially adjacent, side by side alignment with at least one section of the first conveying means, the adjacent alignment between both the conveying means extending from an upstream location of the first conveying means to at least the guide means, both conveying means moving in the same direction (9, 23) at all times when in adjacent alignment; and (c) said product conveying and accumulation system comprising said guide means, characterised in that said guide means comprises: (i) a first section having a first surface for directing products from the first conveying means onto the second conveying means; (ii) a second section having a second surface for directing products from the at least one adjacent section of the second conveying means onto an accumulator section of the second conveying means for accumulation on the second conveying means; and (iii) a guide channel defined between said first and second sections (42, 44) of said guide means, for directing products from the second conveying means to the first conveying means or to said other conveying means for movement to the downstream destination. (a) a first conveying means for the movement of products from an upstream station to a guide means; (b) a second conveying means arranged to receive products directly from the first conveying means, for accumulation and movement of products on and around the second conveying means and for delivery of products directly to the first conveying means or to an other conveying means for movement to a downstream destination, at least one section of the second conveying means being in substantially adjacent, side by side alignment with at least one section of the first conveying means, the adjacent alignment between both the conveying means extending from an upstream location of the first conveying means to at least the guide means, both conveying means moving in the same direction (9, 23) at all times when in adjacent alignment; and (c) said product conveying and accumulation system comprising said guide means, characterised in that said guide means comprises: (i) a first section having a first surface for directing products from the first conveying means onto the second conveying means; (ii) a second section having a second surface for directing products from the at least one adjacent section of the second conveying means onto an accumulator section of the second conveying means for accumulation on the second conveying means; and (iii) a guide channel defined between said first and second sections (42, 44) of said guide means, for directing products from the second conveying means to the first conveying means or to said other conveying means for movement to the downstream destination. (i) a first section having a first surface for directing products from the first conveying means onto the second conveying means; (ii) a second section having a second surface for directing products from the at least one adjacent section of the second conveying means onto an accumulator section of the second conveying means for accumulation on the second conveying means; and (iii) a guide channel defined between said first and second sections (42, 44) of said guide means, for directing products from the second conveying means to the first conveying means or to said other conveying means for movement to the downstream destination.
